Can Wi-Fi Extenders Just Stop Working?

They can indeed. And it can be handy to know the signs if an extender is about to fail.

Disclaimer: Here at Geekabit, we don’t actually recommend Wi-Fi extenders as a solution to Wi-Fi problems. There are usually other more effective solutions that can be put into place with a little help from Wi-Fi experts like ourselves. However, we also know that people don’t always heed expert advice… So, here are some useful tips to keep in mind if you do go down the Wi-Fi extender route. And if that doesn’t work, you’ll know who to call. 

Just like other electronic devices, Wi-Fi extenders can fail. Whilst they do tend to last a decent amount of time and generally don’t need too much maintenance or repairing, they still won’t last forever. As with anything in the tech world, components will start to wear out and older extender models will become obsolete with the emergence of new technologies. Let’s take a look at some of the main issues that could stop a Wi-Fi extender from working.

Why has my Wi-Fi Extender stopped working? 

There could be a number of reasons why Wi-Fi extenders might stop working earlier than you would expect. The number one reason for a Wi-Fi extender to break down is heat. 

Overheating

Like other electronic devices, Wi-Fi extenders generate heat. However, they don’t have fans or anything else to keep the heta from building up, so rely on passive cooling. This can be a big problem when they are switched on all the time, never getting the chance to cool down. 

To prevent a Wi-Fi extender from failing too soon due to overheating, there are a couple of things you can keep in mind. 

  • Place the Wi-Fi extender in a place where there is plenty of air flow around it e.g. an open book shelf
  • Avoid places where there is less air flow like shelving units, cupboards, cabinets or enclosed spaces

Dust

How often do you clean your Wi-Fi devices and hardware? A simple, regular clean of your Wi-Fi extender can help extend its life. Whilst we wouldn’t recommend taking a Wi-Fi extender apart to clean inside it, it’s definitely worth the effort to check the vents on it and blow away any dust.

New Technologies

As with any kind of Wi-Fi hardware, things do become obsolete over time as new technologies are developed and introduced to the market. 

A popular reason for people to replace their Wi-Fi extenders is to make sure that their extended network is as fast and can handle as many devices as their primary network. 

When should I replace my Wi-Fi extender?

If everything is working to your satisfaction, then there’s no need to replace anything. However, if you’ve been googling ‘do I need to replace my Wi-Fi extender?’ then you’re probably already experiencing problems and looking for the solution! 

Preemptive replacement of Wi-Fi hardware would usually be for crucial network components, for example, your router. Wi-Fi extenders aren’t usually as important, so there’s usually no need to replace them until they break. 

However, if you are relying on your Wi-Fi extender to provide internet access to parts of your home or to devices that must be connected (for example, perhaps a garden office or CCTV cameras) then you may feel it’s more important to stay ahead of problems and replace them before issues arise. 

There isn’t really a set time frame for replacing a Wi-Fi extender – They can last for as long as ten years, maybe more. But there will come a time when internal components will start to fail as they naturally start to degrade. In scenarios like the above where your Wi-Fi extender is fulfilling a vital function, you might want to consider replacing it on a shorter timeframe e.g. every 5 years perhaps or when you notice any reduction in performance.  

Can I tell if my Wi-Fi extender is starting to fail? 

Unfortunately, there’s rarely obvious signs that a Wi-Fi extender is beginning to fail. They tend to work one day, and not work the next. There may be some clues that it’s starting to degrade, which we’ll outline below, but this may not always be the case. 

Possible signs that your Wi-Fi extender is starting to fail:

  • Having to regularly reset the Wi-Fi extender. Whilst doing a factory reset may fix the issue, if you’re having to do this a lot then it’s probably time to consider replacing it. 
  • Difficulty connecting to the Wi-Fi extender. If interference isn’t an issue, but your devices are having trouble connecting or staying connected then it might be time to replace the extender. 
  • Slow internet speeds. If your connection is suddenly slower one day, then there is likely a problem with the extender. Also bear in mind that if your extender is older than your router, then it likely won’t support the latest Wi-Fi technology available to your router, hence causing a slower connection in the extended area. 
  • Dropped connection. If you can connect a device to your primary network, but it drops out when connecting to the extender then there is likely a problem with the Wi-Fi extender. 
  • Error lights. If lights on the extender are the wrong colour, flashing or not on at all then there is likely an issue. Check the manufacturer’s instructions to find out what the lights mean and how to resolve the problem. 
  • Unable to turn the Wi-Fi extender on. It may have overheated, so let it cool down and then try again to turn it on. You could also try plugging it into an alternative outlet. Pressing the rest button may also help with this issue. If after trying these things it still won’t turn on then it’s probably time to replace it. 

How can I help my Wi-Fi extender last longer?

No hardware can last for ever, so eventually all Wi-Fi extenders are going to fill and need replacing. That being said, there are some things you can do to take good care of it and help it to last as long as possible. As we noted above, the most common problems are caused by heat, so the main solutions lie in keeping the gear cool. 

Help your Wi-Fi extender have a long life using these tips:

  • When you’re setting up, always place your Wi-Fi extender in a well-ventilated area. Never place it in an enclosed space like a closed shelf or cabinet. Not only will an enclosed space block the Wi-Fi signal, but it will also cause the extender to get hotter than necessary, which will shorten its life. 
  • Use a surge protector in the same location as the Wi-Fi extender if possible. This can help stop voltage spikes which can cause severe damage to a Wi-Fi extender. 
  • Regularly give the extender a clean and remove dust by dusting the outside of it and blow dust from the vents. Dust build-up can also contribute to overheating.
  • Sometimes firmware updates from manufacturers can help keep performance at its best. If you notice worsening performance then it’s worth trying to install a firmware update (if there is one) to help speed up an older Wi-Fi extender model. 

Is my Wi-Fi extender causing network issues?

Problems with Wi-Fi connectivity and speed are the first clues when it comes to identifying if a Wi-Fi extender is failing or starting to fail. 

Got a unique SSID for your extender? Then you’ll notice right away that you’re having problems connecting to it compared with your primary network. 

Using a mesh network? If you’re using the same SSID and password for your extended network as your primary network or using a mesh network then you might notice you have connection trouble or slow internet speeds when you’re in the extended network area. 

As you’ll remember from our disclaimer at the start of this article, here at Geekabit we don’t recommend Wi-Fi extenders. One of the reasons why we don’t is that they can cause problems for your network even when they’re working. 

One of the biggest problems with Wi-Fi extenders is that they can actually cause interference on your primary network if they’re running on the same channel. So by trying to extend your network to a further area of your house and garden, you could be jeopardising your main network connection. 

This issue is reduced when using a mesh network as they create one big network where devices are seamlessly passed from one extender to the next. However, your bog-standard Wi-Fi extenders can cause real issues with your main Wi-Fi router if they’re operating on the same or overlapping channels. 

If you’re trying to create a reliable network across a large space and finding a regular router isn’t quite cutting it, then it might be time to call in the experts rather than reaching for the extenders. Give our friendly Wi-Fi engineers a call and we can identify the best Wi-Fi solution for your premises.

Is Your Broadband Router Open to Hackers? Survey Says Yes 

Broadband Genie, the independent UK comparison service for telecoms and broadband, have published a new survey revealing some pretty shocking statistics when it comes to internet safety. 

3,045 internet users were surveyed between the 1st January and 26th April this year, revealing that:

  • 89% of respondents have never updated the firmware of their home router 
  • 86% have never changed the device’s administrator password 
  • 72% have never changed their Wi-Fi password
  • 75% have never checked to see what or who is linked to their router
  • 52% have never changed or updated their routers settings

Are you guilty of any of these? No shaming from us, but let’s take a little look at why ignoring these things when it comes to your router and security isn’t a great idea. 

Why should I change my router from the default password? 

If you leave your router set to the default password, it could allow hackers to identify which make and model of router you are using and work out the password.

Thankfully, many ISP’s supply long, randomised passwords with no real structure, making it harder to identify.  

Do I need to update firmware on my router? 

Many routers that come as part of a bundle directly from your ISP are thankfully set up to auto-update their firmware – Meaning you, the customer, don’t have to actually do any specific actions in order to keep your device up-to-date. 

However, it’s probably a good idea to check with your broadband provider to confirm this is the case.

And don’t forget, many security and firmware updates are done at night – So don’t switch your router off overnight. 

If you have purchased your router separately from an ISP bundle, then you may be required to carry out this action yourself to check for recent firmware updates. Remember that not all firmware updates are particularly accessible or easy to find, so you may need to seek support from the manufacturer. 

It’s vital not to leave security vulnerabilities unpatched – And even some relatively modern pieces of kit could be susceptible to security risks. 

What’s the reason behind people not changing their router password?

The survey respondents who had answered that they had never changed their router’s factory settings were then asked why they had not. The answer that 75% of those surveyed gave was that they didn’t know they needed to change it. 

Your router is the single most important security device in your home network

It’s often the case that the router is the most important device in your home network when it comes to internet security. 

Changing your router’s password from the default to a strong alternative protects your network, particularly if the password from your ISP is not properly randomised or ineffective. 

It’s a good rule of thumb to assume that your router does not come secure out of the box. And if consumers are unaware of the risks, then clearly more awareness needs to be raised surrounding these security risks. 

That’s where the Product Security and Telecommunications Infrastructure Act comes in. 

The Product Security and Telecommunications Infrastructure Act

On the 29th April 2024, the Government brought in the Product Security and Telecommunications Infrastructure Act. This includes their new Secure by Design policy, which means that device makers (retailers and manufacturers) that fail to comply can be hit with financial penalties. 

Changes include:

  • The banning of easily guessable default passwords (like ‘admin’ or ‘12345’) so that vulnerabilities and hacking are prevented
  • The prompting of users to change the default password
  • Improved support for security issues by supplying contact details of manufacturers so that bugs and issues can be dealt with 
  • The requirement to state how long related network products will be supported by security patches (firmware updates)

These changes don’t just apply to routers – They also cover smartphones, televisions, games consoles, internet-connected fridges and other smart home devices such as doorbells etc. 

Are you confident that your router is secure?

IoT Devices Mobile Broadband Mobile COnnectivity Mobile Network Network RSRP RSSI Teltonika Wi-Fi Wireless Network
Teltonika Network Setup – What is RSSI and RSRP? 

Enable yourself to get better understanding and control of your Teltonika networking solution’s performance with wireless connection support display RSSI and RSRP signal strength. 

Familiarising yourself with RSSI and RSRP metrics wireless network support will help to enhance your Teltonika Networks next steps. 

Wireless Networks are the preferred choice for IoT connectivity

When it comes to IoT (internet of things) applications, wired connections once held dominance. But it is becoming increasingly evident that the preferred choice for IoT connectivity is wireless networking. 

The wireless connectivity market is expected to continue to grow at a compound annual growth rate of 12.8% in the next 3 years, solidifying the trend of networking solutions becoming increasingly dependent on Wi-Fi or mobile networks. 

Due to the versatility and convenience offered by wireless connectivity, this doesn’t come as much of a surprise. 

Without the limitations of wiring, network devices can be configured, monitored and managed remotely – Even if they’re in a different city, country or continent. 

The benefits of using a wireless connection are indisputable.

What are the primary connectivity options? 

There are 2 primary choices when it comes to wireless connectivity: Wi-Fi and mobile technology. 

Wi-Fi 

  • Operates on the IEEE 802.11 standard
  • Supports multiple protocols including 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac (determining the connection’s speed and range)

Mobile Technologies

  • Have evolved from 3G to 4G to 5G
  • Each defines the connection’s speed and capacity available to users and end devices

RSSI and RSRP

Whether your network device operates on Wi-Fi or mobile technologies, if you’re checking out your network then you’ll likely come across RSSI and RSRP metrics. These metrics are vital for displaying the strength and power of your connection. 

What is RSSI, what does it do and how is it measured? 

  • RSSI stands for Received Signal Strength Indicator. 
  • At the moment radio frequency power and quality reaches the receiver, it’s measured by RSSI. For example, a network device or antenna. 
  • RSSI can be used to gauge the strength of the signal in any wireless system, it’s not exclusive to any one type of wireless technology. 
  • Whether you’re using Wi-Fi or mobile technologies, RSSI can provide signal strength data across different types of radio frequency communications. 
  • This means that RSSI can be a good indicator of whether your network devices have robust connectivity.
  • RSSI signal strength is measured in negative values, with stronger, higher quality signal values being closest to zero.
  • NOTE: RSSI values are not standardised across industries, so bear this in mind when interpreting network data for devices manufactured by different companies. 

What is RSRP? 

  • RSRP stands for Reference Signal Received Power and is measured in negative values.
  • RSRP is particularly relevant for mobile technology network solutions like 4G and 5G.
  • It is a type of RSSI measurement, but used to measure the power of mobile signals spread over full bandwidth and narrowband.
  • RSRP measurements can help you to see your network’s overall signal coverage and capacity across all frequencies used for your networking solutions by measuring across the full bandwidth.
  • The quality of your connection in specific frequency ranges can be assessed by measuring RSRP over a narrowband. This can be used to troubleshoot specific issues that could affect signal quality as well as optimising network performance.
  • By using the RSRP signal strength, you can determine a more precise measurement of the cellular connectivity that your network receiver obtains. Having this information can enable you to make informed decision about your network infrastructure as well as Quality of Service Assessments and further improvements.
  • NOTE: Just as with RSSI, the RSRP signal strength can differ by manufacturer.

Your Teltonika Network

Both RSSI and RSRP signal strength indicators are displayed for Teltonika Network devices enabled with Wi-Fi or mobile connectivity devices.

The display of these metrics can be accessed via RutOS. The latest 7.06 version of RutOS has enhanced data visualisation capabilities for mobile connections.

5G 5G Mobile Broadband Broadband Drones Mobile Broadband Mobile COnnectivity Mobile Network Network Rural Broadband Satellite Broadband Search and Rescue Communication Wi-Fi
Connections Boosted by VMO2 5G Drones for Search and Rescue Missions

Here at Geekabit we talk a lot about the problems that rural areas face when it comes to connectivity – Whether it’s mobile or broadband. 

Mostly we’re talking about businesses and homes that struggle with more traditional forms of broadband internet connectivity as well as mobile broadband options. 

But what about organisations that rely on connectivity outside the normal 4 walls of business premises?

For Search and Rescue teams, staying connected couldn’t be more vital. Yet, they’re often plunged into rural and remote locations trying to find someone missing and potentially hurt. 

So how can we make sure that these Search and Rescue teams stay connected with their base and are able to utilise location data? 

Virgin Media O2 (VMO2) has come up with just the solution. They’ve recently developed a 5G-connected drone that is specifically designed to bolster the communication that is so vital to Search and Rescue teams. 

Who is trialling this 5G drone for Search and Rescue teams? 

The first Search and Rescue team to trial VMO2’s 5G drone is Warwickshire Search and Rescue team.

As we said above, communication in remote and vast terrains is absolutely vital but can be a challenge for Search and Rescue teams. As the work of these teams is so time critical, it’s essential that their effectiveness is unhindered by communication and connectivity problems. 

As a Lowland Rescue Unit, the Warwickshire Search and Rescue team play a vital role in locating vulnerable missing persons alongside the police. 

With a 45% increase in callouts between 2020 and 2022, the demand for their services continues to surge with 65 callouts in 2023 – That’s more than 1 per week. 

How does VMO2’s 5G drone work?

The 5G Technical Trials Team over at VMO2 saw this need for critical connectivity and devised a portable solution that uses a network of low earth orbit (LEO) satellites. The portability and compactness of the tech means that it’s small enough to be integrated into a drone. Ideal for vast, remote spaces. 

This easy-to-deploy drone acts like a flying mobile phone mast, enabling Search and Rescue teams to stay connected via seamless 5G connectivity regardless of their location.

What do VMO2 have to say?

Here at Geekabit we love to see how innovative thinking and technological advancements combine to create fresh ideas and impactful solutions to a whole range of problems. 

Head of Technical Trials for Virgin Media O2, David Owens, says:

“This project is a further example of how fresh-thinking and 5G technologies can be combined to provide real societal benefits.

“The solution has the potential to transform how search and rescue teams operate and respond to life-threatening situations, enabling them to make faster and more decisive decisions. We’re enormously proud that our connectivity will be able to help these teams to save lives.”

What do Warwickshire Search and Rescue make of the 5G drone?

Trustee and Search Technician at Warwickshire Search and Rescue, Steve Brown says: 

“With more and more callouts each year, this drone with mobile connectivity is a powerful tool for our team to understand and assess a situation immediately, saving crucial time in life-threatening situations.

“It means we will always be connected, ensuring seamless communication and efficient coordination throughout our missions. As a result of this, we will connect the unreachable, save lives, and inspire a new era of technological possibilities.”

There’s no doubt that this innovative use of 5G mobile connectivity is a fantastic example of how technology can be used in even the most hard-to-reach places. 

In the UK, someone is reported missing every 90 seconds. The more swiftly that person can be located, the better the outcome. For those that have gone missing in a remote area, a Search and Rescue team that can stay reliably connected will be a huge advantage. 

As Portfolio Holder for Fire & Rescue and Community Safety at Warwickshire County Council, Councillor Andy Crump said: 

“The Warwickshire Search and Rescue team do such vital work for our local community by assisting the police in searching for missing people. 

“This new solution from Virgin Media O2 will help the team on these missions and ultimately save many lives. It is further evidence of the positive impact improved connectivity can have upon our society.”

We’re looking forward to seeing how 5G drones and satellite broadband technology can be accessed in more remote areas and rural locations.

Ethernet Ethernet Cables Fibre Broadband Media Converter Network WLAN
Do You Need a Media Converter for Your Network?

 Networking and Media Converters have gone hand in hand right from the start. They play a vital role when it comes to solving interconnection problems in networks. 

If you oversee a business network (or one in a large home) then you probably already use this handy device. But are you using the media converter correctly? 

What is a media converter?

A media converter is a networking device that allows you to connect one type of communication protocol cable to another different type of cable. For example, connecting a twisted pair to fibre optic cable. 

By connecting two different media, like Ethernet copper and Ethernet fibre, they can typically connect devices that are beyond 100 metres from the nearest available switch. 

The reach of the copper port can be extended with a copper to fibre converter by connecting a copper port on an Ethernet switch to the fibre that connects the device in the remote location.

The ability to do this provides great flexibility when building and connecting networks, easily connecting fibre and copper cables.

A media converter is usually a two-port device equipped with a copper interface on one side and a fibre interface on the other side.

Another key building block within a network are Switches. They enable you to connect multiple devices, such as computers, wireless access points, printers, and servers;  All on the same network within a building or campus. A switch enables connected devices to share information and talk to each other.

Switches are mostly made up of LAN ports which are usually copper Ethernet with a few fibre-based uplink ports. They are also often SFP-based (small form-factor pluggable used for data communication). The copper ports are used to connect devices within a short-range (up to 100 metres) while the SFP uplinks can connect devices that are further away (which would be useful for other switches and/or servers).

The goal for any well-designed network is to use all the available uplinks. This maximises throughput. Oftentimes, spare LAN ports are kept in order to be able to easily connect new devices in the future. However this only works well if the device is within 100 metres from the switch. It can also cause problems if it is in a ‘noisy’ environment – A copper cable can be susceptible to electromagnetic interference. 

In what sort of situation could we see these issues arise?

  • A computer placed in a remote location
  • An access point in an outdoor area
  • A video surveillance camera
  • An access control system far from the last switch, 

For instances where the LAN must be extended over 100 metres, you will require a network extender, and a media converter would be the ideal solution. 

To extend a network to a distant location, you would use a fibre connection from the switch and a media converter to connect to the device.

The remote device problem is solved with the Ethernet link providing a very long reach thus extending the connection. It also saves you from having to add other switches to the network. 

How Does a Media Converter Work?

Media converters can be split into two main groups. 

The first type of media converter can only convert physical media. For example,copper to fibre, or fibre to copper, without adjusting the speed of the link. This type of device is most commonly used when latency is a critical factor, in other words, when a time delay when transmitting the traffic is unacceptable during conversion. 

The second type of media converters are often called switch converters or rate converters. These are a standard Ethernet switch equipped with two ports. These devices can adjust both the media and the link speed so that it is possible to connect a 10/100/1000T port to a 100FX port. For time-sensitive applications, this type is unsuitable as the switch adds a small amount of latency to the connection.

Do media converters work in both directions?

Yes, they can work in both directions. Media converters work with bidirectional links, so the same model can be used to convert copper to fibre but also fibre to copper. 

If you use these devices in pairs, you can use the same model for both ends since they work both ways.

What Are the Different Types of Media Converters?

There are different types of media converter, including:

  • One that connects fibre and copper cables (the most common)
  • One that can convert Ethernet to VDSL 
  • One that can inject Power over Ethernet (PoE)

Typically, media converters are small standalone unmanaged devices. However, they can also form managed and unmanaged chassis solutions to integrate multiple devices within your network in a 19″ standard rack. For deployments in harsher environments, industrial media converters can be mounted in DIN cabinets to protect the electrical components.  

What is the most common model of media converter? 

As we mentioned above, the most common model of media converter is one which connects copper to fibre with one RJ45 port and one fibre port or SFP bay. To allow another converter or a switch equipped with the appropriate interface to be connected easily, the transport protocol is always Ethernet. 

What about legacy infrastructure?

It’s not always possible to use a fibre link due to legacy infrastructure, for example twisted-pair phone cables or co-ax cables. If these are already in use, replacing with new fibre is not practical. Media converters that convert Ethernet to co-ax or Ethernet to twisted-pair allow the use of legacy infrastructure. 

These devices can reach long distances over legacy cables due to using VDSL (Very high Data rate Subscription Line) technology.

As mentioned above, another type of converter can provide Power over Ethernet (PoE) on the copper Ethernet port to power remote devices. This is particularly useful for things like CCTV cameras or access control gates, and helps to simplify deployment of physical security solutions.

Covering the most commonly used interfaces today, media converter port speeds include Fast Ethernet, Gigabit and 10 Gigabit. Transceivers through an SFP port are able to operate on fibres from just a few metres in length up to 120km, satisfying a wide range of distances and speeds.

Media converters are useful for desktops too

Did you know that media converters can be used on the desktop too? 

The USB to fibre Ethernet media converter acts as a Network Interface Card for your desktop or laptop – Quickly deploying a Fibre To The Desk (FTTD) solution for security-sensitive applications, or those more than 100 metres from the switch.

What Are the Features of a Media Converter?

The majority of media converters are not smart devices, however there are some media converters that have smart features that can help to simplify the management of large networks. 

‘Have you turned it off and then on again?’

We’ve all heard that old IT joke. But actually there’s a reason why IT guru’s and network engineers say those notorious words. One of the most common ways to solve computer-related issues is to ‘power-cycle’ the device – Often, simply turning it off and then on again makes the problem disappear. 

For PoE (Power over Ethernet) powered devices, disconnecting the power on the switch port connected to the device having issues will automatically reset it. 

However, most media converters are not managed remotely and thus any that are on a remote site cannot simply turn the power off. In this case, a network engineer (or other person) would have to physically go to the remote site and disconnect and then reconnect the PoE cable. 

Some configurable PoE Media converters enable PoE power to be reset whenever the fibre connection is turned off and on. This ‘smart’ feature would prevent the need for a physical remote site visit by enabling you to control the PoE power via the fibre connection on the switch, resetting the remote device.
