Are My Wi-Fi Issues Caused by Wi-Fi Interference?

Since 1997, when Wi-Fi emerged into the consumer world, it’s become integral to everyday life. For many it’s a vital way of staying connected with friends, family and colleagues – At home, at work and even out and about.

We tend to take it a bit for granted, when in actual fact we probably feel like we couldn’t live without it – Especially during 2020! And like so many things – We really only notice how much we depend on it when it’s not there. Much like when there is a power cut and all the lights go out – When Wi-Fi isn’t working properly, we really feel it’s absence.

Is there anything quite as frustrating as dodgy Wi-Fi?

Technology wouldn’t be technology without its issues, and Wi-Fi is no exception. So what can cause Wi-Fi problems? One of the biggest issues to affect how successful and reliable a Wi-Fi connection is, is Wi-Fi interference. In this blog we’re going to be looking at how you might go about detecting whether your Wi-Fi woe is an interference issue

How do I know if my Wi-Fi issue is due to Wi-Fi interference?

Here are a couple of problems you may experience if you are having trouble with Wi-Fi interference.


  • Trouble with signal strength, and having low signal despite being in close proximity to a Wi-Fi broadcast device like a router
  • You have no connectivity issues when using a wired connection, but have a considerably slower connection when connecting using Wi-Fi
  • Trying to transfer files between computers using Wi-Fi, and finding it very slow
  • Being unable to pair devices using Wi-Fi or Bluetooth despite being in close proximity to the receiver
  • Your Wi-Fi connection Intermittently dropping out


If you are experiencing one or more of these annoying Wi-Fi issues, then it’s quite possible that something is causing interference with your Wi-Fi.

There are two main types of Wi-Fi Interference – Physical and Frequency. We’ll be covering some examples of each of these in next weeks blog. Check back then to see how you can identify what may be causing your Wi-Fi interference issue, and how you can go about fixing it.

If you require any Wi-Fi help in the meantime, then please don’t hesitate to give our Wi-Fi experts a call. We’re still working under the current government guidelines, and mainly operating out of Hampshire and London. Don’t let dodgy Wi-Fi be the reason you can’t find a connection.

It’s Business As Usual for Geekabit

We’re still here, and we’re not going anywhere.

We are lucky that much of our work is done remotely. And for situations where this isn’t possible, we are fortunately able to continue working within the government guidelines.

As the nation once again faces a period of lockdown, we thought we would link some previous blogs that might prove useful in the coming weeks.

Whether you’re in work or find yourself working from home again, you might well encounter some Wi-Fi problems. Thankfully, many of them are pretty common and are relatively easy to fix. The below blog will give you some top tips to keep you connected.

Common Wi-Fi Problems and How to Fix Them

Got yourself such good Wi-Fi that your neighbour’s sneaking on? You need to make your connection more secure. Here’s how.

Who is Stealing my Wi-Fi and How Can I Block Them?

Desperate for a bit of time out of the house? Bet you never thought you’d be longing for the office! The weather might be turning a bit too chilly to be enjoying the sunshine mentioned in this next blog, but it could help get your Wi-Fi set up in the garden shed. Don’t forget your hot water bottle and flask of coffee!

How do I get Wi-Fi in my garden?

A reliable, fast connection is once again going to be the thing to keep us connected – To colleagues, friends and family. Don’t let rubbish Wi-Fi be the thing that isolates you.

As we said, we’re still here for all your Wi-Fi needs. Perhaps you’re thinking that a business empty of employees and customers is the best time to finally get your patchy Wi-Fi sorted. In which case, do give our Wi-Fi experts a call. Operating out of London, Cardiff and Hampshire, our engineers can provide a Wi-Fi site survey, plan and design your new Wi-Fi network and then install it for you.

Maybe your home Wi-Fi network isn’t cutting it for all your zoom calls? Over the past couple of months we’ve installed a number of 4G broadband kits in place of intermittent Wi-Fi, especially in more rural areas.

To discuss any of the above, please get in touch with us today.

How to Measure RF Attenuation Through a Wall
Are you having problems with your Wi-Fi? Perhaps you didn’t carry out a Wi-Fi survey prior to designing and installing your network – Or maybe you skipped the design bit altogether!


Dodgy Wi-Fi can sometimes be put down to attenuation, or loss of signal. The main causes of this are the distance the signal is travelling from the transmitter, and objects in the way like walls.

It’s paramount that when you are designing a Wi-Fi network in a walled environment like an office, that you take into account things like walls and their attenuation values. These values can then be used in the design process, indicating where best to place devices and simulate any potential problems that may arise.

Not all walls are the same. Different materials will have a different attenuation value – Basically, some walls will block Wi-Fi signal more than others. Some may be plasterboard, or using plasterboard as a disguise over another material such as brick, concrete, or other materials.

Whatever the material, it’s important to identify what it is and how successfully a signal can get through. Here’s how you can go about measuring the attenuation of  a wall.


What you will need:
  • Something to generate Wi-Fi. This could be the hotspot function on your smartphone, a WLAN Pi in hotspot mode powered by a USB, or a battery pack powered Enterprise grade AP. You need to be able to control the transmitting power and the channel so that your measurements will be consistent.
  • A device with which you can measure Wi-Fi. This can also be done with a smartphone through AirPort Utility on iPhone or Aruba Utilities on Android. You could also use an AirCheck G2 or an Ekahau Sidekick. The device you choose will need to enable you to scan only the channel your Wi-Fi generating device is on.


What to do:
  1. Identify the wall you are wishing to test.
  2. Place the Wi-Fi generating device at least 4m from the wall, with nothing in-between the device and the wall.
  3. On the measuring device, set the channel to only the scan the channel that your generating device is using.
  4. Point the measuring device towards the generating device on the near side of the wall, making sure that there is a direct line of sight between the devices. Make sure you do not sit or stand between them.
  5. Take a few sets of measurements and make a note of the values. Identify the average for the near side of the wall. You could call this A.
  6. Next, move the measuring device to the other side of the wall, directly in line with where it was before. Again, point the measuring device towards the generating device.
  7. Just like before, take a few sets of measurements and make a note of the values. Identify the average measurement for the far side of the wall. You could call this B.
  8. Work out the wall attenuation: A – B. Make a note of this and document it.


Now you know how much the wall is (or isn’t) blocking the Wi-Fi signal. This can help you identify the best positions for devices like routers and access points when designing and installing your Wi-Fi network.

Thinking this all sounds a bit complicated? Luckily for you, our expert Wi-Fi engineers here at Geekabit are pros at carrying out this sort of investigation. We offer site surveys, Wi-Fi design & planning and Wi-Fi installation.

If you already have a Wi-Fi network set up, but have a sneaking suspicion that a particular wall might be causing you problems then we can also help diagnose any Wi-Fi issues in an already established network.

Three types of Wi-Fi wireless network
There are three main types of wireless network – How do you know which wireless network is right for you?

Here we’re going to talk about three wireless networks to help you identify which would work best for your business.

We’ll be looking at centralised deployment, converged deployment and cloud-based deployment to see which one suits different types of applications.

Centralised Deployment

The most common wireless network system is centralised deployment. These lend themselves well to environments where buildings and networks are all in close proximity. This type of deployment brings the wireless network together which helps to facilitate advanced wireless functionality. It also enables easier upgrades. Wi-Fi controllers in these networks are based on-site, installed in a location at the centre of the network.

Converged Deployment

This type of wireless network works well for smaller environments such as an office building. They offer a consistency for both wireless and wired connections due to combining them both onto one network device. This device is an access switch which acts as both a switch as well as a wireless controller.

Cloud-Based Deployment

This deployment is ideal for networks that cover multiple locations. Devices connected on the premises of these different locations are managed by cloud software which via a dashboard, enables full visibility and management of said devices.

Once you’ve identified which network your business needs, you can then go about designing it. A site survey is invaluable at this stage, and enables a theoretical map to show up any potential problems before installation goes ahead.

If you need some assistance with your wireless network at any stage – From Wi-Fi site surveys, wireless network design, Wi-Fi installation or help with a current Wi-Fi network – Please don’t hesitate to get in touch with us today. Our expert Wi-Fi engineers are here to help, and are still working out of our Hampshire and London bases.



COVID-19 Lockdown

As we continue to navigate this unprecedented time in our professional and personal lives, the Wi-Fi Expert blog here at Geekabit will be taking a little break.

We are following all government guidelines, and as such, we as a business like so many others are now working remotely. As many of our clients are doing the same, the need for Wi-Fi support, network design and Wi-Fi installations are all temporarily on-hold.

There are a couple of articles that we have blogged previously that could prove useful during this time – How to fix common Wi-Fi problems, and how to spot people stealing your Wi-Fi! We’ve linked these for you below.

Common Wi-Fi Problems and How to Fix Them

Who is Stealing my Wi-Fi and How Can I Block Them?

We look forward to getting back to it once all of this over. Here’s hoping that everyone reading this will have secure and reliable Wi-Fi to stay connected to colleagues, friends and family for the next couple of months.

So for now, stay safe and stay home.

The Security Risks of Free Public Wi-Fi

Public Wi-Fi is now very common-place in British cities, in fact cities all over the world. You won’t find many places that don’t offer some kind of public Wi-Fi when you’re walking through Winchester, London, Cardiff, anywhere! Consumers are willingly, and gratefully, connecting to these networks assuming that the networks are secure. Unfortunately, that assumption may well be misplaced.

Social media intelligence research has shown that these networks lull users into a false sense of security. These users assume that there are the necessary security protocols in place, but in reality they actually are not in upto 90% of cases.

Someone who intends to cause harm will find it relatively easy to gain access to all sorts of information and data that should be protected.

One of the problems lies with businesses wanting to set up their Wi-Fi themselves. A common misconception by well-meaning businesses who just want to offer their customers a good service, is that by installing a router and password protecting it will be enough to make it secure. However, when you’re handing our the password to all of your customers, you’re enabling anyone with the password and connection to access all the devices in the network. So not secure at all.

This approach is well-meaning, but unfortunately rather naive, and not one that is limited to small businesses. Even large companies and established chains have trouble with this kind of network security.

Having a default username and password for multiple end-connected devices can also cause big problems.

Imagine you walk into a cafe, you buy a coffee, and they give you the Wi-Fi password on your receipt. You sip your coffee, take your phone out of your pocket and log on to the most common web address for their router. Easy access. You could then type in the default username and password, eg. ‘admin’ and ‘password’ and bam, you’re inside their router.

This all sounds a bit malicious, and while there are undoubtedly people out there who would attempt to access private and personal data and information, it’s not just this that can cause harm.

Someone could innocently log in with their device and unwittingly share a virus from their laptop, infecting every other device on the network that have default passwords. Scary stuff.

Even more scary when you consider that upto 83% of the population have accessed their email accounts, shared media online and accessed their bank balances on public Wi-Fi services.

There are also risks from ‘man in the middle’ attacks where someone hacks into the original network, and then rebroadcasts a wireless network with the exact same name. A threat very difficult for end users to ascertain.

These users will then connect to the threat network and unbeknown to them, type in all their bank information to the wrong website.

The public are always going to want to use public Wi-Fi and even with these possible threats, people will still connect and go about their online business. Really, the responsibility of security lies with businesses themselves. They need to make the assumption that users will not necessarily be doing the right thing, or protecting their sensitive data, so the businesses need to make their networks properly secure. Self-made public Wi-Fi services through a standard router and password aren’t enough in today’s internet climate.

Coffee shops, restaurants, shopping centres, airports. There are so many public places that are offering an insecure service. Airport customers are taking huge risks according to the experts. When you were last in an airport, did you log on? Maybe you were travelling for work, so hopped on your laptop before making your way to the departure lounge.

Airport wireless networks rely on one simple check box as part of their terms and conditions, but this is more to protect them rather than the end user.

Next time you connect to a wireless network at the airport, open your network section and see how many devices are on that network. There will likely be hundreds of devices listed there, and all you need is one of those to have malicious software on it for it to cause damage.

In general, the consumers expect the utility of having access to Wi-Fi without the understanding of security issues.

That’s where your business can step up. Coming across a secure public Wi-Fi system is actually quite rare so if you’re reading this wondering if the service you are currently offering is secure enough, it’s time to let the professionals have a look.

Don’t hesitate in getting in touch with our Wi-Fi experts here at Geekabit. Operating out of Winchester, Cardiff and London, we can help your Hampshire, Wales or London based business be one of the secure few rather than the potentially threatened majority.

Who’s currently trying to keep to some New Years Resolutions? We’re over a week into January now, and most people seem to have some kind of aim they are trying to stick to.

This year the hashtag #newyearsameme seems to have been particularly prevalent, with many celebs and social media influencers opting to move away from the traditional time for new years resolutions and instead promote a focus on being happy in your own skin. No crazy diets, no impossible exercise expectations, no ‘be more this’ or ‘become less that’.

I think this is great, although I do also believe that it’s healthy to have goals and ambition, and if they are realistic and achievable then I think New Years Resolutions can be a really positive thing!

I’ve been reading all sorts of lists of resolutions on the internet in the name of research – Ideas on how to introduce exercise into your routine, how to cook healthy balanced meals, to try and read more, get fresh air and – possibly most popular – get offline. Whether that’s heading out for a walk without your phone, or actually switching off your router, the push seems to be on being online less. Many of the lists told their readers to turn the Wi-Fi off, unplug the router, turn phones on airplane mode – Basically use any means possible to get offline.

You may decide that this is the resolution for you, but here is our twist on it…
If you’re going to be making more time in your personal life to be offline, at least make sure your connection is a good one when you are connected. Especially when you are working.

Your business needs Wi-Fi to function well and unplugging your router might sound on paper like it’ll provide your employees with some zen, but it’s actually going to cause frustration and certainly not going to help business practices or keeping things going.

That’s probably a bit extreme (like you’re going to unplug your router!) but slow internet that keeps dropping out will certainly cause frustration too. Your employees will be more productive and work more efficiently if you have a fast and reliable connection.

Have your employees or co-workers been complaining about slow internet speeds? Trying to download a document but it’s taking ages? Having to call back clients while you wait for your computer to catch up?

If these things are something your business has struggled with recently, then don’t delay in getting it sorted out. Start the new year fast and fresh!
And if you’re not the boss but you’re reading this thinking YES then save the link to this blog and slide it into their DM’s…

It might be a new year and the same you, but let’s make 2019 #NewYearNewWifi

We’ve written many a blog on the benefits of Wi-Fi for your business (go on, have a scroll, we won’t tell…). Wi-Fi really is one of those tools that you really can’t afford to mess about with.

So why not give us a call and see how we can help your business in 2019 – From designing your network and installation, to fault finding and fixing, we’ve got Wi-Fi experts working out of London, Winchester and Cardiff waiting to get your business online, fast.

Christmas Lights and Wi-Fi – Our Top Tips to Stay Festively Connected

Christmas well and truly arrived in our house this week! Apparently the 1st of December was National Christmas Tree Day as well as National Christmas Lights Day – Makes sense seeing as you tend to put them up at the same time!

Which is rather fitting as my family and I also go out on the 1st December and choose our Christmas tree – We like to get a real one, and my eldest boy loves to pick it out.

So our tree stood in our living room all of Sunday and by Monday afternoon it was really crying out to be decorated. I found a Christmas playlist on Spotify (‘Christmas is Coming’ – Check it out, you won’t be disappointed) and fought the knot of tree lights to get them on the tree and twinkling.

But as soon as I turned them on, Buble started buffering and it made me remember an article from last year that said how Christmas tree lights could affect your Wi-Fi!

I think in my case it had less to do with the tree lights, and more to do with the fact that I had 3 devices running off my router – My phone playing Spotify through my Bluetooth speaker, my laptop on in the corner of the room, and my smart tv turning the screen into a log fireplace through Amazon Prime Video. Festive? Yes! Wi-Fi consuming? Oh yes!

This potential issue with Christmas lights pops up every year though and it’s worth mentioning again just to prevent any interference happening. No one wants to choose between functioning Wi-Fi and a Christmassy home do they!

So, could Christmas tree lights really affect my Wi-Fi? Here’s the science bit…

Christmas lights emit a very weak electromagnetic field which can theoretically interfere with the radio waves being transmitted from your router, thus affecting your Wi-Fi speed. If the lights were to transmit electromagnetic radiation at or around the same frequency, then yes, they could slow down your Wi-Fi.

Between the LED or lamp being completely on or off, it can exhibit negative resistance which in turn causes radio energy. This happens less with modern day lights than older ones though (see below for more info on this).

Is your tree lit up to give a soft glow, or does it look like something fresh out of Blackpool illuminations? The more lights you have, the stronger the electromagnetic field will be.

And closer the router is to the lights, the higher the chance of interference.

Here are our top tips to stay festively connected…


Rule #1 – Don’t place things on top of your router

Just don’t do it. This doesn’t just go for decorations, but in general.

Don’t put Christmas lights or anything else directly on top of, or too close to, your router. I can’t personally see the appeal of adorning it with twinkly lights or putting decorations on top of it but each to their own.

While it has been reported that routers that were placed too close to Christmas tree lights could be negatively affected by signal interference, if they’re not directly next to each other or on top of each other, it should be fine.


Rule #2 – Use a main plug socket

Christmas is one of those times of year when you’re struggling for socket space and digging out all the extension cables you can find to be able to power Christmas tree lights and all kinds of other lit decorations.

But don’t be tempted to unplug the router and plug it into the extension. It will work a lot better, and faster, if it’s plugged into a main socket.


Rule #3 – The more modern the lights, the better

There are generally 2 types of light whose qualities have the potential to cause interference.

Older types of Christmas lights that are arranged in a string of low voltage lamps in series with each other and are designed to blink can cause radio interference which can lead to dips in Wi-Fi speed.

More modern Christmas lights use solid-state LED’s and have an external control for flashing which don’t create radio noise. However, it’s worth noting that some LED’s have a chip inside the bulb to control the blink and these devices can also cause interfence.

On the whole though, modern lights are definitely less likely to cause you a Wi-Fi problem, so maybe save yourself the annual horror of trying to untangle your 10 year old string of lights and treat yourself to some new ones.


Rule #4 – Don’t put your router in ‘high traffic’ areas

Tis the season for family gatherings, friend get-togethers and all sorts of festive shenanigans. Not to mention the big man in red tumbling down the chimney! Humans are great signal absorbers, so put the router in a place where it won’t get blocked by partying people or round bellies that shake like jelly.


If you’re Wi-Fi geeks like us, and your tree isn’t up yet, why not do a little experiment? Test your Wi-Fi and download speeds before and after putting up the Christmas tree with the lights turned on. We’re pretty sure the results will be rather negligible – But let us know your results!

What’s The Worst Excuse for Bad Wi-Fi You’ve ever Heard?

When you get home from a lovely week away, ready to catch up with emails and get back to work only to find that your internet is out… Nightmare!

We went to Devon for a week, which was lovely. In-keeping with our digital detox from the other week, our beautiful little countryside cottage had awful Wi-Fi which nudged me in the direction of avoiding social media, which turned out to be rather refreshing.

However, once home, I was keen to get back online – Yes to share a few photos, but also to get back in the zone of work before Monday arrived.

So I switched on my laptop, connected to the router, but no web pages were opening. The Slack app wasn’t letting me read my messages on my phone. No online video streaming on the TV to distract the kids!

What was going on?

I sent a text to both my neighbours – One was fine, but the other had had no phone line or broadband earlier in the week either.

Time to contact our broadband provider. After a few text messages, it transpired there was a fault on our line and they would have to send an engineer out. This would hopefully be within 72 hours but could take up to 5 days. Of course, this was Friday afternoon, and of course, the 72 hours doesn’t include the weekend. Time to text the boss.

Thankfully the engineer arrived on Monday morning and fixed the issue.

And the problem? Rats! Apparently rats had gnawed through the cables and they had to be replaced.

I work from home most of the time so it’s pretty important that I have a reliable internet connection. Didn’t think I’d be getting back from holiday and straight away having to tell the boss that I couldn’t get online because of rats chewing cables. It’s a bit “The dog ate my homework, miss” isn’t it?!

Anyone else had a rodent related outage? What’s the worst reason for bad Wi-Fi you’ve heard? Or used?? We’d love to hear them.

Here at Geekabit, we can’t control rats getting in to external cabling, but we can do a lot of other things to help improve your Wi-Fi. Check out our website and see what we can do for you and your business.

What lengths would you go to, to improve your Wi-Fi speed?

Here at Geekabit we’ve always had a bit of a soft spot for Wales, and now even more so with the boss recently making his beautiful Welsh lady his wife. So when we came across an article about the residents of Michaelston-y-Fedw digging a 15 mile long trench in order to be able to lay super-fast cables, it really made us smile.

The Welsh residents of this small village just a stones throw from our Cardiff based office, were desperate for faster Wi-Fi (aren’t we all, sometimes?) and took matters into their own hands.

With a population of just 300, it’s probably not at the top of service providers list for super-fast cabling, but that doesn’t mean that these villagers weren’t as exasperated as the rest of us when it comes to slow Wi-Fi.

They described their internet connection as feeble, and so decided to dig the trench needed for fibre broadband cables themselves.
It took thousands of volunteer hours from farmers, teachers and retired people from the tiny Welsh village – A huge community effort, which has resulted in the first households being connected successfully. By the Autumn, 90% of homes in the village should be enjoying a massive improvement in internet speed, having gone from 4Mbps to 1000.

Like so many grand schemes, the original plans were hatched in the local pub. Landlord Ben Longman had recently paid for high speed broadband before realising that it wouldn’t work.

With the whole community seemingly disgruntled with the poor Wi-Fi, they went on to set up a community interest company and secured a Welsh government grant.

It was decided that costs for each household should be kept to an absolute minimum so the villagers rallied together to complete as much of the work as possible themselves. While some of the work was completed by local farm workers who were hired to help with the dig, much of the digging efforts was completed by villagers who excavated trenches from their home perimeter and up to the external wall where the fibre needed to enter their home.

It’s an incredible community achievement, with organisers commenting that they almost couldn’t believe what they had managed to do when they all came together.

It now takes less than a minute to download a film, when it used to take a few days. Imagine settling down to watch a movie, only to have to wait until the following night!

One of the men, and husband to one of the organisers who helped with the project was 71 year old Jum Dunk who had lived in the village for over 4 decades. Taking part in the dig led to him making new friends that he hadn’t met before – It might be a small Welsh village, but the initiative brought together people from all different walks of life that may not have had the opportunity to meet.

And if you’re thinking that fast Wi-Fi isn’t quite enough of a reward for digging a 15 mile trench, you’ll be pleased to know that each household that applied before 30 April were connected free of charge with their first year’s service also free.

Here at Geekabit we are so community minded, and just love hearing of success stories like this where people show what can be achieved when we come together. And even better when it’s in our own field too.
