Do UK Trains Have the Slowest Wi-Fi Speeds in Europe?

It has been found that trains in the United Kingdom deliver some of the slowest internet speeds across Europe. 

Ookla, the network testing company, analysed the Wi-Fi performance onboard train services across Europe and some Asian rail networks using their favoured service Speedtest.net by collecting data via consumers themselves. Results suggested that the UK does indeed deliver some of the slowest Wi-Fi speeds available on trains in Europe.  

If you’ve ever tried to work on your train commute or while away the time by streaming a show using train Wi-Fi then you will likely already know that Wi-Fi quality across UK rail operators and networks is not particularly strong, consistent or reliable. 

What Are the UK Government’s Plans for Rail Network Connectivity Improvements?

Back in 2017 the government at the time pledged to improve connectivity on mainline train routes by this year, with the aim to provide Wi-Fi and mobile speeds (5G) of up to 1 Gbps. While this may be true of a few rail operators, for most this outcome has not been reached. 

This issue has recently been revisited by the current government as part of their Infrastructure Strategy for the next 10 years, which was published back in June. This strategy includes a commitment of £41m to “introduce low-earth-orbit satellite connectivity on all mainline trains, significantly improving both the availability and internet data connection speeds for Wi-Fi connected passengers“. However, there doesn’t seem to be a clear date as to when this will be delivered.

Which Country in Europe Has the Best Onboard Wi-Fi When Travelling by Train?

According to the data collected by Ookla, there seems to be quite a gap between the best European train operators for onboard Wi-Fi performance and the worst. 

From data taken during the second quarter of 2025, the countries with the top 3 fastest onboard train Wi-Fi were Sweden, Switzerland and Ireland in terms of the median average download speed (64.58 Mbps, 29.79 Mbps and 26.33 Mbps respectively. 

At the other end of the scale, with the slowest on board speeds were Spain, the UK and last of all the Netherlands with median average download speeds of 1.45 Mbps, 1.09 Mbps and 0.41 Mbps respectively. 

So while the UK doesn’t have the absolute slowest onboard train Wi-Fi in Europe, it wasn’t far off. 

The countries with the best upload speeds were similar. You can see how other European countries fared in the graph imagery below for both download and upload speeds, with thanks from Speedest Intelligence. 

Will the UK Rail Network Catch Up With Current Wi-Fi Standards?

If you’re a regular reader of our Geekabit blog, you’ll have seen us talking about Wi-Fi 8 and the advancements this new Wi-Fi standard will be making when it arrives.  

Unfortunately, many rail operators aren’t up to date with Wi-Fi standards and are still using Wi-Fi 4 based connectivity which could be a big part of the problem. Not only this, but 38% are also still using the 2.4 GHz band which is the slowest and most congested. 

Interestingly however, even countries who are embracing more modern Wi-Fi options like using the 5 GHz band are also still underperforming on speed (this can be seen in the likes of Spain and Italy’s speed scores). This could be due to poor satellite or trackside infrastructure causing a lack of pace in backhaul capacity. This is a key factor for onboard performance. 

What Are The Key Factors Affecting Onboard Rail Wi-Fi Speeds?

There seem to be many contributing factors to what causes issues with Wi-Fi speeds across European and Asian rail networks. These include:

  • Construction materials used in train carries
  • Onboard network design
  • Political leadership and policy
  • Adoption of satellite broadband connectivity from LEO satellites

Whilst it’s great that the UK has listed Low Earth Orbit satellites in their Infrastructure Strategy as part of improving connectivity on rail networks, it’s still not going to improve Wi-Fi in tunnels!

‘Where is the best place to put my Wi-Fi router?’

Is your Wi-Fi router in the wrong place? 

If you’re having issues with your Wi-Fi and can’t figure out what the problem is, one potential problem could be where your router is in your home. 

You would be surprised how many people have their Wi-Fi router somewhere that could cause slow Wi-Fi, internet blackspots and maybe even no connection whatsoever! 

Is your Wi-Fi router in one of these 3 worst places? 

When the internet isn’t working properly, it’s really noticeable. Like when there’s a power cut or no hot water – We’re all very used to this utility just always being there in the background.

And when it’s not working properly, it’s hugely frustrating. Whether you’re on a Zoom call for work and the screen keeps freezing, or you’re trying to binge watch your favourite Netflix show and it keeps buffering in the best bits – Slow, unreliable internet can make things stressful. 

But what if your dodgy connection is purely down to the location of your Wi-Fi router? If that’s the case then you’re in luck – It’s an easy fix! 

These are some of the worst places to put your router that could be suppressing your internet signal:

In the kitchen

The kitchen is full of appliances that could cause interference to your Wi-Fi like the microwave, so it’s a big no-no to place your router in this room. Things made of metal or containing water can cause significant issues with Wi-Fi signal, and you’re likely to find lots of these offending items in the kitchen area. 

Too low down

Putting your router too low down means that the signal it’s transmitting may not reach users’ devices effectively. 

Cramped space

Be honest – Is your router tucked away somewhere, like a cupboard or hidden behind things? We do understand that routers aren’t always the prettiest of things, and might be in-keeping with the design aesthetic of your home. But hiding it away in a cupboard or burying it under other things could well be the cause of your Wi-Fi woes. 

Where should I put my Wi-Fi router?

We’ve told you where not to put it – Let’s take a look at where your Wi-Fi router is going to work to the best of its ability. 

Place your router in a central location, out in the open 

Consider which room(s) you use the internet the most, or where you need the connection to be the strongest. If you work from home, do you have a home office? Where do you stream films or TV shows? Do you have online gamers in your home? 

The general rule of thumb is to place your router somewhere central to your home in an open space – That way you’ll stand the best chance of your Wi-Fi signal spreading throughout your home and reaching everywhere you need it to go. The further away you are from the router, the more signal strength is lost.

If your home office is outside at the bottom of the garden and getting the Wi-Fi out there is a bit of a stretch, you might like to have a read of our blog ‘How do I get Wi-Fi in my garden?’ which we wrote back in lockdown. 

Place your router high up 

You’ll find that your Wi-Fi signal is better the higher up your router is. If possible, install your router approximately 5- 7 feet off the ground. 

Somewhere like a high shelf could work well – But remember it needs to be plugged in and should also be away from windows. 

Your router emits signal out and down, so placing it up high should improve your signal range. 

Place your router away from thick building materials like brick, plywood and sheetrock

Certain types of building material like brick, plywood and sheetrock can hinder your Wi-Fi if you place your router too close to them. Try and avoid putting your router in a location where these materials could cause interference. 

Utilise available hardware and software

If, despite your best efforts, your Wi-Fi still isn’t quite reaching one area of your house then you could consider getting a booster to help you out. 

Also make sure that you keep up to date with software updates so your router is able to work at its optimum effectiveness.

Keep your Wi-Fi secure

Is your Wi-Fi password protected? Don’t just let all your neighbours and anyone passing by gain access to your Wi-Fi. Not only does this put your personal data at risk, it will also make everything slower! 

The more devices that are connected to your router, the slower the connection will be. Odds are you’ve already got a multitude of connected devices in your home as it is – You don’t need the neighbours’ devices too!
