"MY broadband is really slow. What can I do to speed it up?"

When loading a page feels like the final scene of Chariots of Fire, you probably have a broadband speed problem.

If you're sick of hearing that the easiest way to improve your broadband speeds would be to just pack up and move then this guide is for you.

We've complied a list of the simple (and the not so simple) things you can do to improve your broadband speeds.

If you're looking for more information on why and how much factors including distance from the exchange and fair use policies affect the speeds you receive please see our guide to broadband speeds.

But for practical help, from quick tips to longer projects, carry on reading.

Five very quick tips

1. Fiddle with your router

Time needed: 30 minutes to an hour

Often, it's the signal provided by your wireless router - rather than line or provider problems - that are slowing your broadband down.

Fiddling about with your wireless router could improve the signal that you're getting and make your broadband faster.

First, try physically moving your wireless router to get a better signal. The signal can be disrupted by other devices which operate in the same 2.4GHz range as your router so moving the router away from microwave ovens, Bluetooth devices, baby monitors and cordless phones could make your broadband faster.

Signal can also bounce off shiny surfaces, which is why people with faster broadband tend to have poorly applied makeup.

Also be aware that signal will be weaker after it has gone through walls and objects, a direct line of sight is best but not exactly achievable throughout a home. Minimising walls/objects as much as possible is the next best thing.

It may also be worth checking the instructions that came with your router (if you've lost them many are available online, try Googling the model name and number) to troubleshoot common problems that could be affecting your broadband speeds.

Finally, it is worth noting though that both the router sending the signal and the device inside the computer or laptop receiving the signal play a part.

Often you can get external aerials for laptops for example which can pick up weaker signals in comparison to embedded receivers.

Apple laptops for example are common culprits as the aluminium frame of the laptop itself can cause signal deflection which results in poorer reception (similar to the well known iPhone 4 reception issue).

Note also that at this stage it's worth double checking the security settings of your wireless router to make sure your broadband connection isn't being piggy backed. See more on how to do that in this guide.

2. Plug it in

Time needed: 10 minutes

Ultimately, plugging in an Ethernet cable is the only way to dodge wireless signal degradation entirely.

Wireless signal is poor by its very nature: network analyst Epitiro, conducted over 1 million tests which showed that on average broadband connections shared using home wi-fi networks were 30% slower than the speeds measured at the main phone socket in the same property.

That equates to around 15-20Mb for someone paying for a 50Mb broadband connection.

3. Compare your broadband package

Time needed: 10 to 30 minutes

It could be that your broadband package is no longer suited to how you're using the internet.

If you've had your current broadband package for a number of years, for example, it might just be that speeds that were adequate to load basic web pages a few years ago are no longer good enough to cope with your new BBC iPlayer and WoW addiction.

Our fastest broadband guide has more information on the fastest broadband providers available to individual households through a postcode or phone number search with the fastest advertised speeds at the top of the table.

4. Look into your usage

Time needed: 30+ minutes

Some broadband providers prioritise certain types of internet use so look into how you're using your broadband connection.

If you download a lot from the internet and you're finding that your broadband is very slow your provider may be throttling your connection under the terms of their fair use policy. See our guide here on broadband fair use policies to see if this might apply to you.

If you often use the internet at peak times - around 6pm - 9pm - try testing the speed at off-peak times, for example in the morning, to see if that makes a significant difference.

Unfortunately, if you find that the way that you use your broadband is having a negative effect on your speeds there is little you can do except switch to another broadband provider with a fair use policy better suited to your needs - this table is a good place to start.

It's also worth being aware however, that it's possible that too many people can be signed up in one area to the same provider, which can affect your broadband speeds even if you consider yourself to be a very light Internet user.

Too many users like this is known as high contention, where customers are effectively sharing bandwidth and causing bottlenecks at peak times when everyone starts trying to catch up on EastEnders at the same time.

The easiest way to spot this is if you know for sure your usage is low and your broadband grinds to a daily halt around tea time.

Although if it is high contention causing your slow broadband, there's little you can do but pick up sticks and try another ISP.

5. Check your microfilter/splitter

Time needed: 30+ minutes

If you have an ADSL connection your broadband provider should have provided you with a microfilter (also known as a broadband filter or splitter) when you signed up.

It's a little white box which plugs into your phone socket and makes sure that the ADSL and phone signals are completely separate. If you don't have a microfilter, or it's not installed correctly or is broken, you'll probably get interference on your phone line and reduced broadband performance.

Here are the four main things to check:

If you can, it's also worth plugging the microfilter for your broadband router into the BT master socket - the first socket in your house where the telephone line comes in from outside.

The reason for doing this is any secondary sockets will be using additional internal wiring and connections which could have their own faults.

Two longer projects

1. Buy a better router

Time needed: 2hrs+

If you have fiddled with your router and haven't seen a significant improvement then you might get faster broadband with a better quality router.

Most of the wireless routers that are given away free with broadband packages are very basic and many of the broadband packages that advertise higher speeds do so, at least in part, because they are giving away better equipment.

If you have a high-speed broadband connection but an old router your router might not be powerful enough for your broadband connection.

A wireless router that uses an 802.11b/g network protocol (the most common type) will support speeds up to 11Mbps if it only supports 802.11b and up to 54Mbps if it supports 802.11g. However, even if it supports up to 54Mbps - this speed will reduce on distance and even more so for every wall or object it has to pass through to reach your computer or laptop.

To get the fastest broadband you'll need a router which is 802.11n compatible - it supports speeds up to 300Mbps and most importantly has an increased range of 70 meters (compared to 45 for 802.11b/g).

For example, Virgin Media's XXL broadband and TalkTalk's Pro package both come with a good quality Netgear wireless 'N' router which is 802.11n-compatible.

However, it's worth bearing in mind that an 802.11n router will only show any improvement if you also upgrade the receiving wireless card in your computer or laptop - otherwise the 'n' router will fall back to using 802.11b/g.

Warning! Although most ISPs are more than happy to let you know your broadband username and password, which you'll need to use your router, Sky Broadband won't give you any technical support unless you're using the router that they provided you with at the start of your contract and could suspend your service if they find you using your own router.

It's also worth noting that other ISPs will find it difficult to provide technical support to you if you have you own router, since their staff will be trained on the routers that come free with their broadband packages.

Customers of BT, Sky, TalkTalk or Virgin Media may want to look into the newer hub routers that are now being provided.

We've covered them in more detail here, but they are promoted as offering better wireless signal and coverage, for example some can even automatically detect interference and switch to a different channel to keep speeds from degrading.

2. Switch your broadband provider

Time needed: 2 days

By moving to a different broadband provider you can often improve your speeds massively.

Use one of our broadband comparison tables to see which companies are offering the fastest speeds in your area and read our reviews or guide to this subject for an idea on how realistic that headline speed is.

See the 'switch your broadband' guide, available here, for more information on the practical aspects of moving, especially if you're in the middle of a contract.

Finally, it's good to talk, email, text and tweet, especially when you're thinking of moving: if you think that you're not getting a reasonable broadband speed then get in touch with your broadband provider and ask them what they can do to make your broadband faster.

Too many links in the chain. Question: if I only get a 2meg speed to the cottage (I am rural) will a better router "boost" that? (Like"upscaling" on a dvd player) I use tp link plugs, rated at 500 mpbs. BUT given I only get 2mbps in the first place could I have used the 300 mpbs Tp link plugs? Or IS it better to have 500, so that at least the signals from router to computer are 500mbps??

I don't pay for my internet every week to "fiddle" with my router. I pay and I demand what was promised to be granted for this money. Damn you Sky.

I know the feeling, Sky is a rip off

How about uhm I don't know switch provider

Is there a device like an antennae or something which can attract better signals?

Interesting, but shiny make up affects signal? Surely shome mishtake!

He means the make up is bad because there would be less mirrors to do your makeup in.

Thanks for giving the information.

Thanks for the information, modems and routers should be switched off regularly after use.

7 October 2016

No I am qualified in IT, networking is a sinch for me too. Modems and routers should remain on, its the supplier that should be looked into turning a modem off or a router stop's the direct flow of transmission to the terminal. What you should be looking at is the setting on your machine for the adapter flow control should be disabled, you will see rx and tx service in here as this is the receive and transmission settings.

Hi David,

Actually many ISPs now advise against turning the router off wherever possible as it can cause a signal to the broadband provider that the line is unstable and they sometimes reduce speeds on the line as a result. So you should leave the router turned on as much as possible.
