How to troubleshoot TalkTalk broadband internet speed

TalkTalk Internet speedtest - Slow Internet speedBefore starting to troubleshoot the speed of your TalkTalk broadband connection, you firstly need to run the TalkTalk Internet Broadband Speed Test and also confirm the exact Upload and Download speed that you are paying for.

You can get this info by checking a TalkTalk bill or contact TalkTalk to confirm this info.

Possible causes of TalkTalk slow broadband speed

Is it your TalkTalk broadband that is slow or is it your device (PC/laptop/phone)?

You need to consider how many applications are concurrently running on your device that could be utilising your system resources (mainly RAM memory and CPU) and/or your TalkTalk internet bandwidth.

If you’re on a laptop then you can use the task manager to see your processor and memory usage.

On any other device you could try rebooting the device which should hopefully shut down all applications that may have been running in the background.

Re-run the TalkTalk speed test on your personal computer and your mobile to see how the speedtest results compare between the 2 devices.

This should hopefully give you some info to work with in terms of whether the problem lies with your device or the TalkTalk broadband connection.

Is your wireless connection the problem?

The cause of the issue could be your Wi-Fi network connection and not the TalkTalk broadband internet connection.

You can rule out the Wifi network network being the cause of the problem by connecting your computer directly into the TalkTalk broadband router using an ethernet cable and run the TalkTalk speedtest again.

If the speed is better when you’re connected using an ethernet cable then this proves that the problem may be with your wireless network connection setup.

Possible things to investigate are:

  • Are the WiFi channels you’re using for your wireless network (SSID) overlapping with the neighbors?
  • Could the wireless network signal from the router be obstructed?
  • Does the performance improve when you’re stood directly infront of the TalkTalk broadband or wireless router?

Who is connected to my Wifi network?

Have you checked that your wireless network password has not been compromised? Do you have an un-secured Guest wireless network?

Neighbors could be using your Wifii network and using up all the TalkTalk bandwidth downloading/uploading or even streaming netflix! Worse than that, they could be carrying out illegal activities which will all lead to your connection.

There are two apps that you can use to scan your Wi-Fi network to see who’s connected:

Both applications will scan your Wi-Fi network and display a list of the connected devices.

Do I need a Wifi network Booster for my TalkTalk broadband?

If you find that you have Wifi black holes in your home, then a Wifi extender also know as a Wifi Booster is the fix to boost your signal. They are readily available online from around £15.

The Wi-Fi network booster simply picks up the existing wireless network signal just as it is becoming weak and then re-transmits the wireless signal at a more stronger rate to extend it’s coverage.

Place the Wi-Fi network booster/extender where your Wifi signal from the TalkTalk broadband router is starting to become weak.  Approxiametly where your Wifi network signal drops down to 2 bars. Use your mobile phone to determine where this is.

When was the last time you upgraded your TalkTalk broadband router?

The TalkTalk and openreach infrastructure is constantly being updates to support new features (some customer facing and others internal).  Always ensure that your TalkTalk broadband router has the most up to date software.

The majority of TalkTalk broadband routers will allow you to carry out the software update by logging on the TalkTalk broadband router and simply clicking a button to perform the update.

If you cannot do this, contact TalkTalk and they will be able to either do this for you or guide you through how to do it depending on the TalkTalk router model you have.

In addition to updating the software, if you have had the same router for a long period, it’s worth talking to TalkTalk to ask for a router upgrade.

Is the problem external (at the exchange)?

This is probably the most common reason for TalkTalk broadband performance problem in your home and it’s more common for broadband connections that are delivered through phone lines.

If you’re not sure if this is applicable to you, you should contact TalkTalk who should be able to carry out the appropriate connection tests to check if there is a fault on the TalkTalk internet connection.

Is it due to TalkTalk Internet congestion?

If you’re finding that the TalkTalk internet connection speed in your area is slow during certain times e.g over weekends and during the evening, it may be because of congestion during peak times.

You should speak to your TalkTalk to understand if the service you have subscribed to has a minimum speed or is  a contended ‘first come first serve’ service with no minimum speed guaranteed.

Re-testing your TalkTalk broadband connection

After the fault has been resolved either by yourself or TalkTalk, retest your internet connection using  at least 2 independent speedtests such as the one here and Ookla internet speedtester to ensure the issue is resolved.
