How do I change the wireless channel on a Technicolor TG589vac v2 router?

Written by KCOM Support on 23/03/2022. Posted in Broadband.

Your router can broadcast on different wireless channels. If your neighbour's router is using the same channel as you, this can interfere with your signal and cause some problems.

Changing the wireless channel on your router may help improve your wireless connection. For more tips on getting the best out of your connection, see our guide.

Something you need to know about your router

Your Technicolor router is dual band which means that it two wireless frequencies for your devices to connect to: 2.4GHz and 5GHz.

You can tell which is which by looking at the name. The 2.4G network has the regular wireless network name and the 5G network has 5G on the end of it. Here's an example:

5G Network

We strongly recommend connecting to the 5G network where possible as this provides a stronger signal and you're less likely to have issues.

If you can't connect to the 5G network on your devices, or you're too far away from the router, you can connect to the regular wireless network.

Changing the channel for 2.4GHz or 5GHz

The 5GHz network on this router will choose the best channel for you automatically and therefore changing the channel isn't recommended, however you can find instructions to change the channel for both the 2.4GHz and 5GHz networks below.

You should only change the channel for the network that you're having trouble with (e.g: if devices connected to 2.4G are disconnecting, but devices connecting to 5G aren't).

  1. Connect a device to your Technicolor router using an Ethernet cable (recommended) or Wi-Fi.

    Connect to Ethernet or Wi-Fi
  2. Open a new web browser and type into your address bar and press enter or go

  3. You should now see a Technicolor screen with a number of different tiles. Select Sign In at the top right.

  4. Type in your username and password to sign in. The username will be admin and the password will be what you set it to when you first ever logged into the router.

    If you're logging into the router for the first time, the password will be admin or the access key on the bottom left of the label on the back of your router.

    Select Sign in.

    Having trouble logging in?

    It's possible your password is your Access Key, this can be found on a sticker underneath your router. If you've changed your password but can't remember it, you'll need to factory reset your router.

  5. Select the Wireless tile.

  6. Next, select the network name under either the Access Points 2.4GHz or Access Points 5GHz headings.

  7. Find the setting called Channel. This will usually be set to auto as your router will try to automatically switch to a channel with less interference.

    Your Wi-Fi can be affected by other routers working on the same frequency, so if you're changing the channels for 2.4GHz, we'd recommend trying channels 1, 6 or 11 to begin with. If you're changing the channels for 5GHz, work your way upwards in fours from 36 (40, 44, 48, etc).

    If you continue to have problems, work your way through the channels one by one. Some devices (especially in the UK) don't work with channels 12 and 13 on 2.4GHz, or higher channels (50 or above) on 5GHz, so it might be worth skipping those channels.

    5GHz isn't as congested as 2.4GHz, so it's usually easier to find a channel that works - however the range of 5GHz doesn't extend as far as 2.4GHz.

    Please bear in mind that you may not notice an immediate difference and so you may need to try each channel for at least 15-20 minutes. It's also worth noting that the Speed value (that you can see above the Channel setting) will change depending on the quality of the signal being broadcast by your router.

  8. Once you've chosen a channel, select Save at the bottom to apply your changes.

    To see if your wireless connection is now working, use the internet as you normally would. If you find you're still having the occasional issue, you may need to change your channel again.
