Changing channels on router?

wJanet1 — Wed, 21 Jan 2026 13:44:15 GMT

Good afternoon,

Hope someone can help. After a few problems with my system which is a bit better, I'm now having trouble streaming programmes, from late afternoon and at night it's impossible. the same with my internet very slow. I did a speed test on my account, they said it was really slow and reset my router, sadly it has not solved the problem. I did a wi-fi analyser that scans what channel people are using, mainly channels 1,6,11 is there another channel i could use on 2.4 gh without losing connection as it's really busy and it was thought that's what's slowing everything down.

Thankyou

wJanet1

Hi there @wJanet1, I'm really sorry about the issue you are having. The streaming must be affected by the slow speeds which we are going to look into. Please confirm if you are currently at home. Thanks

No worries

Hi @wJanet1

Within the 2.4GHz band, you should only ever use channels 1, 6 or 11 as they are classed as the only non-overlapping channels. The 5GHz band is different & has more channels available. Please can you PM me (to preserve your privacy) the screenshots from your WiFi analyser? Not knowing which one you are using, I need to see:-

The AP view
2.4GHz channels
5GHz channels
Signal strength/time graph, where it has run for 5 minutes before taking the screenshots.

Please can you try & use a PC to upload these screenshots, otherwise they will be over-compressed & too small to read. The best way to do this is via the Insert Photos tool in the PMs editor, set the Size parameter to Large.

The information below is provided by TalkTalk. For confirmation, please contact @Lorrainef, the manager of the TalkTalk support staff on this forum.

Hi @Mandisa-TT

The customer will hopefully send me screenshots from her WiFi Analyser over the weekend. Then I will report back on my findings.

Thank you so much for the update @KeithFrench

Hi @Mandisa-TT

I have received some screenshots, but there are three missing. Due to problems with the forum software, I had to give the customer my email address, which I did not want to do.

@KeithFrench I am sorry to hear that; I will escalate this to my TL.

Hi @Mandisa-TT

Hopefully, the customer now has a working WiFi analyser and I will post back when I see screenshots from it.
