Changing channels on router?

[wJanet1]

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

Thank you so much @KeithFrench.

If your 2.4GHz channel keeps switching, this is usually caused by Wi‑Fi Optimisation, which can automatically move the router to a different channel even after you’ve set it manually.

Hi @wJanet1 

Alas, with the two networks on channels 3 & 13, your 2.4GHz band is likely to cause WiFi Optimisation to keep trying different channels and never be much good. Try to get as many devices as possible using the 5GHz band.

Hi Keith,

Just to say thanks very much for your help, although I changed the 2.4ghz yesturday to channel 6, but today it was on another channel? I changed it again, sadly the security channel which was on no 13 is still on that number.

thanks

Hi @wJanet1 

Thanks for the update, and I'm glad to hear you were able to make the change Keith recommended.

Hi,

I managed to change the channel keith french advised me on, the 5ghz was fine but today when looking what channel the 2.4ghz was on it had changed to another channel? so I've changed it back to 6.

Thanks

@KeithFrench 

Thanks so much for taking the time to look into this and for breaking everything down so clearly.

@wJanet1

Please go ahead and check the router settings as suggested. Let us know how it goes.

@KeithFrench 

Thanks again for your support

Hi @Mandisa-TT 

These are the results of my analysis of the Wi-Fi network of the customer, @wJanet1 

There are two routers using channels that they shouldn't be (only channels 1, 6 or 11 can be used in the 2.4GHz band):-

• Channel 3
• Channel 13

These two networks will permanently interfere with either your Sagemcom F@ST5364 0r 266 WiFi Booster. At the time of your screenshots, your Sagemcom mesh was using channels 1 & 11. Currently, channel 3 interferes with channel 1 (and any others on channel 6) and channel 13 interferes with channel 11. 

Whilst Wi-Fi Optimisation will try to get you a better channel, there simply isn't one. Unless you know who these two networks belong to, there is nothing you can do.

Your 5GHz band might be able to be improved as well, by a configuration change in the router. This is to do with channel bandwidth. Your PC is only using 20MHz bandwidth, where it should be using 80MHz. This can slow you down. The router is normally set to Auto for the 5GHz band and your PC, upon connection to the Sagemcom mesh network, will negotiate the highest bandwidth possible. As your WiFi card in your PC supports Wi-Fi 5 (802.11ac), it should support 80MHz.

To check this, log into the router & go to:-

Dashboard > See Wi-Fi Settings > Manage Advanced Settings > Wi-Fi 5Ghz gear icon > Advanced

Make sure that the Bandwidth option is set to Auto.

Hi @Thabile-TT 

I now have enough information from @wJanet1 with regards to the WiFi analyser. I hope to work on this tomorrow morning.

[Thabile-TT]

 @KeithFrench thanks for the update, it seems that the issue has been resolved @wJanet1 please do let us know how it is going.

Hi @Mandisa-TT 

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

[amahle-TT]

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

[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.

[Mandisa-TT]

Thank you so much for the update @KeithFrench 

[KeithFrench]

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.

[Mandisa-TT]

Thanks @KeithFrench

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.

Hi Keith,

I'd be very grateful if you could help. I got the last problem sorted from your advice, now this one's cropped up. I will try and pick up answer either tonight or tomorrow if that's ok.

cheers
