5G WiFi unreliability last few weeks Feb-Mar '23

mistersharpe — Mon, 06 Mar 2023 21:17:43 GMT

Can you advise when the last firmware upgrade was applied?

I noticed now there are hidden guest networks which weren't there before which implies there has been one. Current version: SG4K100158

The reason I ask is because about 3 to 5 times a day the Wi-Fi network drops. Both myself and wife work from home and our laptops and phones disconnect simultaneously. Whilst devices that are connected via ethernet remain online. It reconnects almost immediately but is enough to drop our VPN connections to work.

Workstations have not moved locations and neither has the router. The only thing I can think of is that the firmware has introduced this new issue.

Also the age-old issue of the 5G network channel resetting to the default has arisen again. For me, my property is very elevated and receives interference from several other networks on the default channel when this occurs.

Any advice or ideas on resolving this issue would be greatly received. It may be that both of this issues are one in the same.

Thanks,

Carl.

Hi @mistersharpe,

Have you ever asked for the 'Wi-Fi Optimisation' to be turned off on your router ?, doing that will ensure that the router does not change Wi-Fi channel by itself, and will stay on whatever channel you manually set.

If you have ever asked for this to be turned off (to help with your wireless stability) then a firmware upgrade will cause that setting to get turned back on again, and the router would then start trying to switch you to the best channel it can, but this can sometimes cause problems in itself, as constant channel switching can cause your connections to drop.

So if you would like the support team here to turn off your Wi-Fi optimisation then they could certainly do that for you.

It is likely you have had a firmware update recently, as the firmware you are on has only recently been released.

Ah yes, this was the fix last time this happened.

Lovely support people, please disable this "optimisation" setting for me.

The support team here should be able to disable Wi-Fi Optimisation when they are back tomorrow.

A firmware upgrade, or a factory reset of the router, will usually turn this setting back on, so you would need to ask for it to be turned off again if either of those events happen in future.

optimisation is now off for you.

Morning Karl,

Thanks for the setting that. I'll report back if it sticks after I return from the school run.

I have since discovered another issue this morning, also.

No channel above 108 works. The SSID never appears - is this something you are aware of?

Carl.

I'm not aware of this, unless this is from DFS channel selection during scan.

Karl.

It used to work prior to the last update. And from what I know, I'm not near any military bases either.

Something you can escalate to next level support?

Carl.

try a pin reset of the router - hold a pin or paperclip in the reset hole at the back for 10 seconds and this will fully reset the router.

Then see if it still shows this behaviour.

Karl.

I have quite a few custom settings ie: ports/WiFi etc, if I save/reboot/reapply the config, will that work without issues?

PS: The new channel selection has held - so thank you for that! I assume that's still not a customer accessible function?

Hi mistersharpe

Only TalkTalk staff can switch the WIFI optimisation off.

Thanks

Debbie

Hi team,

I need to re-active this thread as it's happened again. The WiFI channel insists on changing back to 36 on 5GHz after a few hours when I set it to something else. How it thinks this channel is optimal is beyond me, as there's another 8 networks on the same frequency.

Can I please request this automated process be disabled again?

Thanks,
Carl.

Hi @mistersharpe

The WIFI optimisation is still showing as switched off (we cannot switch this off again going forward if it activates again)

Have you tried a router reboot?

Re: 5G WiFi unreliability last few weeks Feb-Mar '23

mistersharpe — Fri, 14 Jun 2024 12:42:34 GMT

To clarify, you cannot turn this feature off it it activates again?

I haven't tried a reboot, but shall do.

Re: 5G WiFi unreliability last few weeks Feb-Mar '23

Debbie-TalkTalk — Fri, 14 Jun 2024 12:46:35 GMT

Hi @mistersharpe

Yes, it's currently switched off but if it does go back on in the future, I can't switch it off again.

Please can you only reboot and don't do a factory reset (as this will switch it back on again)

mistersharpe — Mon, 24 Jun 2024 20:55:26 GMT

Hi Debbie,

I rebooted the router. The channel did change from 36 to 100. But I just checked again tonight at the signal seemed off, and it's back on 36 again.

Is there honestly nothing we can do to make these settings stick?

Thanks,
Carl.

Hi @mistersharpe

WIFI optimisation is still showing as switched off so It's not changing the wireless channels.

When did we last send you a new router for testing?

mistersharpe — Tue, 25 Jun 2024 08:47:50 GMT

Hi Debbie,

I can't remember but you did a few years back. Are TT still using the same Sagemcom routers?

Carl.

Re: 5G WiFi unreliability last few weeks Feb-Mar '23

Debbie-TalkTalk — Tue, 25 Jun 2024 08:52:58 GMT

Hi Carl

Yes this would be a Sagemcom WIFI hub. This would also have WIFI optimisation switched on.

mistersharpe — Tue, 25 Jun 2024 10:08:12 GMT

Debbie,

Right, so what benefit is having another router for testing if it's going to 'optimise' my channel? 🤔

Carl.
