New eero router drops 5ghz devices to 2.4ghz after initial set-up

[Iandswift]

Hi,

3 days ago I upgraded from Fibre 65 to Fibre 150 and received the new eero router.  I set everything up and all was fine, my TV's and PC all connected on 5ghz and I was getting the promised speed of 150mbps but the following day I ran another speed test and it had dropped significantly to 35mbps.  I checked my connection and found my TVs and PC where now on the 2.4ghz band.  I messaged support and eventually they told me to delete my eero network via the eero app which I did.  I ran the set-up again and my TV's and PC all connected to the 5ghz band, brillant I thought, solved.  They all stayed connected for the rest of the day so the following day I checked again and frustratingly they again were back on 2.4ghz.  I have found in this community others experiencing the same issue but can't see it there's a solution.  I did read one thread where the 5ghz band channel range was too high for some devices.  Using WiFi Analyser I can see my 5ghz band is up around channel 155, could this be the issue?

At the moment my main house PC has gone from 75mbps of Fibre 65 service to 35mbps on Fibre 150 so it feels like a downgrade.  Any solutions out there please?

Many thanks,

Ian.

Many thanks Keith. Using WiFi analyser app I've now shown that in initial set-up my eero broadcasts 5ghz on channel 43 but overnight changes to channel 155.  I have run this test a few times now and it always repeats the same pattern.  When broadcasting on channel 43 all my devices can connect to 5ghz but with the change to 155 overnight most of them drop off.  Good news there is a potential fix.

Yes, this is most likely the reason, most WiFi devices do not support such a high channel & they have no option but to use the 2.4GHz band. I have seen a number of Eeros stuck on 155, which there is a fix for. I have asked one of TalkTalk's support to pick your thread up and apply it for you.
