The point is, I examine the state of your WiFi & help you set it up to be the best it can be. This not only covers WiFi interference but also signal strength. This will also give a good idea as to why the devices are band steered over to the 2.4GHz band.    

Hi I have a similar problem.  Husbands laptop is ok but my tablet will not scan and says not protected.  I also get a white blank screen (?virus!!!) If I uninstall on my tablet will it also uninstall from husband's laptop.   Susan

Hi Keith   Thankyou for getting in touch however I don't think it's to do with neighbours as all devices are are being knocked off 5ghz to 2.4 and getting stuck there even at 3am in morning. I'm now factory twice a day to get any device on 5ghz. I've followed all interference advice and dropping connection that talk talk give on here and still nothing. Earlier I connected via LAN my speed was 0.74mbps I'm on the 250 package I don't know what I'm paying for. It's worst than sky when on 80 fibre package

Hi @Billx    I don't want to dwell on this, as it is not your thread. However, a daisy chain network - that is not a term used in 802.11, one router is an extender from the other. As to your other question, this all depends on how you connect your 3rd party router & the way that you configure it. To use the same subnet as the Sagemcom, you would need to put the other router into bridge mode (it is then just an AP, no routing at all), give it an IP address on the 192.168.1.0 network and connect the Sagemcom to one of its LAN networks. You will also need to disable one of the DHCP servers. Clients connected to either router have full connectivity between them   Connecting the Sagemcom to the WAN port of the other router means that you should not enable bridge mode at all but that the 3rd party one must be on a different network (e.g. 192.168.2.0). This time clients connected to the 3rd party router can connect to the ones on the Sagemcom, but you may need port forwarding to configured for the Sagemcom clients to access servers on the 3rd party one.

I've done that and now on wits end I've tried everything and still all devices are being knocked off 5ghz onto 2.4 and can't change this till factory reset I'm now doing 2 reset a day. And my connection earlier using LAN was 0.74mbps like slower than slow

The Eero in bridge mode is the complete opposite of modem mode. If you enable that, then you will have no internet access. This is because bridge mode disabled all routing and you will never be able to route between your private IP network & the public one.

Nothing to do with my records, @dencole01, but with Arne's reply on your previous thread, which you then did not respond to.    And it's not "my" "so-called Auto-Compensation department."   I am a customer like yourself. Just drawing your attention to previous staff statements. 

Thanks Keith, I will look into setting up the VLANs again when I have a bit more time. I am all set up and working with double NAT again using the Sagemcom. The Eero arrived and I set it up in bridge mode but there isn't a way to turn off WiFi, so I went back to the Sagemcom. The eero in bridge mode would have avoided the double NAT so it's a shame wifi can't be turned off. Maybe they will provide an update in the future to enable that feature.    For anyone new who is looking for fftp and want to use their own router and APs, Talktalk with the eero probably isnt the right choice. I was just lucky I already had a talktalk sagemcom router that I could use as an alternative.    Thanks again to you and Chris for your support on this. 

@Debbie-TalkTalk wrote: Hi Peter   I completely understand. I can raise a complaint and ask a complaints manager to contact you by email to discuss this further? Yes please Debbie. I find it very irritating that this automatic Channel selection is enforced upon me. I will resolve this one way or another. If TT cannot disable this very annoying feature for me, and allow me to select my preferred WiFi 2.4 Channel,  I will have no choice but to abandon the TT router in favour of some alternative model. That is a real pity as in all other respects this router is serving me very well and I would prefer to stay with it if I can get this issue sorted. Cheers Peter.
