I tried the route of bypassing BT router by turning everything in that router off and using it as a wan port to my TP-link router so only link is lan to wan connection and wan out to internet. You can't turn off the Smart setup of smart hub because all it does it reboot router
wifi from tp-link using port forwarding works great and internet stays on, but that smart setup must be the random rebooting causing issue with skyQ
Smart setup no longer exists on the Smart Hub. It was permanently disabled by the last firmware update.
Do you mean Smart Wireless? If so, you can select channels manually but you need to save the changes.
Sorry if I sound like a tech but I have spent years setting up routers and internet and electrics as i am an electrician engineer 30+ years and was doing it before you even had a pc
If I had the info I would build a modem but but would need the coding from openreach to connect with BT. I can build a pc no problem,
most don't change the security login on routers
