why do you need to re-do all the WIFI devices? simply change the WIFI SSIDs on the hub to whatever your old one was called (and set the password to whatever it was). your devices will connect as if nothing happened.
The HUB4 looks and feels like a cheaply made plastic toy and I just found out its a Wave 1 device so no 160mhz (20/40/80 same as HUB3),
My previous Intel WIFI 5 AC NIC was 160mhz, current one is WIFI6 AX 160mhz.
Do not see any Smart WIFI settings though I have issues with that on smart devices so end up disabling it or having to fix it all the time.
Now I cannot sign in a second time (it did not refresh page after 2nd lot of changes, it did the first changes I made) claims password is wrong, this was a bug on the HUB3 as well (multiple threads on topic)
It is asking me to choose my language again, I am not doing a pinhole reset each time so will try reboot.
