TP Link Archer VR2800 router Virgin Media Hub 3.0 Wifi setup

Put Hub 3.0 in modem mode on 192.168.0.1. Turn it off. You MUST TURN IT OFF NOW.

TP Link Archer VR2800 192.168.1.1 > "Operation mode" > "Wireless router mode" (was "DSL Modem/Router mode" by default).

Custom configs we had, not sure if mandatory:

Wait for TP link to fully reboot.

Connect port 4 of tp link (marked WAN/LAn) to port 1 of VM Hub (unmarked, but it is magic, has to be port 1).

Finally, AFTER everything else is setup, turn on the Hub and wait for a few minutes. It ONY WORKS if you turn it on after everything is setup.

Outcome:

hub light turns purple: www.reddit.com/r/VirginMedia/comments/c703t6/purple_light_on_the_box/
Archer WAN light turns on white. Not red. Red means error
you have Wifi. Notably, the 5G Wifi is way way faster and reaches the WAN limit of 256 Mbps.
Ethernet does not work anymore on either Hub nor Archer, Wifi only. But it doesn't matter because the 5G Wifi already reaches the speed limit.
