Wifi droping on one of my two Actiontec MI424WR routers

Question

Hi, using the excellent guide here, I connected two Actiontec MI424WR routers: router A is Gen I (Rev) and connects to the ONT so I get 1 gbps, wifi turned off, home office wired plugged into LAN.

Router B is Gen F (Silver) and I only use that for wifi in part of my house, connected to Router A via LAN ethernet.

Whereas for the past many years, wifi has been fine on Router B, now the same devices drop after a couple of minutes. I'm able to connect quickly, but keeps on dropping.

Any ideas as to what could be causing it? Again, the same devices (iPhones) on Router B wifi has worked fine for years.

Thank you in advance!

Seems to be solved. I started at square one of that doc and made sure that there were absolutely no connections on either router except for the configuration PC. Must have been an IP conflict.
