I seem to have got myself into a complete mess, there's a couple of similar threads here, but none help me.
I had everything running fine, main WiFi and guest2 Wifi are split with different SSID's for 2.4G & 5G with IoT stuff on the guest network.
I have two piHoles running DNS, their network addresses are in the WAN DNS Setting's fields on the "WAN - Internet Connection" page
Then I thought I'd install YazFi so I could tell which IoT device was making DNS requests. I installed it, realized the clients wouldn't appear in the network map page anymore, decided I wouldn't bother and uninstalled it.
I have never been able to get things working again. The guest network seems to be OK but I get strange results if I connect to 2.4G main network and 5G main network.
It seems that sometime (almost at random), DNS queries resolve to odd addresses, e.g. "bbc.co.uk" should resolve to "151.101.128.81", but sometimes gets an address like "198.18.1.73". It's inconsistant and random. I get different results between 2.4G & 5G. The problems only seem to affect my two Windows 10 P/C's, Android phones seem unaffected.
I have tried a factory reset from UI on the router, including formatting JFFS and rebuilding the router by hand (not from saved config)
I have also rolled back the P/C's using Macrium to a date when they were working, I've rebooted the PiHoles and flushed their caches.
Any ideas?
