4.5.4 has been pretty good for me. Haven’t ‘upgraded’ since the dramas with the firmware. Hoping the new commits in MT76 chipset on openwrt produce a 23.05 / 24.05 firmware soon.
adguard has been ok since i removed the client setting to block YT between certain times. AgH made changes to the timezone code to assist with the scheduling and I suspect that’s caused an issue.
Logs showing about login issue. So it is not WiFi issue.
About problem visit any website that is your Adguard Home filters.
If problem with WiFi that is your DHCP problem with router. Try handle dns to adguard home.
