Xiaomi 4a router (gigabit edition) Internet not working

[bill888]

I'm not sure if it is significant, but your 21.02.2 config differs from my 21.02.1 openwrt default. Specifically:

@Cool-Guy-101

config interface 'wan'
        option device 'wan'
        option proto 'dhcp'
        option type 'bridge'

config interface 'wan6'
        option device 'wan'
        option proto 'dhcpv6'
        option type 'bridge'

ie. 'bridge' is enabled ?

edit - I changed the ip to 192.168.2.1 and it seems to be working but when I type (192.168.1.1) the url changes to a openwrt link. is there any way to stop it ?

Do you witness same problem when using another device such as a phone?
