Is wired WAN connected anywhere?
Set country code in both wifi bands, and both access points with same name.
Yes wired wan is connected to my primary routers lan port
And as for country code it basically disables the wireless
For your information i can connect to my router the problem is i can’t access internet with wireless mode ,
Hard to guess you want wwan or wan to work, just reset the device or at least remove extra connections.
You have to wait for 5GHz to settle with radar detection. Like few minutes.
I have a primary router from which i want to give a lan to wan connection to my openwrt router ,, here is a crappy drawing
"Dumb AP" is better fit in your scenario.
You have 2 WAN connections, hard to guess which is active at any one time.
Regarding your setup there are a lot of things which need to be corrected.
The best advice, as already given, is to reset to default!
Setup as a Bridged (aka Dumb) AP over ethernet:
