router tplink ax1500 - wifi 2.4ghz stopped suddenly working - now i cannot configured it
I have configured 2 wifi'es 2.4 and 5ghz for a long time. Yesterday 2.4ghz suddenlly disappeard. I was trying to reconfigure it however with no luck, when:
1. i run quick setup (with configuration for 2.4 and 5ghz it get stuck on 4 step "Connection Test". When i exit that setup i see only 5ghz available.
2. when i exit quick setup i try to do manual setup for 2.4 and 5 when i want to enable 2.4 it throws on the bottom with a message operation failed.

Additionally i have noticed that green LED is not visiable on the router for 2.4Ghz indicator (but this may be because it is off thats why).
