I have RouterBoard 751U 2HnD and it have worked ~ for 2 years, but now WIFI stop working.
SID just disappeared and no one device can see it. There was no any configuration changes.
Where to start searching the reason?
Thanks.
Log in, shut down the router and cycle the power. Then log in check if wifi is not disabled. If so enable it. Otherwise start scan and check if it is able to scan.
Yes, it’s able to scan.
