Hello,
after changing the hostname in luci setting page, the ssid is gone from the radius list. rebooting router twice still no show. Please advise! thanks!!
now after resetting for 3 secs, the web gui shows the new ssid but the broadcast list still shows the old (original) ssid.
also, there is no 2.4GHz on the list even if activating it already.
both 5.0GHz and 2.4GHz show on the LED. It just no 2.4GHz on the ssid list.
it's on repeater mode.
under luci setting page, network-->wireless, it shows qualcomm, 5GHz, the old router name with original password. so confused...
Update:
now both 5.0 and 2.4 are on but the router ssid is gone again...
Please share more information about your device and setup. Maybe even some logs 
Now the router is gone from the broadcast again, same as the 2.4 and 5.0. nothing shows up right. LED shows time with !, tor booting 0% and both 2.4 and 5.0 show on the screen. what is going on with this device.......
I just reset the network twice still don't see anything. i can't log in the web gui to retrieve the log at all...
Can you share us more information about your device type, firmware version and your setup steps?
