Can not find wifi SSID on WAVLINK WN570HA1

Installing and Using OpenWrt Network and Wireless Configuration
1

I recently installed OpenWrt on my WAVLINK WN750HA1. I am really enjoying it, however I can not find the default SSIDs for both radios either on my phone or my PC but I can enable the radios and do successful SSID scans using each of the them. I have radio1 disabled for now but the problem also affects it.

OpenWrt 21.02.0 r16279-5cc0535800

Any ideas to get it working?

Hey! No one?!

A radio or a phy is the whole radio, which may be running multiple SSIDs. An interface (wlanX) or a dev is an individual AP (attached to a radio).

Use iw dev to see if your AP device has been created.

That looks normal, they should be on the air.

Do you see a line with "AP-ENABLED" (for wlan0 and wlan1) in the log?

Yes I can find them but the AP are yet not visible.

Everything there looks normal like the APs are usable. Do you see anything with those MACs on a wifi analyzer app?

I did check now. No, I can not find any of them.

Edit:
Upon further inspection, I found that it actually broadcasts the APs as long as I am having my phone beside the antennas. So, I teared it down and found one little rogue smd inductor that has failed partially open circuit, I bridged it and the signal was up.

At last it was a hardware issue.

Thanks.
