Hello,

Device: RT-N12+
Issue: WLAN is not working properly. When enabled the signal status shows 0db noise 0db. Wireless devices would properly show the SSID however unable to join. Even with No encryption. The system log would even show that radio0 is up.
Steps done:

  • Reboot Router
  • Re-flash firmware
  • Manually set WiFi config: Band 20mhz or 40mhz.
  • Toggled between N and Legacy.
  • Manually set WiFi channels.
  • Tried different encryption.

Additional information:

  • I am well aware that this router support is still WIP as stated: https://lede-project.org/toh/hwdata/asus/asus_rt-n12 Basically just putting out this bug report since so far everything seemed fine except for wireless broadcast.
  • Used latest snapshot build from downloads page dated: Thu Jan 25 12:07:37 2018

Confirmed on my Mi Router 3G (MT7621A), wifi dead for me as well after 99eb128
SSID are showing, smartphones are even connecting but shows "!" or simply unable to open any web page :(
