  Hi, My AX1800 router Network setup uses ‘X1’ VLAN and the other two on ‘LAN’ setting.
  When I tried the following, it can cause the router to go into a crash-reboot loop state when I try any of the below:
  a) reassign one of the port from ‘LAN’ to ‘X2’
  b) Setup a new WiFi to GUEST network.
  I did not modify the source/destination VLAN table.
  I’m not sure why this is happening. To stop the loop state, I need to use a paperclip to press the hard reset button to get the router back to factory settings.

  Any feedback or questions welcomed.

  Thanks

  @w9yu34ac8yd2 Can you send a copy of your backup file just before the change causing the crash-reboot loop to [email protected]?
