RT AX3000 wifi signals drops suddenly

[zubair845]

Last night my router (RT AX3000) suddenly disconnected. I restarted the router but the signal was not showing. I did hard reset and update the firmware from merlin to asus latest firmware but the signal did not show. I update again to merlin but the signal did not show. My router has 2.4 and 5G lights is still ON. Only i see wifi signals working at a distance of 1 ft .i set different channels but still signal is not showing more than 1ft distance.
when i connect with LAN wire internet is working.

Please help me

Try the suggested steps in the link below. Be patient after every reboot (15 minutes minimum). If the issue cannot be resolved, time for a new router.
