Hi klseet,

I follow all your intrusction and successfully patch the RT-N13U-B1 firmware to 2.0.2.5g but my problem does not solved. please help if you dont mind.

Previously i am using firmware 6.21.2.3 but i having problem of the whole router will hang which mean i can not ping the router either connect using WIFI or LAN cable. The router just reply Request Timed Out when i ping it.

After i patch the new firmware, the problem still exist. I was using about 1-2 hour, the router will disconnect from LAN. i restart it and everything is ok. Internet(Unifi) is very stable, my WAN ip seldom change but only dont know why the router will lost connection from LAN. i not even can ping it.

your help will be much appreciated. Thanks
