Asus RT-N66U WIFI Suddenly become Very Slow

[audiocool]

Firmware: Merlin v3.0.0.4.376.45

Anyone using above Asus router encounter similar problem?
Tried this in my iphone and XiaoMi Mi-Box and the connection suddenly become very slow. If I'm using cable the connection is no issue.
The only thing I did was reboot the router.

Any setting will solve this? Kindly share your wireless setting screenshot.

Thanks.

Try the .43 fork. I had the same issue and it went away when changing to the fork (stickies at top).

Will the tx transmit power give any different in term of interference with neighbors' AP ?

At the moment, I choose channel 6 which have least AP overlapping with neighbours' AP.
