Default settings. This is just an speed test. With torrents speed is up to 12MB/s.

Thanks a lot for your speed test,InoX.
Did you ever see the log like this?

Try with something with windows. Not apple products.
Distance - > indoors
Power -> Default

The Power will affect this?looks like impossible.

looks like you did some changes to the wireless interface and that triggers the wireless client to disconnect.
Wireless client didn't get the message about the disconnection and still tries to communicate with the AP till it realizes it needs to reconnect.

I didn't,if i did,there will be some log about it,right?

This log entry is showing that is it disconnecting all the wireless clients, as maybe you enabled some monitoring tool, for example, scan?

Why you don't just reset to default and see if not something wrong with your configuration...?!
Setting manual tx power can affect wireless clients btw.

Well,sounds reasonable,thanks.

Well,I've reference the offical manual,looks like HW.Reties & Disconnect Timeout will affect the "data from unknown device" error.
