Atheros AR9227 - Wireless randomly looses connection

Hello everybody,

Sometimes my wireless connection are going south, but reconnecting again a secund later. It happens around 3 times in an hour. It's minor nuisance, as it reconnect again fast.

My System:

-best regards

I have now installed the non-free version of the driver. Lets see how that will go. :slight_smile:

Using the non-free driver seems to have solved the problem.

Could you please elaborate exactly which driver are you referring to. I thought this adapter simply uses the Ath9k kernel module. I was unaware there is another driver version.

Sure, but I'm bit confused if it's a free or non-free. The set up in the hardware configuration is a bit confusing. I assumed that the right boxes is non-free and the left boxes is free.


I believe that was the driver for your Ethernet that you installed. That would likely have been the r8168 proprietary Realtek LAN driver you installed.

But ... I don't loose connecting anymore ... weird.

Yes, very strange. That is not something that would be expected to occur.
