Q: Device not found! Wifi issues on El Capitan

Ever since upgrading to El Capitan my mac has trouble finding my routers.

The airport express, setup as a wireless range extender connected to my stereo, is suffering most. But my main router (airport extreme) is also having problems every once in a while.

 

It just suddenly says "device not found". When i go into airport utility it can't find both my routers. Sometimes it finds just one of them.

Turning wifi on and off solves it, for a while... My iPhone's airport utility and wifi-diagnostics says everything's OK.

 

I tried everything: resetting the entire network. deleting network settings, resetting PRAM/SMC, changing settings on the router. But the message just keeps coming back.

 

Eventually i reverted back to Yosemite and the issue is gone.

 

Is this a bug in El Capitan?

Anyone else having these issues?

Any thoughts on this matter are very much appreciated!

 

Thanks!

iMac (21.5-inch, Late 2012), OS X El Capitan (10.11)
