Wifi Issues EDIMAX EW-7811UN

Sat Jun 01, 2013 7:45 am

Hello,

i use the EDIMAX EW-7811UN Wifi dongle. When i do downloads with high download rates (about 3MB/s) the Wifi stick just stops working. Then i have to pull an replug it to get it work again. Sometimes the connection loss comes after a couple of hours or within some minutes. May that be the power? I got a 5,4V 1000mA power supply.

If you can try using a different power supply because, although it says 1000 milliamps, it may not actually be providing that or may be faulty.

You could try the fiq_split branch to see if that fixes your problem, I'd be very interested if it does (there is a possibility that it might help out)

sudo BRANCH=fiq_split rpi-update

If you don't know about rpi-update then google it...

Thanks! I've had the same problem with the EDIMAX. Now the wireless works.

I'd try it in a PC before I started troubleshooting the Pi or its apps.
