Description Dave Cross 2014-01-02 10:34:24 UTC 
Description of problem:

Wifi has become a bit of a lottery. It's just not solid enough to rely on. Every so often it just stops working. The icon in the notification bar doesn't change, I just lose all connectivity. The only solution I've found is to turn the wireless off and back on again. But it can take five or six attempts for the wifi to reconnect. And when it does reconnect, half of the time it will drop again within minutes. The rest of the time I'll get a pretty solid connection that will work for a few hours before it drops and I have to go though the same cycle again.

This was starting to be a problem before I upgraded from Fedora 19. But Fedora 20 has made it far worse. Booting the laptop into Windows gives me a rock-solid connection. And my desktop (also connecting wirelessly and running Fedora 20) seems far more reliable. It's just the wifi driver in the laptop that's a problem.

Version-Release number of selected component (if applicable):


How reproducible:

Every time :-/

Steps to Reproduce:
1. Connect to wifi
2. Wait
3. Notice that wifi has dropped start again

Actual results:

Wifi connection drops frequently

Expected results:

A usable wifi connection.

Additional info:

Laptop is a Dell XPS 14z. Upgraded from Fedora 19 to Fedora 20 using fedup.

I'm aware that I'm not giving you enough information here, but I don't know what is useful. Please ask for any diagnostics you need.

Also, I have no idea at all which component causes this problem, but Bugzilla won't accept "Unknown", so I've guessed at "kernel". Please reassign to something more appropriate.

Let's start with "uname -a", "lspci -nvvv", "dmidecode" and var/log/messages attached to this BZ ;)

Kernel component is fine.

Thanks,
Michele
