Description Dano 2013-10-11 16:39:11 EDT
Description of problem:
During an scp transfer, moving anything on the desktop brings down the wifi thus stalling the transfer.

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

How reproducible: Always

Steps to Reproduce:
1. On a wifi connected system, on gnome desktop, open a terminal window.
2. Start an scp copy or sftp from another system
3. When the tranfer speed indicated stabilises (~2.5MB/s on my system), open another terminal window.

Actual results:
The transfer speed will drop until it stalls.
NetworkManager will eventually (usually more than a minute later) report the lost connection.

Expected results:
sftp/scp transfer should continue unabated while using other desktop features.

Additional info:
1. Disabled NetworkManager, started wifi wpa_supplicant manual. Sill fails.
2. Loaded KDE. Doesn't fail on KDE.
3. Reloaded laptop with fresh ditribution, latest updates. Still fails

Since yesterday's update, wifi fails as soon as an SCP transfer is started.

At run level 2, the wifi stays up and the SCP proceed at ~2.5MB/s until completion.

Since yesterday's update to kernel 3.11.6-201.fc19.x86_64, this problem hasn't reoccured.
