Hi,
My F20 PC currently has two kernels installed:
kernel-3.13.6-200.fc20.x86_64 and kernel-3.13.7-200.fc20.x86_64.
With the latest kernel my wifi connection constantly breaks, while the NetworkManager
still indicates a connected wifi; this happens with two different USB wifi gadgets.
While pinging I suddenly get:
ping: sendmsg: No buffer space available.
This does not occur when I boot with kernel kernel-3.13.6-200.fc20.x86_64; wifi is then
stable.
I'm afraid some bad wifi or network stuff came with the new kernel update!
(I don't know whether the cable connections are also affected; I haven't checked
that).
One of the wifi's is: ID 0846:9041 NetGear, Inc. WNA1000M 802.11bgn [Realtek
RTL8188CUS]

R.L.

Try to switch to a lower 802.11 band,
or roll the dice with kernel-3.14.0-0.rc8.git1.2.fc21.x86_64.rpm,
