[Luke <852190@xxxxxxxxxxxxxxxxxx>]

I have the same hardware as described in the first comment, Edimax EW-
7811Un.

With  3.11.0-12 kernel in Saucy, I cannot connect to my WRT54G access
point.

If I use the drivers from: https://github.com/pvaret/rtl8192cu-fixes
my Wireless card works perfectly

With  Linux kernel 3.13 in a Trusty Tahr beta install, I can sometimes
connect to my network, but the network frequently disappears. The only
way to connect is to remove the USB device or reboot the computer.

kernel.org Bug 45241 was closed, but the kernel 3.13's driver does not
work as well as pvaret's fixes with 3.11. Does Ubuntu's 3.13 contain
Larry Finger's patch?  If so, more work still needs to be done to fix
the driver in the kernel. Should I create a new bug report or reopen
45241?

Please let me know if there is anything else I can provide to be of
assistance.
