The built in rtl8192cu driver has never worked for me. I only got the device 4-5 months ago and at first I couldn't even connect I believe that issue was related to LP#852190 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/852190/comments/170). I switched to the native driver with some patches i found online setup via dkms. That has worked well, but I figured I should report the issue with the rtl8192cu driver. I did test the mainline kernel last night (9/2) and the issue was still present. On Tue, Sep 3, 2013 at 1:28 PM, Joseph Salisbury
