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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/852190 Title: 7392:7811 Edimax EW-7811Un USB dongle won't connect to networks (rtl8192cu module) Status in The Linux Kernel: Incomplete Status in “linux” package in Ubuntu: Confirmed Bug description: The networks around are visible, but when trying to connect, the NM repeatedly asks for the password.
