Indeed, I think the driver itself needs to be investigated: there's at least one indication of issues with reloading the firmware:
Sep 16 23:03:42 yyy-W240HU-W250HUQ kernel: [16829.885737] rtl8192c_common:rtl92c_firmware_selfreset(): 8051 reset fail. Sep 16 23:03:46 yyy-W240HU-W250HUQ kernel: [16834.773964] rtl8192c_common: Loading firmware file rtlwifi/rtl8192cfw.bin Sep 16 23:03:53 yyy-W240HU-W250HUQ kernel: [16840.968894] rtl8192c_common: Loading firmware file rtlwifi/rtl8192cfw.bin We don't have logs for a suspend/resume cycle. Could you run through the process of suspending your computer, resuming, and attaching /var/log/syslog? It would be important to see clearly if there are other relevant messages from the kernel during the resume, either for a firmware reset or when the card goes into ready state. Adding a task for 'linux' since it's pretty likely to be a kernel issue. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: network-manager (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1051816 Title: No Wi-Fi at startup; disabling and enabling wireless fixes it -- Realtek RTL8188CE rtl8192ce Status in “linux” package in Ubuntu: New Status in “network-manager” package in Ubuntu: Incomplete Bug description: Ubuntu12.04.1 1) Shutdown the PC 2) reboot the PC, start the Ubuntu session Expected result: Wi-Fi networks are detected in the Network applet Observed result: no networks appear in the Network applet.
