I would be more than happy to roll my own vanilla kernel to get this resolved. I did find a related post relevant to the RTL8192CU driver and a major bug discovered but no further information was posted in regards to the kernel fix. You must either reboot, rmmod-modprobe, or try and wave the magical dead chicken over the workstation. Other symptoms observed: Hotplugging the device to reset it sometimes results in Kernel panic and system reboots, restarting the network stack using 'service network restart' does not allow for the usb wireless device to resume normal operations. Workaround: Remove RTL8192CU using rmmod, using modprobe rtl8192cu to insert, repeat when data connection drops. No errors reported in dmesg, /var/log/message, /var/log/warn. Symptom: After passing a undisclosed amount of data, the wireless connection abruptly stops. What works: Association with AP, authentication using 802.1x, passing dataĬonfigured using: YaST (not using network manager, I need wireless to work from the console) Relevant package output from rpm -qa | egrep "(wireless|iw|kernel-firmware)" command:wireless-tools-30.pre9-28.2.1.x86_64 IdProduct 0x8176 RTL8188CUS 802.11n WLAN AdapterīInterfaceClass 255 Vendor Specific ClassīInterfaceSubClass 255 Vendor Specific SubclassīInterfaceProtocol 255 Vendor Specific Protocolĭevice Qualifier (for other device speed): IdVendor 0x0bda Realtek Semiconductor Corp.
