Very confusing :-( I see in modinfo, what makes me think it uses rtl8192cfw: firmware: rtlwifi/rtl8192cfwU_B.bin firmware: rtlwifi/rtl8192cfwU.bin firmware: rtlwifi/rtl8192cfw.bin
but: description: Realtek 8192C/8188C 802.11n PCI wireless With a clean install of Ubuntu 12.04, upgraded to kernel 3.2.0-54, wireless does not work: error in dmesg "Failed to request firmware!" There are a quite a lot of differences with your output, you are right that the problem lies at ubuntu packaging. While testing this, I noticed that rtl8192cfwU_B.bin and rtl8192cfwU.bin where missing and requested by the driver. Copying those in from the Realtek website makes the wifi work again :-). missing in the Ubuntu installation: rtl8188efw rtl8188eufw rtl8192cfwU_B rtl8192cfwU rtl8192cufw_A rtl8192cufw_B rtl8192cufw_TMSC different: rtl8192defw rtl8192sefw rtl8712u the same: rtl8192cfw rtl8192cufw rtl8723fw_B rtl8723fw Details of test machine: test@test-Intel-powered-classmate-PC:/lib/firmware$ md5sum rtlwifi/* 748944fbffd3b08b5b1929bb6c7fc537 rtlwifi/rtl8192cfw.bin 943e9b714a926e630b8152d7aad91d2e rtlwifi/rtl8192cufw.bin 7a3b61dbd72e0efb22f892ece8020994 rtlwifi/rtl8192defw.bin bccf9bf2276621770f101a60736b4004 rtlwifi/rtl8192sefw.bin 8e6396b5844a3e279ae8679555dec3f0 rtlwifi/rtl8712u.bin ce50dfe07dbb1bfe9e14bdb315a4b28a rtlwifi/rtl8723fw_B.bin 69ccaffbe94cc0ef1b89c25290e19b2e rtlwifi/rtl8723fw.bin test@test-Intel-powered-classmate-PC:/lib/firmware$ ls -l rtlwifi/ totaal 308 -rw-r--r-- 1 root root 13540 dec 11 2012 rtl8192cfw.bin -rw-r--r-- 1 root root 16014 dec 11 2012 rtl8192cufw.bin -rw-r--r-- 1 root root 20526 dec 11 2012 rtl8192defw.bin -rw-r--r-- 1 root root 88856 dec 11 2012 rtl8192sefw.bin -rw-r--r-- 1 root root 129304 dec 11 2012 rtl8712u.bin -rwxr-xr-x 1 root root 22996 jul 11 14:43 rtl8723fw_B.bin -rwxr-xr-x 1 root root 11662 jul 11 14:43 rtl8723fw.bin test@test-Intel-powered-classmate-PC:/lib/firmware$ modinfo rtl8192ce filename: /lib/modules/3.2.0-54-generic-pae/kernel/drivers/net/wireless/rtlwifi/rtl8192ce/rtl8192ce.ko firmware: rtlwifi/rtl8192cfwU_B.bin firmware: rtlwifi/rtl8192cfwU.bin firmware: rtlwifi/rtl8192cfw.bin description: Realtek 8192C/8188C 802.11n PCI wireless license: GPL author: Larry Finger <[email protected]> author: Realtek WlanFAE <[email protected]> author: lizhaoming <[email protected]> srcversion: DA52BF758B7683607AFCB85 alias: pci:v000010ECd00008176sv*sd*bc*sc*i* alias: pci:v000010ECd00008177sv*sd*bc*sc*i* alias: pci:v000010ECd00008178sv*sd*bc*sc*i* alias: pci:v000010ECd00008191sv*sd*bc*sc*i* depends: rtlwifi,rtl8192c-common,mac80211 intree: Y vermagic: 3.2.0-54-generic-pae SMP mod_unload modversions 686 parm: swenc:Set to 1 for software crypto (default 0) (bool) parm: ips:Set to 0 to not use link power save (default 1) (bool) parm: swlps:Set to 1 to use SW control power save (default 0) (bool) parm: fwlps:Set to 1 to use FW control power save (default 1) (bool) parm: debug:Set debug level (0-5) (default 0) (int) *-network UNCLAIMED description: Network controller product: RTL8188CE 802.11b/g/n WiFi Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:02:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list configuration: latency=0 resources: ioport:2000(size=256) memory:80100000-80103fff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/902557 Title: 10ec:8176 Wireless not working in 12.04 for rtl8192ce (RTL8188CE) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/902557/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
