As per larry Finger, this should be assigned to him https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1030858/comments/45 . However, when I attempt to do so: >"You tried to change the Assignee field from >drivers_network-wireless@kernel-bugs.osdl.org to Larry.Finger@lwfinger.net , >but only the assignee of the bug, or a user with the required permissions may >change that field." That's the same error I get. Please post the appropriate section from the dmesg output where it is trying to connect. In addition, if you use NetworkManager, please post the part of the of the NetworkManager log for a connection try.

Thank you for providing a hypothesis, but after following the instructions the problem exists. Does cfg80211 still complain? (In reply to comment #11) > Does cfg80211 still complain? It does: http://paste.ubuntu.com/1343734 Created attachment 86011 [details] specific dmesg output after following instructions in comment #9 It looks to me as if cfg80211 or crda is messed up. You still get those messages saying that 20 MHz channels are forbidden. Can you implement compat-wireless? That will provide a new version of cfg80211. I got compat-wireless, version 3.6.6-1-snp from http://linuxwireless.org/en/users/Download/stable/#Recommended and compiled the thing. Ubuntu system. Same problem, it looks like, however... this is what happens when I start up with it plugged in, http://paste.ubuntu.com/1343884 and this is what happens when I plug it in while started: http://paste.ubuntu.com/1343891 Did you build this kernel yourself, or is it one supplied by Ubuntu? In either case, what is the state of CFG80211_INTERNAL_REGDB in the configuration? On my system, it is not set. This is an official Ubuntu kernel, from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.3-quantal/ , I am going to test 3.7.0-rc4 as soon as I can. (dern graphics drivers...) 'echo $CFG80211_INTERNAL_REGDB' returns nothing. That command would not return anything. The kernel configuration options are not in the environment. Try zcat /proc/config.gz | grep CFG80111_INTERNAL_REGDB I don't know how Ubuntu configures their kernels, and the command might not work.

.config for 3.7-rc5 kernel
.config file attached. The inability to set 20 MHz channels is fixed by changing the value of the configuration variable CONFIG_CFG80211_REG_DEBUG from Y to "not set". The failure when that variable is set is certainly a bug, but it is not in rtl8192cu, but likely in cfg80211. It would have shown up for any wireless driver that uses mac80211. I will pursue that issue and submit the necessary patch. Hello. I have the same problem.

Patch to fix reassociation problems
The patch fixes a problem that prevented the driver from reconnecting after disconnecting.
A patch referencing this bug report has been merged in Linux v3.9-rc4: commit 9437a248e7cac427c898bdb11bd1ac6844a1ead4 Author: Larry Finger <Larry.Finger@lwfinger.net> Date: Wed Mar 13 10:28:13 2013 -0500 rtlwifi: rtl8192cu: Fix problem that prevents reassociation |
[1] Summary of Problem. 0bda:8176 RTL8188CUS does not connect to wireless networks [2] Full description of the Problem. The RTL8188CUS USB wireless card will not connect to wireless networks. The connection is attempted over and over again, and the password prompt reappears each time if the network has one, but a connection is never established. There is a workaround for this bug: Drivers can be obtained from the Realtek website. But they are required in order for the hardware to function properly. Additional info: The AP (router model: Verizon VersaLink D90-327W15-06) is set up to accept 802.11b or 802.11g type connections based on the type of connection the wireless card is trying to establish. I have tested this on two different networks, one with no password protection, and one with WPA. [3] Keywords.
