Description Richard Riley Gress 2012-08-18 19:42:13 UTC
[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.

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:

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.

Your regulatory rules are all messed up. Wireless cannot use any 20 MHz channels, and I bet that you need them.

Install the crda package for your distro and create the file /etc/modprobe.d/50-chg80211.conf with a single line that says

options cfg80211 ieee80211_regdom=XX

where XX is your country code (I use US).

Thank you for providing a hypothesis, but after following the instructions the problem exists.

Comment 14 Larry Finger 2012-11-08 22:05:07 UTC
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.
Comment 15 Richard Riley Gress 2012-11-09 01:09:11 UTC
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,

Comment 16 Larry Finger 2012-11-09 16:59:41 UTC
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.
Comment 17 Richard Riley Gress 2012-11-09 21:47:52 UTC
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.
Comment 18 Larry Finger 2012-11-09 23:45:42 UTC
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.

Larry Finger, thank you for reviewing this report. As I have been helping Richard Riley Gress through the downstream triage process, I just wanted to briefly interject about his comment:
(In reply to comment #17)

This is not an official Ubuntu kernel. It is a unmodified mainline (upstream) kernel. For more on this please see https://wiki.ubuntu.com/Kernel/MainlineBuilds .

Thank you for your understanding.

Thank you for pointing this out. My apologies for using the incorrect terminology here.

.config file attached.
Comment 25 Larry Finger 2012-11-13 20:51:14 UTC
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.
Comment 26 Zhuravlev Uriy 2012-12-01 12:26:35 UTC
Hello. 
I have the same problem. I have:
  20f4: 648b TRENDnet TEW-648UBM 802.11n 150Mbps Micro Wireless N Adapter [Realtek RTL8188CUS]

All networks visible, the association with the point of going on but no packets received.
Here is the log with the modprobe rtl8192cu debug = 4 and perform the following commands:
ifconfig wlan0 up
iwconfig wlan0 essid nya # (open network)
dhclient wlan0

My uname: Linux sagita 3.6.2-gentoo # 2 SMP PREEMPT Sun Nov 11 01:51:17 MSK 2012 x86_64 AMD FX (tm) -8120 Eight-Core Processor AuthenticAMD GNU / Linux
Log link: http://pastebin.com/M2iZimGw

PS CONFIG_CFG80211_REG_DEBUG is not set :)

HALLELUAH!! 'Tis resolved.
Comment 29 Richard Riley Gress 2013-01-11 04:32:56 UTC
Never mind; bug is not actually fixed. rtlwifi and accompanying modules were loaded, and web data could be downloaded, at least on the first reboot after installing 3.8-rc3. On the second, third, and fourth reboots, the same behavior as before was present.
