Red Hat Bugzilla – Bug 244529
bcm43xx wireless not functional
Last modified: 2008-06-16 21:37:24 EDT
Description of problem: I have found several other bcm43xx bugs on the list, but this does not seem to fit those descriptions. I have used both ndiswrapper and bcm43xx-fwcutter and still cannot get this to work fully. I am using a Dell B130 with an internal BCM4318 wireless card. I am using the bcmwl5.sys driver that actually is the driver that works on my windows side so I know the driver is good and it up to date. I install the firmware using the fwcutter and update the kernel mods and all seem fine and dandy. The problem comes when I bring the wireless up. I keep getting this : Error for wireless request "Set Bit Rate" (8B20) : SET failed on device eth1 ; Operation not supported. I also get the messages which I have attached when I use 'dmesg'. I also see the following error repeating on my access point server when I bring the wireless device on my laptop up: Wifi0: Stuck beacon; resetting (bmiss count 4) I have tried to change the channels around with the same result. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. See above 2. 3. Actual results: See above Expected results: Fully functional wireless Additional info:

This bug is a duplicate of bugs 242338, 242585, 243097, 243487, 243585, and 245084. It' obviously a problem for many users. The fix posted on fedora-list by John W. Linville here: https://www.redhat.com/archives/fedora-list/2007-June/msg01009.html doesn't work (at least for me, and, I suspect, for many others). Please pay attention to this bug. I think it's a NetworkManager problem.
Some useful information: [root@localhost ~]# iwconfig lo no wireless extensions. eth0 no wireless extensions. wmaster0 no wireless extensions. wlan0 IEEE 802.11g ESSID:"" Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated Tx-Power=27 dBm Retry min limit:7 RTS thr:off Fragment thr=2346 B Encryption key:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 [root@localhost ~]# lsmod | grep b43 b43 129637 0 rfkill 9297 1 b43 mac80211 112461 1 b43 input_polldev 7241 1 b43 ssb 29893 1 b43 [root@localhost ~]# ifup wlan0 SIOCSIFFLAGS: Operation not supported Error for wireless request "Set Mode" (8B06) : SET failed on device wlan0 ; Invalid argument.

When checking this file it came to my attention that the comment (#) is the same as the eth0? Although I dont think this is the issue, it just came to my attention.
By the way: the first error SIOCSIFFLAGS comes from the os trying to bring the interface up. See file: /etc/sysconfig/network-scripts/ifup-wireless: /sbin/ip link set dev ${DEVICE} up ("ifup-wireless" line 34 of 102 --33%-- col 1 )
Ok, I found a solution for my problem. http://www.crashcourse.ca/wiki/index.php/Broadcom_wireless_on_Fedora Also blacklist the ssb module in /etc/modprobe.d/blacklist [root@localhost ~]# cat /etc/modprobe.d/blacklist | grep "blacklist ssb" blacklist ssb [root@localhost ~]# The short solution is rebooting the system or else try to unload the ssb module.
To get the module loaded during startup put the following line in the /etc/modprobe.conf: alias wlan0 b43 The website I mentioned above says there should be something like: alias wlan0 bcm43xx_mac80211 in the modprobe file. For newer kernels (tested on fedora 7) this is not working. Load b43 instead and it will work!
This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists. Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs: http://docs.fedoraproject.org/release-notes/ The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 7 changed to end-of-life (EOL) status on June 13, 2008. Fedora 7 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
