[CentOS] CentOS 6, Broadcom, missing wlan0
This is a continuation of my previous thread: Broadcom Wifi Problem Following a post from James A. Peltier, who said: You can use the rpmforge version or compile it yourself. I've used this one with success using the details described earlier. http://www.broadcom.com/support/802.11/linux_sta.php I did however have to patch it with http://www.broadcom.com/docs/linux_sta/5_100_82_38.patch the driver built and installed fine. In fact, I'm using it on my laptop as we speak. On my CentOS 6, with BCM4311 802.11b/g. I installed: hybrid-portsrc_x86_32-v5_100_82_38.tar.gz With NetworkManager shut off, I see: #lsmod | grep b43\|ssb\|wl wl 2635904 0 lib802114858 1 wl and I try to start with: ifup wlan0 I put debug in the script, following into nested scripts, and see that it ultimately fails because: ip -o link fails to return wlan0 . I rechecked the MAC address, which is correct. Also ifconfig and iwconfig do not see wlan0 . Also, the wlan0 light on the box doesn't turn from red to green. If, however, I reenable b43, the light does turn green. Also, on this dual boot box, the WinXP partition runs WLAN0 with no problem. Thanks for your suggestions.

Instructions are very clear, and it worked fine for me a few months back for a new laptop (can't remember the brand or model) where I was installing C6 x86_64. http://elrepo.org/tiki/wl-kmod I followd the instructions at: http://elrepo.org/tiki/wl-kmod and I certainly saw some new stuff installed, and I am impressed with the approach to the copyright problem. I got as far as: # modprobe wl FATAL: Error inserting wl (/lib/modules/2.6.32-71.29.1.el6.i686/extra/wl/wl.ko): Unknown symbol in module, or unknown parameter (see dmesg) # dmesg wl: Unknown parameter `nohwcrypt' But I forgot the crypt library so I did: # modprobe -r b43 b43legacy ssb wl lib80211 # modprobe lib80211_crypt_tkip # modprobe wl FATAL: Error inserting wl (/lib/modules/2.6.32-71.29.1.el6.i686/extra/wl/wl.ko): Unknown symbol in module, or unknown parameter (see dmesg) #dmesg ... lib80211_crypt: unregistered algorithm 'NULL' lib80211: common routines for IEEE802.11 drivers lib80211_crypt: registered algorithm 'NULL' lib80211_crypt: registered algorithm 'TKIP' ... wl: Unknown parameter `nohwcrypt' I then googed around and did: insmod /lib/modules/2.6.32-71.29.1.el6.i686/extra/wl/wl.ko nohwcrypt=1 and it did -1: Unknown Symbol. Since this error is known to be related to the crypt libraries, I redid them. It didn't help, but just for grins I tried: insmod /lib/modules/2.6.32-71.29.1.el6.i686/extra/wl/wl.ko It retrurned no error. It seems that it got the nohwcrypt=1 once and doesn't want to see it again. I note that the hard drive partition is encrypted, in case this is relevant. BUT the problem posted in this OP of this thread still persists. Perhaps this installation is good, but wlan0 is still not seen. Here is my ifcfg-wlan0: DEVICE=wlan0 HWADDR=xx:xx:xx:xx:xx:xx NM_CONTROLLED=no ONBOOT=no TYPE=wireless BOOTPROTO=dhcp IPV4_FAILURE_FATAL=yes NAME=System wlan0 WPA=yes USERCTL=yes IPV6INIT=no PEERDNS=yes ESSID= CHANNEL=1 MODE=Auto RATE=Auto SECURITYMODE=restricted Thanks again for your suggestions, Mike. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I now get resulis from: ip link and the beginniongs of a connection. But I get: Error for wireless request Set Encode (8B2A) : SET failed on device wlan0 ; Invalid argument. Error for wireless request Set Encode (8B2A) : SET failed on device wlan0 ; Invalid argument. Yes, twice. Googing around I see that this is an old problem. I tried fiddling with the password. Sometimes the password is echoed in the error report, and sometimes not. I even tried a hex password. Nothing worked. More suggestions, or perhaps a better driver, would be much appreciated.
