Red Hat Bugzilla – Bug 255681
Kernel 2.6.22-4-65 breaks ndiswrapper
Last modified: 2007-11-30 17:12:14 EST
Description of problem:
Kernel update 220.127.116.11-65 breaks ndiswrapper and keeps wlan0 from connecting to
wireless network. ndiswrapper -l reports alternate driver of b43 vice
bcm43xx_mac80211. Wireless card is not recognized. When b43 is added to the
blacklist, the card is recognized and the wireless network is recognized, but
regardless of how many attempts are made, it will not connect through
system-config-network, NetworkManager Applet, or Wireless Lan Assistant
When I revert to Kernel i686 18.104.22.168-41.fc7 with the corresponding ndiswrapper
and with the b43 removed from the blacklist, the network is recognized and the
lan connects as expected.
Version-Release number of selected component (if applicable):
kernel i686 22.214.171.124-65.fc7 updates
kmod-ndiswrapper i868 1.46-126.96.36.199.4_65.fc7 livna
1. Use yum to update f7 installation, which installs the two updates listed above.
3. Network card will not initialize
4. use ndiswrapper -l to list the driver (bcmwl5 : driver installed; device
(14E4:4320) present (alternate driver: b43)
5. Add b43 to /etc/modprobe.d/blacklist
7. card initializes
8. network attempts to connect unsuccessfully. NetworkManager applet shows
activity, but Netspeed applet shows no traffic being transferred
Revert to previous kernel (188.8.131.52-41.fc7)
Revert to previous blacklist configuration
Network will then connect normally
Steps to Reproduce:
1. see above
Network fails to connect
Network should connect and work.
There is a Fedora Forum thread which discusses this problem:
ndiswrapper is unsupportable...
Problem also appears in the X86_64 version.
