Author Topic: Wifi broadcom 4312 drops out  (Read 2152 times)
« on: July 06, 2008, 21:02:55 PM »

I have a broadcom 4312 wifi in my HP Compaq nx6325 and the b43 driver from the kernel detects it. I can set up the wlan0 without a problem, but after a random time, the flow stops.  The connection seems on but no traffic is generated anymore.
The only solution is to go to the network-applet, disconnect and reconnect the wifi. Then I am up and running until the next drop.

I do have the XP driver (bcmwl5.inf and .sys) and I would like to test it using ndiswrapper, because on the same laptop, PCLinuxOS using the bcmwl5 gives me exellent results.

I tried the following:

  • blacklisted the b43 in /etc/modprobe.d/blacklist-compat and rebooted
  • ndiswrapper -i bcmwl5.inf
  • ndiswrapper -l (shows me the driver is loaded)
  • depmod -a (no errors)
  • modprobe ndiswrapper
  • ndiswrapper -m (I expected something like adding "alias wlan0 ndiswrapper" to /etc/modprobe.d/ndiswrapper ... but I get a message that an alias is already set). When I look in /etc/modprobe.d/ndiswrapper I see a line 'alias wlan0 ndiswrapper'
  • iwconfig (doesn't show me a wlan0 device), neither does the network-applet

What did I do wrong ?

I had a similar problem with a different wlan device in Pardus 2007.2.
Later on the problem was diagnosed to be in the router, and had nothing to do with Pardus.
Here is the bug: http://bugs.pardus.org.tr/show_bug.cgi?id=6486
Maybe it will help to diagnose the problem or make a workaround.
And as my last advice: create a bugreport if needed.
