phatsteve Posted June 18, 2007 Report Share Posted June 18, 2007 I've just switched to Mandriva from a number of different distros, I'm using Spring 2007-1. I have a Buffalo Airstation WiFi card that works fine with the broadcom driver in ndiswrapper, the problem is I have to set it up every time I re-start the laptop, this is getting tedious in the extreme! My /etc/sysconfig/network-scripts/ifcfg-wlan0 contains this:- DEVICE=wlan0 BOOTPROTO=dhcp ONBOOT=yes METRIC=35 MII_NOT_SUPPORTED=no USERCTL=yes RESOLV_MODS=no WIRELESS_MODE=Managed WIRELESS_ESSID=#### WIRELESS_ENC_KEY="open s:########" WIRELESS_WPA_DRIVER=wext IPV6INIT=no IPV6TO4INIT=no DHCP_CLIENT=dhclient NEEDHOSTNAME=yes PEERDNS=yes PEERYP=yes PEERNTPD=no (sensitive parts hashed out) I've read another post recommending locking xorg.conf file, but this seems a bit drastic. Can anybody please help? Thankyou Quote Link to comment Share on other sites More sharing options...
pmpatrick Posted June 18, 2007 Report Share Posted June 18, 2007 Is your ndiswrapper module loading on reboot? Check the output of: $ lsmod If ndiswraper is there, try starting from the command line and see what you get. As root run: # ifup wlan0 Unless your /etc/sysconfig/network-scripts/ifcfg-wlan0 file is disappearing on reboot, it should bring up wlan0. If your ifcfg-wlan0 file is surviving a reboot and you can bring up the network with ifup wlan0, there is probably some timing problem. Post back your results.

pmpatrick Posted June 19, 2007 Report Share Posted June 19, 2007 (edited) It's a conflict issue with the open source wireless driver "bcm43xx". Once this thing loads, it prevents ndiswrapper from creating the wlan0 interface. I had the identical problem on my laptop. You can see the bcm43xx driver listed in your lsmod output so it's loading at boot. The problem is bcm43xx loads by default and is set by mandriva and other distros as the default driver for all broadcom chipset wireless cards. Unfortunately, bcm43xx is very buggy in my experience and doesn't work on many boadcom based wireless cards, mine included. Ndiswrapper works much better in my experience. So much for the diagnosis; now for the cure. You have to stop bcm43xx from loading at boot. Then when ndiswraper loads, it usually creates the wlan0 interface(sometimes it's designated as "ethx" depending on which version of ndiswrapper and udev rules) and your network will come up without having to recreate everything every time you boot. This is called blacklisting a driver and different distros have different ways of blacklisting. In mandriva, you have to edit /etc/modprobe.conf and you need to be root to do that. Open a console, and run: $ kdesu kwrite /etc/modprobe.conf Enter your root password when prompted and kwrite will come up with root privileges displaying modprobe.conf. Add this line to modeprobe.conf: blacklist bcm43xx Save the changes, reboot and see if the bcm43xx driver is not loaded by running: $ lsmod | grep bcm If successful, run as root: # iwconfig that will list all network interfaces and tell you which one(s) have wireless extensions. It'll probably show wlan0 but on my laptop the wireless interface on mdv2007.1 is listed as eth1 when using ndiswrapper with broadcom . I'm curious to see what yours shows. At any rate, once you know the wireless interface name you can reconfigure it if necessary in mcc and it should stick. It may work fine without doing anything further since you already have a ifcfg-wlan0 config file but you may have to reconfigure if the wireless interface has changed names.

phatsteve Posted June 19, 2007 Author Report Share Posted June 19, 2007 Absolutely spot on! I amazed at how much you guys know about the workings of Linux! Thankyou very much, this completely solved the problem, my network was up immediately on re-boot.It's shown as eth3 now, not wlan0 but who cares? it works! Thankyou again.
