Slackware 12 Wireless problems


Hello all!

I've just recently performed a complete and fresh installation of slackware 12. Up until recently, I was using slackware 11. The slackware installation was running on both a laptop and desktop PC, both are just plain old normal boring x86 32-bit systems. The wireless device I am using is a USB Netgear MA111. I connect to the internet via a server, which in turn is connected to a wireless router.

Under slackware 11, I could use the following script successfully to connect to the internet;

Code:
#!/bin/bash

modprobe prism2_usb prism2_doreset=1

wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
wlanctl-ng wlan0 lnxreq_hostwep decrypt=true encrypt=true
wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKeyID=0
wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11ExcludeUnencrypted=true
wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11PrivacyInvoked=true
wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKey0="XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX"
wlanctl-ng wlan0 lnxreq_autojoin "ssid=home" authtype="opensystem"

ifconfig wlan0 192.168.0.162 up
route add default gw 192.168.0.10
Under slackware 11, this works fine. Under slackware 12, it dosen't seem to work. If I try to ping - say - google.com I get absolutely nothing in return; under slackware 11 it would work fine. I know the internet is working as I am using another PC with slackware 11 on it, and the internet's working just fine. And with another netgear MA111 too (swapping them over didn't work at all).

Here is some more info;

If I were to do all of this under slackware 11, I'd have no problems; I could type "ping google.com" and get a response. I get no response whatsoever using slackware 12.

Sometimes if I turned everything off - the router & the server, left it for a while and switched it back on I could get it to work under SW12. But it seemed to be extremely hit-and-miss. Using another PC at the same time with a Netgear MA111 and running SW11 had no problems at all.

Even more bizarre though is that sometimes - once in a blue moon - it will connect and I can ping (say) google.com . But if I removed the MA111 device, waited a moment and plugged it back in chances are it would fail again. It all seems to be *extremely* flaky.

Can anyone think what's going on -- is there some big change 'tween Slackware 11 & 12 ?

The only change I know of that might affect it is the kernel. Which kernel are you using? I keep fairly up-to-date with the kernels and after around 2.6.19 I had problems with the wlan-ng driver. Eventually it wouldn't even build. Are you using a pre-compiled package or source for the driver? If it's pre-compiled did you make sure your kernel matches the one it was built for?

From your post it looks like the driver is complaining about IPv6. If you can, try to rebuild your kernel without IPv6. You can also check the output of the lsmod command. If ipv6 is listed you can blacklist the module so it doesn't load.

On a sidenote, I've been using ndiswrapper for this device and it works well.

Thanks, I'll give it a go . I'm using all the stuff btw that is on the SW12 DVD. I forget the exact kernel number though(!). And yeah it was a precompiled one.
