ndiswrapper and WPA

Posted by: Julien @ 10:25 pm

I had been using ndiswrapper with a Netgear WG511 PCMCIA card[1] without any problems for a while, then have begun to get kernel crashes, which were more and more frequent.

I have thus backported to Etch the 1.47 version available in Sid, which *does* fix my kernel crashes.

However, this newer version has brought new problems: with a “high” network load, the module just crashes silently, and has to be reloaded so that the network connection can be enabled again.

I have packaged ndiswrapper 1.48 as the release notes let me think my issues were fixed (”Disassocation with wpa_supplicant is fixed”), but the problem is still there with this latest release!

I have finally managed to get things work correctly thanks to this post: I use Debian linux-image, ie. without preemption enabled, and I can now confirm the still-to-be-released 1.49 version fixes this issue.

I have uploaded 1.49-rc3 packages to my unofficial repository just in case someone has the same issue.

If it is a fullmac prism54, you might want to try that patch:

Not sure if it even made it to the kernel.

Thanks, I wasn’t aware of this patch.

I will try it on a test machine, but if ndiswrapper 1.49 works, I will stick with it until I get a new card.

Cheers,
Julien
