Hello,

I'm having problems with my wireless connection going down using the driver that's built into the knoppix 6.4.4 kernel. It generally will stay up for a few hours then it no longer works, and I have to remove and reinsert the connector, or even reboot the machine. Lately, it seem that a full reboot is typically what is required. I had similar, but somewhat worse, problems with Mint 10 as well. On the other hand with Lucid Puppy 5.2, it would stay up for a couple days.

When the connection goes down, I don't get the prompt to use the credentials stored in the keyring, instead I get the Wireless Network Authentication Required dialog.

I'm using older, two part firmware, as is describe here:
http://wireless.kernel.org/en/users/Drivers/ar9170

With Mint 10, I tried both the old and new firmware, it was pretty much the same either way. Puppy used the 2 part firmware, so that's what I've tried with knoppix.

I thought that maybe the reason that Puppy was working was that it used an older version of the kernel (2.6.33.2), but I've tried to use knoppix 6.2, which is has a slightly older kernel than Puppy and it was pretty much the same.

Here's where it loses the connection:

I got home my connection was down. I tried to log in using the saved credentials (it wasn't asking me to use the keyring). It failed, I tried removing and reinserting the wireless adapter several times, but it didn't work:


Running iwevent last night to see if I had anything interesting, my wireless connection stayed up all night for the first time. I tried it again this eventing with the following results. Any idea what's up with the segmentation fault? It appears to coincide with it losing the connection.

I guess I'll try the newer firmware, but any ideas as to anything else I should look for? I have a system log of Mint 10 losing the connection too, it looks pretty similar.

I also have logs of it loading and connecting to my router after a reboot with knoppix, etc.
