Problem with Intel Wireless (iwl4965) on HP 8510w laptop

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Let me start off by saying, it doesn't appear that the problem is with the wireless directly, but rather the negotiation when trying to connect. Once I get connected everything works fine. I seemed to have the best success with the kernel that shipped with F9, however, it wasn't even 100%, but more than 3 kernel updates later, things have only gotten worse. It usually take 6-14 tries to get a successful connection.

Some background info:

HP 8510w laptop with Intel 4965 wireless
D-link wireless G router
WPA2 security/passphrase

I would suspect the wireless router except it works fine with this laptop in XP and my wife's laptop (broadcom w/ native driver+firmware) in both XP and F9 every time. I've watched /var/log/messages during the attempts but I don't know what all it is telling me, if anything useful.

Below are two excerpts one unsuccessful and the other successful:

This time it took about 8 tries... Anyone else have this problem or suggestions for a fix?

Thanks,
