I recently installed Fedora 8 on my self-built Compal IFL90 based laptop (I've been running Windows Vista on it for a year). To my pleasant surprise, my built-in Intel PRO/Wireless 4965 802.11 a/g/n adapter worked right from the start, connecting to the non-secure version of my university campus network right away. I could surf the Internet, install packages from the Internet, and so forth. Thus, I installed no other drivers and made no additional configurations.

After setting up some desktop features, installing my graphics driver, and so forth, I opened the terminal and used "yum update" to install the 250 or so updates available.

Along the way, I went from kernel 2.6.23.1-42.fc8 to kernel 2.6.24.4-64.fc8.

Upon rebooting, my graphics driver failed to work (it was an easy fix, and not a problem), and my wireless adapter "wlan0" failed to connect. Displaying the following message as all the devices started up during boot:

I don't think that it worked when booting into the old kernel either. Note again that I have not installed ndiswrapper or anything to setup my adapter, it just worked by itself after install. I'm no expert, so some well-explained, detailed help would be appreciated. Thanks.

I believe that this card uses the iwl4965 driver, which depends on Intel-supplied firmware ("ucode" in Intel-speak). The firmware resides at http://intellinuxwireless.org/index.php?n=Downloads, but is normally automatically installed as part of the kernel installation process by Fedora, by some rpm or so.

Please check that the firmware versions that you actually have match the ones that the new kernel driver needs. There are a few versions out there, and my first guess is that your firmware version didn't get updated when the kernel and with it the driver did. On my system the ucode gets installed into /lib/firmware, but it might be different for yours. I see version 4.44.1.20 on my systems that have that card.

Hope it helps,

This is the same problem i am experiencing with my edimax EW-7128G. After i yum update and get use this kernel, my wireless ceases to work.

How can i check the firmware? I'm still new to this, but wasn't too sure about your instructions.

any help would be most appreciated!!!

Thanks
