Update to 5.10.91.9.3

Updating to 5.10.91.9.3 (manually) fixed many various (mostly post wake-up after system sleep) issues I've had with this driver, in both Karmic alpha and beta.

The symptoms included many, many disconnects from a stationary laptop.

Please consider requisite for release!

The (manual) update indeed fixed the issue of dropped connections for me as well.
I second the request for an update in karmic.

You have my vote, too.

I put together a bcmwl 5.10.91.9.3 package for Lucid. It’s currently building in my PPA:

how can i update to 5.60.48.36+bdcom-0ubuntu1 in karmic?

I have had nothing but troubles with this BCM4322 wireless n card in my macbook pro 5,5; difficulties connecting, periodic system crashes, tons of dropped packets and overall poor performance (1-2mbps is my typical throughput)

I manually updated to the 5.60.48.36 driver by downloading from the Broadcom website (http://www.broadcom.com/support/802.11/linux_sta.php) and renaming all wl.ko files I had to wl.ko.orig, then copying the new wl.ko driver in their places (you can follow directions in the readme.txt on the site)

So far, I've been able to do a few sleeps, connections are much easier and the performance has been much, much better. Most importantly, no crashes so far.

I hope this new driver makes it into the repositories soon as it already seems to be a significant improvement over the previous version, especially for those of us who have no other options (I can't use b43 or ndiswrapper)

As you can see above and at http://packages.ubuntu.com/bcmwl-kernel-source , 5.60.48.36 is already in Lucid. If you need a fix for the bug in previous versions of Ubuntu, please follow the instructions for “How to request new packages” at https://help.ubuntu.com/community/UbuntuBackports#request-new-packages .

It seems broadcom is really not a good choice of wifi card... I never
had issues with atheros or intel...... lesson learned.
