John,
In addition to a recent enough kernel, which you have already, you need the current 4965AGN bits.? If your updates don't have the current version, you would have to follow steps shown on sourceforge.
As I said, it works only?with 802.11g access points, as far as I can determine.? It can see a,b,g,n but won't connect to b.? I have doubts about a and n as well, although I hever had the credentials to connect to any of those.
I don't know any data on marginal signal performance, or whether antenna improvements could be applied to the 4965AGN in T61.? I see access points over 5 miles from my home on the list, not strong enough to connect, and I?don't have the problem?with my neighbors' strong access points interfering that I did with the T40 Intel 802.11b wireless.? g access points are only now beginning to show up in my residential neighborhood.?? I have tried to connect to Starbucks at various distances, but I think they are linux unfriendly.
Tim

Evidently with Gutsy (kept up to date) I have a later kernel than you
do:
jjj@Devil7:~$ uname -a
Linux Devil7 2.6.22-14-generic #1 SMP Tue Dec 18 05:28:27 UTC 2007
x86_64 GNU/Linux
Yet I still have the "hanging up" problem with the 4965AGN. Maybe it
was fixed in your kernel and broken again in mine. Who knows?

My house is wired for gigabit ethernet, so I never use the wireless at
home. I use it only when away from home, mostly at the university. The
4965AGN does work there, but I get random disconnects, especially if
I'm in an area with poor (less than 50% or so) signal strength.
Unfortunately, that pretty much describes the entire library building.
And as a mere student I have no control over what kind of wireless
equipment the university decides to use.
For a workaround I just use a Netgear WG511 v.A PCMCIA card and leave
the 4965AGN turned off in the BIOS. And push come to shove, the library
does have a limited number of private study rooms with ethernet jacks.
I'd love to help the open source community fix the problem, but I know
nothing of how these things work and I don't have time to learn right
now. I'll just contribute in other ways and wait and watch for a fix.
