frequently drop/reconnect on a variety of ThinkPads running the Intel 4965 and
Intel 3945 wireless chipset.

This behaviour has been reported on Ubuntu 8.04 and 8.10. It likely the same in 9.04.

Unfortunately, the fix for Fedora you link to is private, which mean we cannot access it.

Is there any public record of what the fix involve?

Hi Etienne - Patch details are in this public ticket:

John,

The Fedora bug you list is also private. You sure you link the right bug?

[Murillo Fernandes Bernardes (mfbernardes)]

The behaviour is the same on 9.04 and 9.10.

Adding this patch http://cvs.fedoraproject.org/viewvc/F-11/wpa_supplicant/wpa_supplicant-assoc-timeout.patch?view=markup to 9.10's wpassuplicant (0.6.9-3) I could get reliable wireless using LEAP.

03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61).
