Bug Description
Earlier today, I replaced my Atheros 802.11abg PCI-e adapter inside my Thinkpad t61p with an Intel 4965abgn PCI-e.
I'm running up-to-date 64-bit Intrepid, with 'propsed' enabled.
Linux t61p 2.6.27-11-generic #1 SMP Fri Dec 19 16:29:35 UTC 2008 x86_64 GNU/Linux
I have the backports packages installed.
ii linux-backports
ii linux-backports
ii linux-backports
I have not been able to successfully associate with any wireless access point yet, however.
I see one of two problems... Either:
a) the device initializes, network-manager scans and sees access points, but cannot connect
b) or, the device does not initialize properly and network-manager is not able to see any access points.
I don't know what sends me down path (a), or (b), but it seems to be somewhat randomly determined at reboot.
