I've got a Dell XPS M1530 with Intel 4965 AGN wireless card (dual-booting Ubuntu 10.10 and WIndows 7) connecting to a D-Link DIR-855 (simultaneous dual-band router). The router serves two SSIDs: one on 2.4 GHz, one on 5 GHz.

When I installed Ubuntu 10.04 (clean install) on laptop, both 2.4 GHz and 5 GHz modes were working fine. However, since the upgrade to 10.10 I can't connect on 5 GHz, but can on 2.4 GHz. I'm 1000% sure I use correct passphrase, and the router doesn't use MAC filtering. I can connect on 5 GHz from Windows 7.

Here is an extract from daemon.log:
