This has been I can partly confirm your observations, since I often see my driver reporting a signal strength of 0 for seconds. The connection is somehow unstable as my log also reports (NSIS meeting this morning, actually not crowded) Nov 13 10:41:01 kernel: eth1: New link status: AP In Range (0005) Nov 13 10:41:03 kernel: eth1: New link status: AP Changed (0003) Nov 13 10:41:25 kernel: eth1: New link status: AP Out of Range (0004) Nov 13 10:41:26 kernel: eth1: New link status: AP In Range (0005) Nov 13 10:42:58 kernel: eth1: New link status: AP Changed (0003) Nov 13 10:45:18 kernel: eth1: New link status: AP Out of Range (0004) Nov 13 10:45:18 kernel: eth1: New link status: AP In Range (0005) Nov 13 10:45:18 kernel: eth1: New link status: AP Changed (0003) Nov 13 10:45:23 kernel: eth1: New link status: AP Out of Range (0004) Nov 13 10:45:24 kernel: eth1: New link status: AP In Range (0005) Nov 13 10:45:54 kernel: eth1: New link status: AP Changed (0003) Nov 13 10:46:28 kernel: eth1: New link status: AP Out of Range (0004) Nov 13 10:46:28 kernel: eth1: New link status: AP In Range (0005) ... and so on... however, it seems also to depend on the cards firmware and driver, so other people may have no problems at all... Inspite all the problems, it works well enough to get things actually done. > the case in every session I've attended, as well as tonight's > plenary.

I wasn't often successful to reattach to APs after my card was "hi-jacked" to ad-hoc cards announcing ietf58. Setting the essid again to the same value seems to do trick, however, often I see signals of strength 0 (maybe the card is confused then..). Furthermore, it happens often that I don't get an IPv6 address directly after activating the card (maybe the RA doesn't get through). Cheers, Roland
