Check /var/lib/NetworkManager/NetworkManager.state. I ran into a bug where "NetworkingEnabled" would get set to false as part of the suspend process but some issue (race condition? I'm not sure.) prevented it from getting set back to true. This resulted in an nm-applet (Actually, the KDE version) responding, but not connecting to the local AP and auto-connect also failing. Restarting the applet, restarting the NM daemon, and fiddling with the kernel modules still didn't affect the relevant variable in state, so I wasn't able to get on the network. I eventually wrote a wpa_supplicant config and was able to bring the interface up manually to search for matching issues. Turns out a reboot or another suspend/resume cycle probably would have resolved the problem. > Take laptop to kitchen, reboot at some point, and boot-up process is > slowed down while dhcp tries to obtain an ip address.

Yeah, that's probably going to happen if you have an "auto eth0" line in your /etc/network/interfaces. I ended up dropping both eth0 and wlan0 from my /etc/network/interfaces because on this system it just makes more sense to use NetworkManager. (I have other systems where NetworkManager is banned because it acts as a network mangler for non-trivial network configurations.) If you think you need eth0 in /etc/network/interfaces for your NetworkManager to work properly, you still might drop the "auto eth0" line (but leave the "iface eth0 ..." line(s)). HTH. I'm on mostly Squeeze right now, but the installation is originally Lenny that I configured to allow a mixture of stable/backports/testing/unstable/experimental. -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
