WPA connection fails after suspend/resume

[MikeRussell]

Hi all,

Running 8.04 on an Inspiron 1420 laptop here. My wireless at home is WPA encrypted and I have no issues connecting to it..at first. The problem occurs when I suspend and resume my computer. I can occasionally reconnect, but more often than not I fail to make a connection. I've had this problem using both gnome-network-manager and WICD. I don't think it's driver related, because 'iwconfig' shows the network, but attempting to reissue a DHCP fails. My best guess would be a conflict in issuing a new encyption key? Any ideas on how to troubleshoot or fix this? Thanks.

Yes try connecting from the command line!

Thanks for the quick reply. I've tried 'sudo dhclient wlan0' and I hang when trying to acquire a DHCP lease. It eventually times out an gives me a 'DHCP client sleeping error'.

Did you type the entire sequence with the wpa_supplicant.conf file?
