Feisty 32-bit, 2.6.20-16-generic with ipw3945 and e100 on a Sony Vaio VGN-FE41Z.
Using just the ipw3945 wireless connection on a WPA2 network. After resume from suspend NetworkManager reported no network devices. Restarting NetworkManager didn't seem to solve it. The solution was to use mlaverdiere's method dated 2006-07-05 to stop NetworkManager during suspend and start it during resume: https://bugs.launchpad.net/ubuntu/+source/network- manager/+bug/40125/comments/43 These methods all failed to solve the issue: 1. Adding max_replies_per_connection=512 to /etc/dbus-1/system.d/NetworkManager.conf 2. Adding dbus suspend/resume scripts (with varying priorities) as per John Cooper's post 3. Disabling Wireless Networking from the nm-applet prior to suspending Doing a suspend/resume cycle whilst running NetworkManager --no-daemon reports: NetworkManager: <information> Activation (eth1) successful, device activated.
