I have a 2 year old Dell laptop using xfce for the desktop environment and Network Manager network connections. The Arch installation is fully up to date. This issue started a couple of weeks ago - following a fresh boot, I can use both wired and wireless connections. As soon as I suspend the machine and then wake it up again, I lose the wired connection and there is no way to reconnect it that I can find. If I reboot, everything works fine until the next suspend when the same thing happens again. I tried rolling back Network Manager with no luck. I tried replacing Network Manager with Wicd, again with no luck. I don't think it's a hardware issue because tried using a live Ubutnu installation and all works fine. Additionally, my wife has the exact same computer and basically the same software and doesn't have this problem.
Here's some relevant info.
