Alright, I found out the real problem. It worked at home but not at work. Then we picked up a wireless router with a Sprint broadband laptop card to give us wireless access to the cell network, and that worked too. After talking to the networking guys, my work's wireless controller was blocking the ports we needed to connect to the accounts, which would explain why we could connect to the internet and Skype, but not Google or Jabber. Thanks for all your posts. advice, and help.

I have had the exact same problem several times in Europe - I can get the internet to connect, but presence stays red. When presence doesn't work I usually just manually start up Gizmo. Sometimes it will connect even though presence isn't working. If Gizmo connects I am good to go. If Gizmo won't connect - I find another internet connection.

I have the same problem with the flashing green to red. In my case while the tablet still says I'm connected to a network, I can't load any webpages. My only solve is to disconnect and reconnect to the network, and usually it works. If it stays in the "limbo" state, it drains my battery.

One thing I did to sort of fix the problem was set the timeout on a LAN when inactive to 10 minutes, and for the tablet to search for an internet connection every 5 minutes. So if I'm away from the tablet and it connection gets messed, it will disconnect and reconnect, usually fixing the problem.
