Ok - more troubleshooting results:
1 - upgrading to 12.10 (clean reload) did not help. I still see the same results.
2 - When connected via a wired connection, the connection is long lived and stable. No issues dropping the connection.
3 - switching wireless routers (Amped Wireless R10000G or linksys WRT54G) did not change the behavior. Connection is still lost after ~2 minutes.
