I am connecting via a wireless router well pc is connected by a network cable. The odd thing is the N800 dosent show up as an attached device but I can browse the net over the connection and can see shared files on the pc ( sometimes and it takes forever to find them - the directories are populated in slo-mo). I left my treo in my pocket and carried my n800 about today left it on and gvm minimised and used it regularly during day running a couple of skyscape references and it went fine- battery still showing 6 hours when I got home ( I did turn bluetooth/wifi off). Very pleased.
