I'm having this same issue but wasn't aware there was a switch/setting on the router for network or other. I have an HP Laptop running 64-bit Vista, a Compaq Laptop w/XP, a home grown XP Desktop and a WIN2K3 Server. None of these machines; with shareport installed, can see the USB drive when connected to the router. The system tray icon remains red and never recognizes a device was connected. I haven't updated my router so its still running v1.20. I've also tried disabling all AV/SPYWARE, etc apps with no luck. This actually kinda sucks b/c besides the increase range and security, this was my reason for buying this router.
