Hi,
Was reading thru the more recent threads and it occurred to me about the Shareport issue(s) that I recall in my own XP Pro setups that the XP firewall keeps flagging the Shareport Software as it attempts to use the firewall to reach the router etc... I have a Canon Pixma iP4500 color printer attached to my DIR-655 (FW 1.21) USB port.
Sometimes my shareport seems to lose its connection for no obvious reason, the little systray icon goes red instead of staying green.... I usually just exit the shareport software and wait a fwe seconds and then re-start it (shareport utility, not the router).
I keep deleting the items inside the XP firewall Exceptions chart, and they keep magcally re-appearing, so obviously something is doing something to the firewall, which is turned off, but not fully disabled. I use a more common 2-way firewall program so I don't even need my XP firewall service running as far as I am concerned.
Just a thought about something I haven't seen discussed...at least that I remember...
