LOTR,

I forced the IP address when I upgraded to SP2, I then upgraded LW to PRO.

To cover all bases, I forwarded 6346 to 6349 TCP and UDP.
This is done from the admin screen on the WAG54G.
Done it both on "port range forwarding" and "port triggering" BOTH TCP and UDP.

Probably overkill, but it solved the SP2 problem.

IP address of the WAG54G for those unfamiliar is 192.168.1.1
and the screen for changing triggering is
http://192.168.1.1/PortTrigger.htm

Check firmware version is up to date.
as of today Firmware Version: 1.02.1

Linksys firmware/driver/platform download page
http://www.linksys.com/download/

Still getting the long delay on double clicking the icon.
Can see some features right away, like downloads.
Others like menu and app bar at the top is not visible.
I've got 2Gb RAM and 3.4GHz P4...........

Any other help?

I trust the WAG54G issues help. I hope I help at least someone, as I pulled my hair out with it!.

Cheers

Gazza
