Works Great
My system Config as follows:
Vista and some Linksys routers/firewalls = stalled sessions (Workaround)
There have been some reports on the Internet about networking problems after installing Vista. If you are having trouble getting IMAP/POP3 mail or trouble using RDP with Vista and are behind a Linksys router/firewall, try this under Vista:
“netsh int tcp set global autotuninglevel=disabled”
If your networking problem goes away, it is due to a bug in MANY Linksys devices.
So far, most reports are coming from RV042 and RV082 devices, but it seems pretty widespread in general.
Linksys has a beta firmware available for the RV082 that fixes this problem.
Once you install the updated firmware, you can re-enable auto tuning with:
“netsh int tcp set global autotuninglevel=normal”
Thanks to my friend Tom for pointing this message thread about it here.
I’m sure other devices/stacks might have trouble as Vista gets deployed more widespread. Time will tell.

also this
I GOT IT!!
ok, its a VISTA / LINKSYS problem
with the new vista networking and its TCPIP Scaling (self tuning)
it appears that it exposed a bug in alot of LINKSYS Routers
(many complaints on linksys forums)
I have a RV042, Linksys already has a beta firmware for the RV082 which addresses this issue…
when i turn of its internal firewall, Everything is fine…
I didnt want to loose some of its protection
so…
at a command promt
netsh int tcp set global autotuninglevel=disabled
that will disable vista from messing with packet size
when the router gets new firmware… ill do
netsh int tcp set global autotuninglevel=normal
this is a good FYI…
