Net on W7 wont stay connected, but Fine on XP

[Caiterz]

Ok, heres the situation..

My computer - HP Pavilion P7-1010. Windows 7 64bit home edition..

My Laptop - HP mini 1000 with XP

I play this game, Trickster Online.. and they have a "stay connected for 100+hrs" event..

On my laptop with XP, it will stay connected until I Disconnect it.

On my PC, it will stay connected for like 5-20mins, then log everything out. EVEN if i am still using the internet.. (its not Idle!)

I've tried the following:

-Turned off "Disable this to save power"
-Turned all my Windows power settings to "never hibernate, no screensaver, etc" even no shutting off of the monitor.
-Tried Wireless and wired, (Both same results)
-Reformating the computer to get rid of any rogue programs messing the net up
-Updateing drivers and Windows
Is there maybe some weird option in the settings for Windows 7 broadband card?
or maybe some weird setting in windows 7 to cut my net after so long?

Ive searched everywhere and cant find anything

THANKS SO MUCH Also - Heres some info http://ompldr.org/vYWFtbg

Welcome to SF,

I'd start disabling Start up Apps and Services that are not being used. You may do this from Start and type msconfig.

Are you using a 3rd party wireless software?
