Lanplay doesnt work but online does?

[tootough]

First off...

I have:
PIIIE 933mhz
Currently running Win ME but upgrading to xp soon
256mb pc133 sdram
64mb geforce 4 mx 420
40gig hd
3com ethernet card

Okay when i try to play savage online it works great.... its awesome... but at lan parties my computer freezes and cannot even load the menu screen... but if i unplug the cat5 cable... it will load the game for me... but i use cable at home so it works fine?

any ideas?
