Having problems hosting!!!
 

I am behind a Linksys router... Cable connection

My hosted game shows up on gamespy no problem so I have my ports open. I can host like 4-5 people at low ping rate, then when like even one more comes in, it shoots up to 999 ping...

I don't understand what's goin on??

On Gamespy it shows the room ping at 1ms.... I don't know if this shows as a problem.

I know my comp should be able to handle more peeps...
2.4Ghz PIV
768 DDR 2100
128mb GeForce4 Ti4200
120GB 7200rpm 100UDMA HD

Any help will be much appreciated! Thanks!
