Connection Problems

[Vyx]

When i try to connect to counterstrike it will let me get a server list then wont let my computer get on the internet anymore, after that i have to turn off my cable modem then turn it on again to get it to let me on the internet. This problem also occurs when im using shareaza? anyone know why this might be happening?

are you using a router to share out internet?

what is shareaza? (cause im to lazy to search)

any kind of software firewall running?
