Need help in Non Steam Counter Strike Source!

Okay so i download a Non Steam Counter Strike Source works perfectly plenty of servers to play but the only reason i wanted to play is with my other brothers were all using the same internet same room and such. But for some reason we cant join the same room. I tried changing my ip and stuff still didnt work could anyone help please?

you are still playing from the same IP whether you change it or not... your ISP assigns one IP to your house and you use a router to split the connection. but you should be able to play in the same room unless their server dont allow it or something.

Thanks for taking your time replying to my post i been waiting until someone replied lol kept refreshing my page ahh that sucks.. i hope theres a way
