Is it Possible to host a game with a wireless connection?

I've found out that i can only host a game with the PC that is connected to my modem that is connected to a router and shares internet with my other PC.
And that PC won't host.
So i ask myself can we host with a wireless connection?
Hope someone can tell me thanks!

I don't really understand how your network is...

One PC "A" is connected to the router and other PCs "B" and "C" are connected to "A".

And you want to know if you can play aom on gameranger on PC "B" or "C"??

I think only "A" will be able to play correctly because you can only forward UDP 16000 port to 1 device.
Just try with other computers.

About wireless, yes it's possible... I use wireless to connect to my router and all my internet settings are exactely the same as if I connected with wire.

it is possible cause thats what i do. it could be yr firewall
