at first, you can all restart your games and routers once, then try inviting/joining again to see if that helps. it may sound weird, but it can work in some cases. if no luck yet, you can switch the host player to see if the problem is due to network settings. when nothing works, you should go for "port forwarding" as a last resort, to become a more efficient host (port forwarding is the process of opening certain ports via router interface). players who enabled required ports have a higher chance to be seen by others in public server list, too. you can easily find video guides on internet explaining how port forwarding is done depending on your router type. lastly, you should take a look at this community guide, regarding the ports used by WaW's online modes.
