Multiplayer issues - can't find the lobby

[KenWayneKazama]

Hello, everybody!
I need help with fixing this.
I was looking for a clue how to fix that, but still i didn't find it.

So here's the situation : I wanted to test if i could play multiplayer on Valkyria Chronicles 2 and Ace Combat : Joint Assault.
So, the computer was connected using the cable, and the laptop has been connected via WiFi. I started ADHoc server on the Computer, then i created a lobby in Valkyria Chronicles 2, and i couldn't find my lobby on the laptop. Same goes when i started the sever on the laptop and was trying to join using computer - can't see the lobby. I've connected them both with the cable, but still the same thing - can't see the lobby. And the same problem goes with every game i was trying to test.

What's the problem? Did i do something wrong?
