Disconnecting mid-game

I keep disconnecting mid-game. (After 5-15min)
We have two laptops on the network, and both have the problem.
On another network everything works out.

I tried to disable the routers firewall and reinstalled the faf client.

Everything worked out and suddendly without any changes to the setup the problem keeps happening every game.

Thanks for helping me out.

This is nearly impossible to fix, without knowing your whole network environment. If it runs with the other network, then why not use that?
