My roommates and I like to play Diablo III and World of Warcraft at the same time, but we experience frequent disconnects. If one of the machines is in the DMZ on the router it doesn't disconnect when the other two do. I've turned the router firewall off and this does nothing to help. Any ideas? Can I just forward all the appropriate ports to ALL of the computers?
If I plug straight into the modem I do not experience disconnects.
Router model: FR-300RTR (rebranded d-link)
Router firmware: DD-WRT c24-sp2
Router firewall: off
manual port forwarding: off
All machines are running windows 7
