I've been using a MI424WR for about a year. Recently, I picked up a PS4 and I've been trying to play Call of Duty Ghosts online without any success. I'm constantly getting errors related to the network communication (i.e. server not found, connection interrupted, etc.). That said, I thought I might have some sort of port firewalled off, so I tried the following after setting the PS4 to a static IP:
1) put it into a DMZ: FAIL
2) tried port forwarding: FAIL
3) tried UPnP: FAIL
4) used my cell phone data as a test to play: SUCCESS (this confirms it is a network issue)
5) rebooted the system, router, etc.: FAIL
6) spoke to VZ customer support... who tells me this is a technical issue and redirects me to premium support ($90 an incident)
7) changed the game disc: FAIL
8) logged into a different system/different network: SUCCESS
9) lowered firewall settings: FAIL
I've read about DMZ/Port Forwarding issues with the Actiontec MI424WR, but VZ customer support won't do anything about that. I'm irritated that after following VZ guidance for enabling the DMZ/port forwarding, I'm told I need to call a support number and pay money in order for them to potentially tell me that the unit is defective.
Both Sony and Activision tell me it's a network issue. Is there a way to test the DMZ/portforwarding? Any help is greatly appreciated!
