Alright, so as the subject says I am having only one problem. I am not even sure it is related to the 1.21NA firmware update which seems to be working fine for me. I have two computers, a PC and a laptop, and my Xbox 360 hardwired to the router. I have not had to reset/reboot my router at all since I bought it back in early 2008, except for when I updated the firmware and changed the settings in the router. The only problem I am having is related to my Xbox 360. Actually it is exclusively with Halo 3 and ODST. Every game I play on my 360 over XBL has no problems with online play, except for these two titles.
Now, when I am playing these games it will be going perfectly fine. No lag at all. Then all of the sudden I will lose connection. I look at my router and it hasn't reset or rebooted. I look at my modem, which is a Motorola SB5100, and the send light is blinking. It is always solid when everything is working fine. So I have to reset my modem, but not the router oddly enough.
So I guess my question is, what in the world is happening? Is this an issue with my DGL-4500 or my Motorola SB5100?
Router settings: WISH turned off. Wireless set to N/G, WPA2, AES cipher. Dynamic Fragmentation is turned off. Gamefuel is on with rules for WoW and 360. Ports are forwarded for WoW and 360. SPI is off. NAT is set to Endpoint Independent for both TCP and UDP. All ALG's are off. I have the PC, Laptop, and 360 with DHCP Reservations. UPnP is off. WAN Ping is off. WAN Port Speed is Auto 10/100/1000Mbps. I have Special Applications set for WoW and XBL.
I don't know what else to list for the router. That is everything I can think of that would be relevant to possibly creating the issue at hand if it is related to the router at all. Does anyone have any idea what could possibly creating this issue?
