XBOX LIVE ON XBOX ONE MULTIPLAYER ISSUE WITH COMCAST ROUTER

XB1R Hypnos · Jan 5, 2014

Setting up port forwarding or the DMZ is for specific ports. The firewall is for generic traffic. If the the firewall is seeing the traffic as harmful in any way it's going to deny those packets from being properly sent and/or received. If the firewall is
set to low it should still protect against the most common forms of attacks, however the firewall on a gateway/router isn't specifically designed to protect against malware or viruses. The firewall built into windows, or a software firewall of your own choosing,
will do that job.

I lowere my firewall settings. I can now connect to MP successfully. However this is not ideal as I have many windows machines on this network. Also this begs the question what are port forwarding rules and the DMZ for?

Ok, perfect. So with that being the case our next step is to attempt a few things, some of which you may have already attempted. If they are then we'll skip on over them or possibly change the way they've been set up.

Currently do you have the Xbox One set up in the
DMZ or with
Port Forwarding?

Have you set up a
DHCP Reservation for the Xbox One console so it is being assigned the same IP address consistently or do you have the Xbox One getting it's IP address automatically, or even possibly have you set the IP address manually on the console itself?

Depending on the current set up for the previous 2 questions, my next suggestion would be to adjust the

Firewall on the TC8305c. For testing purposes our first test will be turning the firewall off completely and running the Test multiplayer connection again. Be sure to perform a full

power cycle on the console before testing, after setting the new settings on the TC8305c.

I found a new thread with this new error code.. I'm going to try those steps...

Disable upnp and then re enable it. Reset gateway. Then hold down the front power button on the Xbox for ten seconds. You will see the green splash screen like you are starting it for the first time. Problem should be fixed now.

Alright, thanks for that information. Now onto the good stuff. I know from your previous posts that you have Comcast as your ISP, but what specific equipment are you connecting to? Are you connecting with just the equipment provided by Comcast or do you
have additional equipment such as a router, switch, wireless extenders? I understand that it's not working wired as well, are you getting the same "were not sure what happened" message when testing wired? Also, are you currently attempting wired or wireless
so I know which way to troubleshoot this.
