NAT issues after years of no problems. At wit's end so making multiple posts for attention. ...

I have made this post before, but it has been ignored, so I'm doing the only thing I can think of and making it again. My apologies for any spam, and I look forward to a constructive dialog once someone replies to one of our posts.

We are having a persistent problem with our xbox one. We have had the Xbox one for years, and have never had a problem before, but about 2 weeks ago we started having issues with being frequently disconnected from a party, to the point where multi player
is impossible. It is especially problematic with Dark Souls 3 (though it used to be fine for that game too.)

Chat will cut in and out, and when in a party my status will cycle between normal and connecting and then finally go to disconnected. I will get a message saying "Your network settings are blocking party chat 0x807A1007"

The issue persists for wired and wireless. It also persists if I bypass the router and plug the xbox one directly into the modem. When plugged into the modem we have an open NAT but still experience the same issues.

Here are my latest network performance values and out hardware:

Download Speed 117.3mbps

Upload Speed 5.65mbps

Latency 15ms

Packet Loss 0%

Wireless Strength 100% (when wireless was used.)

Router - Netgear WNDR4300

Modem - Motorola Surfboard SB6121

We have tried everything we could find with router settings but nothing has helped. Also, there were no hardware changes that were made before the problem started and as I mentioned, things have been great for years. So we have tried: port forwarding, port
triggering, assigning a static IP address to the xbox, using DMZ, putting the xbox in power saving mode with UPnP, assigning highest QOS priority to the Xbox, assigning highest QOS priority to the xbox's ethernet port, etc. We have followed all of the steps
on
http://support.xbox.com/en-US/xbox-one/networking/nat-error-solution as well as dozens of other online threads.

We seem to have mainly moderate NAT status when going through our router, we don't know what it was previously since we never had issues before. We can achieve open status by plugging directly into the modem but we have the same issue then.

Connection Issue w/ Multiple Xbox's - Same Connection

Can you also try using one Xbox at a time to see if you still have issues?

For the attention of others suggesting forwarding/triggering etc if the OP is using certified firmware it has been tested by Microsoft to support multiple consoles with an Open NAT without the need to forward anything. It has been tested to work "out of
the box" with UPnP only, no DMZ, no forwarding, no triggering
