: Unstable Upload Speeds on 2 OneX's

Found this Multiple XBox connects.

Hey guys, I wanted to chime in here. I am having the exact same thing. My Xbox one X n my wives as well as my 3rd (yea we got 3) all have this issue. My pc gets 800mbs with 40 to 50 upload. My Xbox as get 300 mbs with uploads at 0.14 to 3mbs. I literally
have changed my network switches, got a new router, n just now set up a new modem directly from isp. No change. Ive had techs out the last several months helping me isolate it N it's all from the Xboxes currently. Like the OP, I've got port forwarding and
did everything else. I also have CAT6 thought my home.

I just want to let you know it's more widespread than you know n my wife n I are having issues playing together as well.

Please either give us another port to open or see what's changed in your updates. If u need more info I'll gladly assist cause it's frustrating.

Thanks

I have a Netgear Nighthawk R7000. Not quite the same model.

But am able to run two Xbox Ones and an Xbox 360 on it at the same time with open NATs and without needing to use static IP's, port forwarding or DMZ.

You actually should not be using the DMZ and port forwarding with two xboxes. You should be using UPnP entirely.

The Xbox under the DMZ may still be using the same Network port as the xbox using the port forwarding and conflicting with each other.

But with UPnP your router should automatically give both xboxes different network ports so they don't conflict.

What you should try doing is switching both Xboxes back to using Automatic IP addresses then remove all DMZ and port forward setting from your router and make sure UPnP is switched back on.

Reboot both router and xboxes after doing this.

Then check your NATs. If they are both open then it should be fine. If not you can tell one of the xboxes to use a different network port by going into the xbox advanced network settings then go to Alternate port selection and set an alternate port.

I am having the very same issuse and I agree that an update is to blame as it started happening around the same time that yours did. Cox has come out and did everything that they came do replaced lines modem and wall jacks everything else in the house gets
300 down and 30 up the xbox one x gets 300 down and anywhere from 1Mbs to 3Mbs I have spoken with Microsoft and did everything that asked me to do to no avail did connected everything from the xbox one x and still no joy. I cant stream and games lag. So this
is now been verified that it isn't a problem with my IPS. If you find a fix please let me know

Well, I'm glad
Your reddit post has got some attention but as you are in the Alpha ring your OS preview may have something to do with this issue. It would of been less time consuming if you had mentioned you are in the Insiders already.

You would of been directed to the Insider forum earlier.
