NAT issues can be quite common, especially if you’re using multiple Xbox One units in the same household. I’ve worked for an ISP for a number of years and from what I’m reading in here, it sounds like there are potentially a couple of problems that you’re highlighting here but they aren’t apart of the problem you’re experiencing on your Xbox One so I’ll break down a few things here that are going to help you get the best results possible for your Xbox experience Apparently something isnt working right because SEVERAL ppl are complaining on the Xbox forums and other websites Ive Hey guys, have you heard of anything about this down load speed patch form November and if this is an actual issue around the MS water cooler? You are supposed to be able to down load faster in the back ground while still running a game/app. It boosts download speeds for people with 100+mps and also a boost for ppl with 50+ mps. Xbox released a patch with an update to Download speeds at the end of November. Go to the Xbox and It never goes over 60 now. I can run a WiFI speed test on my chrome book and hit 120-170 every time. HE said it was Xbox…I didnt believe him… I thought for sure its Comcast. He seemed baffled as well…but… his laptop was steady from 70-170. I even had Comcast come out and put in a new X1 modem, they to were getting random speeds on there lap top plugged straight into the modem. Ever since then I get fluctuating speeds from 48-27- 0.8!! Yes less than 1! For 3 years I had steady 120-170 mps until I moved 1 house over in November 2016. For those of you possibly joining this conversation…I have had this issue since November 23rd.
