Double NAT and UPnP issues on Xbox One =

I started having issues when I purchased an RBS40V satellite in order to have a wired connection on my xbox. I started seeing Double NAT issues and was able to fix it by switching the router to AP mode. Shortly after,the Double NAT issues kept returning, even while in AP mode. I was able to temporarily fix this by switichg back to router mode, and then back to AP mode, but it always came back the next day.

Recently I have been recieving a UPnP not successful error on my xbox, and then a double NAT error when I switch to router mode in order to use UPnP. I have searched and have not been able to find others with the same issue as me. I tried with our RBS20 satellite and had the same issues.

Recently, the LEDs on my RBS40V have turned red, but it does not seem any different than how it usually functions, and the same issues are seen using the RBS20, so I don't think the LEDs have to do with this issue.

I also get a moderate NAT type on my PC as well (on games that display it) so it is most likely not an issue with the xbox.
