Xbox One Rainbow Six Siege NAT Type

M.i.G

I recently got an Xbox One and started playing Rainbow Six Siege with an "open" NAT type. It was connected wirelessly with no problems. 

Then randomly one day my NAT type went to "Strict" and I have not been able to change it since. 
I do a speed test on my laptop and get 70Mbps back so this is very confusing to me lol

I've tried connecting directly to the modem but it does not fix the issue. 

Any tips on how to fix this would be appreciated.
