Yeah ALL Devices are connected to the Netduma even W-Lan is turned off on the ISP Router.
Yes My NAT Type is Open. On the Speed test it shows me an 22 MS Ping.
PROBLEM SOLVED!
In Call of Duty BOS3 I always connect to the UK Server cause thats the closest one to me.
My Ping is always a stable 45MS I´m always under 50MS which works pretty damn good for me, although i wish they were some Dedicated Servers in Germany but
UK still works!
Since i have a lot bandwith and my Brother and my Mom use a lot of it,
I just prioritized my Xbox One to 100% with share excess on!
Time to game!
