Hi guys. For absolutely ages I've been having connection issues with my xbox one, causing horrendous in game lag which completely ruins any game, but after months and months I have FINALLY found a fix and it's absolutely nothing to do with your internet..!
For those of you who recievethe speeds, but suffer from lag, follow these steps on you xbox one console. This has made my connection as smooth as a baby's bum, and I hope to god it helps with yours too!
Sign in to your xbox live account on your xbox one,
go to settings >> all settings>> Disc & Blu-ray >> Persistent storage >> Clear persistent storage. Do this 3 times.
THEN:
Back out to the settings page >> network >>network settings>> Test multiplayer connection..
When it comes up with "EVERYTHING IS GOOD" Don't exit the screen, but hold down the off button for 8-10 seconds so your xbox completely shuts down. take out all wires from the back of your xbox and put a 2 minute timer on. After two minutes, put all wires back in, turn your xbox on, and the problem will be solved!
Please try this guys if you are suffering from in game lag on the xbox one console because I can't stress enough how many different things i tried before figuring this out. Don't miss any of the steps out and please let me know if this helps you! I hope it does as much as it's helped me! Cheers guys, Nathan.
