Hello 
I am soon to be getting an Xbox One and wondered if the link above still fully applies or would there be some things that I would need to differently?
Any help would be greatly appreciated as I really enjoy playing with friends but really hate the lag!
The dude’s an expert so of course his tips still apply. I’m getting an Xbox One later this year too!
Yeah but my question is would there be some stuff I would have to do differently or would it still apply verbatim?
First thing that popped into my head was different console, different porting but I don’t know diddly! Lol
There can be only ONE 
The only difference is that if you choose to forward ports, the Xbox One uses three additional ports.
More info here:
Xbox Support - Network ports used by Xbox Live
Xbox Forums - How To: Open NAT to resolve multiplayer and party problems (updated with Xbox One info)
That said, port forwarding/NAT issues won’t really affect connection speed. Which games are you lagging on, and do your friends live near you geographically?

Thanks for the links, I shall check them out.
Which games? That would have been Reach and since release Halo 4 if that’s what you mean.
Game type is 90% of the time, slayer or big team slayer. It seems to do it across all types tbh
Friends are from all over, some were literally a mile away, some hundreds of miles away and some thousands of miles. Different combos of say just myself and a local, or just myself and an American(I am English) or a mixture of all of them still seems to have the same effect. At first I assumed it was because I was playing like a turnip but after three years of it I think not. Play alone and it would be super rare for me to ever go negative, am nearly always in the top three, play with friends in party and my best scores are the equvalent to my worst scores when I play alone. Very occasionally it feels like it lets me play normally.It’s as if I’m half a second behind normally.
I have been with four different ISPs now (not because of this but due to other unrelated circumstances) and every time same issue. I’m currently on 100 download speed (which ain’t that important), 6 upload and a ping of between 9 and 11. I can play over a mobile broadband connection alone and it feels better than playing with friends on my current super duper broadband.
Play alone and I’m king of the castle, play with friends and I’m toilet.
All of which is very frustrating! We all love playing with our friends but I have to avoid them occasionally just so I can keep my k/d at something reasonable.
I am hoping the link I posted, along with yours would sort that out.
If it doesn’t I am just going to have to be very offensive to everyone on my friends list!! lol

Both Halo: Reach and Halo 4 use a P2P networking model in which one player’s Xbox 360 is designated as the “host”–the authority of the game–and all other players, “clients,” get their data from it. So if you’re a client connecting to a host that is close to you, your ping will be low, which means less lag. If you’re connecting to a host that is on a completely different continent, your ping will be much higher, and so you will lag more often. What’s worse is if you’re connecting to a host that not only is far away from you, but also has a slow connection.
Based on what you’ve described, it sounds like your problem is really that sometimes when you play with friends, the game chooses a host that is very far away from you. This would cause you to lag a lot more than the other players in the match.
The good news is that future Halo games, including the Master Chief Collection and Halo 5, will use dedicated servers. This doesn’t eliminate lag in global online play, but it does make it a little more bearable.
Another possibility is that your friends’ invisible matchmaking TrueSkill ranks are higher than yours, so when you all play, you play against higher-ranked players than normal. Believe it or not, even Halo: Reach has skill ranks; it’s just hidden from players and only used to make fair teams.

With regards to host & clients, wouldn’t that also be the case for every game? I can be in a game with people globally but I’m not in party and it’s fine (though the crucial thing would be knowing if I was the host in that case I suppose).
I had heard this about dedicated servers but, in hindsight, more than a little dumb of me not to connect it with my party lag issue! lol
I refuse to acknowledge your final paragraph. -Yoink!- I just did! lol There is only a few friends who are better than me (greatly so as well, which is annoying) and if I play with them my score is an equal level of badness as if I play with my worst buddy. That is of course only based on my assesment of skill level though but still, can’t be tooo far wrong.
Here’s looking to a far less lagged out Haloing future!
