I'm playing GTA V with my friends. I get disconnected. This doesn't happen often, so I worry. Naturally, I go to the Network settings. I have a wired connection, and it says my NAT type is unavailable. It says I'm connected to the router, but I'm not connected to the internet. I look over at my PC, and it's STILL connected! I got into some drama with another player recently, and he threw some threats, which I thought were empty. Is it possible he could have done something? I already power cycled, already did the router and modem unpluggings, and I already tried going wireless. It seems as if the problem is only on my Xbox One. Whenever I reset my router, however, it works for like, a minute and a half before going off again. Whenever I try to sign into my XBL account, I get denied the sign-in without an error message, or an error code, or anything of that sort. I press A on my acct, it pulls up a green loading circle, and then a white loading circle, and then brings me right back to the little Snap screen of the profiles.

The simple answer is, yes. The Xbox One has many features that require more bandwidth such as video and music streaming (as most content is served in higher resolution). However, these services are not required to game.
Services such as chat might require higher bandwidth but only marginally as Codec's, what is used to encode and decode the voice before sending it, allows for higher quality sound to be compressed into less data.
By your description I believe that you do not fully grasp the reason why you are lagging out. Indeed, lag is linked to bandwidth but it is usually not the deciding factor. What is more important is latency- Please check a site such as Speedtest.net to see what your latency is.
Latency is the round trip time of data you send out. Basically, imagine it as a postal service. Latency is the time required for a letter you send to be responded to, i.e, when you hold the reply in your hands and can read the response. This is a very important concept as online servers rely on the responsiveness on all participants. So when the host server detects that you take to long to respond to the packets it sends your way, it will drop your connection to avoid impact on the quality of the game for other players. That is why you lag out.
Therefore, a low latency is what you want. However, latency is only loosely tied to bandwidth. It has to do with the quality of your equipment, if you are on wireless or wired, your ISP, your geographical location, and the location of the remote server. There are more factors that are basically related to the above. So when you play on a server hosted on a different continent, your latency will be higher. That is normal and expected.
Now, sudden drops in latency are usually what cause sudden lag or drop-outs. They are caused by bursts of data that clog up the "pipe". Again, imagine it as a postal service. While on a normal day they can receive and forward your mail in a few hours, during Christmas season they are swamped and will take longer. This is to be expected. Similarly, if you are saturating your connection or equipment with downloads, streams, or similar, your equipment, especially older equipment, might struggle to forward all packets in time and connections might drop.
The tricky part is that there is not always something you can do. If you live in an apartment building that shares a physical line, the other tenants might have some activity that is transparent for you but still impacts your connection. The same might hold for your street as all connections on a street usually share the same physical line which uses the same physical equipment down the line.
One way to go might be to contact your ISP and ask what you can do. They should be able to help you. Personally, I'd advise you look into getting on a connection based on optical fibre. They feature less latency and can carry more bandwidth while alleviating some of the problems I mentioned above. If you want you can take a speed test and post it as a comment, I'll try to give you more streamlined advice.
Your problem is most likely due to the controller not being assigned to your person.
The other controller, even though it has a headset plugged in is treated as belonging to a guest (or other profile if it is signed in) and, hence, will not have access to the party.
You can fix the issue by pairing the controller with your person manually. However, reading more on the topic, it seems that if you have set up Kinect Sign-in, the console will automatically recognise that you picked up a different controller and will assign it to you as you would expect.

It's actually a fairly common problem with xbox live that dates right back to the 360. I doubt the other player has caused any damage or that he even could. NAT issues occur with how your router works, but its a pretty blanket statement for xbox live connectivity issues.

Most of the time its down to uPnP (universal plug and play), especially your xbox tells the router what it needs to do to connect to XBL, however the two do not always interact smoothly resulting in temporary connectivity issues.
