NAT type is Open, but I still lag?

Lately I can't go a single game without lag. For my home connection I use my iphone hotspot, which is a terrible thing to use to connect. But it's my only option. It usually doesn't get much lag, but lately it's been unbearably bad. Today, I'm playing on my cousin's connection who has 10 MBPS, and the NAT type is open as well but I still get a lot of lag every same and it's so very annoying. What can I do?

NAT doesn't have anything to do with your connection speed. Open or Moderate, or Strict your connection speed will be the same. Lag just means your internet is slow.

  • Will there be IPv6 to IPv6 NAT after all? I don't like the idea of people on the internet being able to ping, port scan, and easily infect any devices on my home network. With IPv6 someone could ping my iPhone, port scan my laptop, etc. On IPv4 everyone has a single external IP address, and that is assigned to a router which acts as a hardware firewall. Will IPv6 have something like this where you can put all your devices behind a single IP? Will it be the default? Or are we all screwed, set to enter the IPv6 surveillance society?
  • Why does my iPhone 3gs lag to send and receive messages? I have an 8GB iPhone 3GS. It won't send messages. It can take from 3 minutes to 2 hours to send a message and same with receiving a message. I'm using iMessage. It is updated to the 6.0.1. I don't know how to fix this problem because it stops me from communicating with people.
  • Why are modern digital cameras still stuck with the problem of shutter lag? The iPhone has overcome this problem; incidentally, the iPhone's camera is terrible due to the amount of bright eye from the flash aside from the disgusting colour clarity.
  • What causes the iPhone app switcher to lag? I just bought an iPhone 5 and compared to my 2.5 year old 4 it's crazy fast. One thing I noticed was that double clicking the home and bring up the app switcher was instantaneous, and on the 4 it took 2-3 seconds. Although now my 5 is starting to do it. What causes it and is it fixable?
