Wifi hates each other

[quietshift]

Me and a friend have an interesting issue when it comes to connecting to each other, when we are at college we can group together and do missions (with my strict -NAT that doesn't go away) but when we come home to our families, we cannot group together, we can form a squad but when we go into any missions, one of us will basically not be connected. For example, if I'm host or someone else is, we can go into missions but my friend will be lagging so much that it takes minutes for his character to move and perform various tasks but he will experience whatever else happens correctly that he doesn't do. If he hosts, I cannot connect to the mission at all. We are not sure which internet is causing this issue but this doesn't apply just to warframe, games like starcraft, monster hunter, and overwatch gives us these kinds of issues.
