NO. And No. And No.. on everything here.
If your connection can't handle BOTH multiplayer and streaming then you need a better Internet connection. It isn't the WIFI that is the problem, it is the CONNECTION to the router; think this way, you can do 100MPH out of your driveway, but if the Road to your driveway is only 5MPH it doesn't matter how many 'driveways' (wifi adapters) you put on your house (computer) your still only 5MPH to get to the store (streaming music / multiplayer game).
You misunderstand me, I'm not connecting to the same router/internet line. Both are entirely different lines from 2 seperate internet providers.
To me this sounds SUSPICIOUSLY like your sucking off two 'neighbors' Wifis, because no business / personal home would have "two different wifi signals " to "2 seperate internet providers." That is overly costly and makes no sense. So I am calling a flag on that.
To simplify what Bill001g is saying below:
NO. Think of Wifi or Wired connection like a cell phone in your hand. While you can hold one cell phone to one ear and talk to Person A, you can physically hold # 2 cellphone to the second ear to talk to Person B the problem is when all three of you all talk. When both A and B both talk at the same time you can't tell who is saying what, and conversely when you 'speak' both A and B think your talking to them separately. So communications break down very quickly and you can't hold the 'conversation'. SAME THING for Windows, it can't talk to just ONE Wifi, and it can't understand when both Wifi talk to it at the same time. Much less WHO is actually talking as both say the same 'name' (I am Wifi, speak to me).
As for the Router-multiple connection, basically at that point your trying to "load Balance" (as he said) and getting very technical / high risk of failures with trying to 'force' a third seperate device to do the work your asking (and are very COSTLY) then cable connect that to your PC (no you couldn't redistribute the two wifi signals as wifi signals, that means you have to have ACCESS to both router's Admin functions and setup things as AP/Repeater Bridges).
