Poor connection/ Limited connection whenever games are ran

[kozato]

All computers in the house are able to connect through a wireless location anywhere without poor signal.. One device, the laptop, can hold a connection but will instantly lose it (And the icon in the bottom right corner will say "limited") Within a few minutes of a game running. The connection is gone. This didn't happen several days ago and it is a huge problem all of a sudden. Not a single other device is experiencing this. We've checked for intel wireless drivers, updated them, gone to old ones, still nothing. The wireless network adapter for the laptop is this: intel wireless n 7260.
It hasn't caused any problems in the past, but now gaming for a few minutes is simply impossible. any solution for this? The laptop is windows 8.1, 64 bit.

What other device is running games? How many devices are connected at once? Does it restore when the game is finished?
