Wireless Limited Access Problem!?

[Sharni]

Just bought a new laptop With windows 8. ( sony Vaio Model" SVF152A29W ) I got it about 3 weeks ago, And the wireless Internet keeps going onto limited Access and cuts of all my internet. I have to keep repairing it which takes about 3 minutes for it to finally go back to normal then it does it again 5 minutes later! it's really annoying. It has nothing to do with my internet because everyone in the house is using a laptop and they do not have this problem! Please help!

p.s. i have contacted Microsoft about this problem too, but they are trying to charge me $99 dollars just to get someone to look at it!
I've noticed a lot of people have this problem. But if you know how to fix it please dumb it down a little for i am not a computer wizz thanks.
