Wi-fi keeps disconnecting itself every 10-15mins!
My 2012 MacBook Pro (OS X 10.7.5;2.4GHz i5;4GB) keeps disconnecting itself every 10-15mins. I have to 'Turn Wi-fi Off' and then turn back on to make it work again. Again this process keeps repeating which is highly irritating!!!! Took it to the store from which I bought and they ask another 200 bucks for just finding the issue! After paying so much for this Mac , I do not have any plans to invest more on this one.
There is one other laptop which has Windows8 and it works without any issues in the same network.I have a Comcast modem.
I have read many many articles on this issues but none of them prove to solve this problem permanently.If anyone else has faced the same and knows the solution please share.
MacBook Pro, Mac OS X (10.7.5)
