internet disconnects frequently when using windows 7
Hi,
I have a problem with my internet connection while using my macbook with windows 7.
I am using 13" macbook pro mid 2012 with Yosemite. For my research I have to use a program that only runs with windows so I installed windows 7 ultimate 64bit. While I was using my macbook in Yosemite, I have no problem with internet connection. However when I use in Windows 7 side, I get problem with internet connection. Wifi is not disconnecting but I got some yellow triangle on my wifi signal sign, and cannot access to internet.
If I disconnect and connect again problem is solved but after 5-10 min later it happens again.
I changed wifi router but problem still persist.
When i use my school wifi, my internet disconnects once in 2-3 hours.
I installed windows 7 to my macbook, my girlfriend's macbook and other friend's macbook, (all 13" macbook pro mid 2012 - 16gb ram - 256ssd - i5 2.5) all have same problem.
Please help me if there is any solution.
MacBook Pro (13-inch Mid 2012), OS X Yosemite (10.10.2)
