MediaTek(Ralink) MT7630E drops connection after installing KB2868725
Well, after deploying and patching our brand new HP Laptops equipped with WIFI adapter: MediaTek (Ralink) MT7630E started to drop connection and finally wouldn't connect at all. Problematic update switches off RC4 algorithm in Windows 7, thus braking the WIFI. Solution is simple, don't install it or uninstall if you have problems. Link to KB
