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.

I am passionate about Systems Administration. I like to face new challenges and test new environments.Windows and Linux Debian boxes (both physical and virtual) are my favourites. I like solving problems related to Windows Server roles and services as well as Linux but some distributions in particular. I'm not considering myself as Linux master but surely, I always do my best to fit the needs. On the other hand I consider myself as a Windows Server Professional and in terms of WS and Windows Desktops I always follow best practices, good advices and opinions from other admins.

    Seems OK after uninstalling the update and reinstalling the driver of the MT7603E wifi card.

      I’m glad it helped you. That card gave us a lot of problems in our HP laptops. On later edition of HP laptops that card was replaced with other brand 🙂
