I have a Toshiba Satellite A500 (laptop) and after installing Windows server 2008 R2 to it I can't connect to any wifi. The problem is that the drivers are not installed correctly. I can connect to the internet with ethernet. I went to device manager (in control panel) and the wifi network adapter is in the "Other devices" tab, when I try to install the drivers it says that it couldn't find any. The network card is a Realtek RTL8191SE-VB. I've already tried to download the drivers from the official website but I can't install them because it says that they don't give support to this operating system. I've already enabled the wifi connections to the OS, but the problem still remains (because it's with the drivers). Hope someone had the same problem and could fix it :D and sorry for my bad english. Thanks!
edit: the network card just disappeared from device manager
