I recently purchased a Toshiba Satellite C55d c5251 with windows 10 preinstalled but the wifi drivers do not support hosted networks, which I need in order to use my computer as a hotspot. I've been looking for them but haven't been able to find them. Is this
a Windows 10 thing? Because one of the reasons why I purchased the new computer is because in my old one I had hosted networks support with windows 7 and after I upgraded to Windows 10 I lost that functionality and I though it was because of my old computer
but the problem is the same with the new computer and I need to have that functionality. Any suggestions?
