I was running 8.1 Enterprise and decided to try out Windows 10 Technical Preview, I think it was called. Didn't make recovery media. Didn't like it so I downloaded an .iso of 8.1 Pro onto a bootable USB drive using Rufus. The install worked fine except I cant connect wirelessly to the internet. I have no network icon in the notification area or under settings. Troubleshooter just shows that an ethernet cable is unplugged. Network and Sharing Center only shows an icon for the wired ethernet connection but shows no wireless connection options at all. Thought I might have a bad 8.1 iso so I downloaded and installed a second different .iso but still no wireless. Hope someone can please help.Thanks.
