I saw an earlier post thinking that it would help, but it didn't. The post was for turning the Wi-Fi capability on, which is what I needed, but in the command it shows that it's already enabled, just disconnected. I tried putting "connected" at the end instead of "enabled", but it told me it was invalid. The computer already has Wi-Fi capability, it just got messed up in the switch back to Win7. The computer is a Toshiba Satellite U305-S5077. It was bought used with Win8 on it and the sound card broke (or stopped working). The toshiba website only had drivers for Win7 and Vista for that laptop so I went ahead and downgraded to Win7. After that, the Wi-Fi went out and the sound is still gone. I re-tried the Toshiba.com support drivers but it failed, and failed, and failed. I have pictures of the problem but since I'm new to the site I'm not able to show it.
Also, if you have any knowledge on the sound issue, that would be very much appreciated! :)
