Today I downgraded my notebook Toshiba Satellite C855-S5349N. It was Windows 8 now its 7 I had to erase all the disk and the backup disk too, coz I couldn’t install Win7.
After installed Win7 I wanted to connect into my Wi-Fi connection it wasn’t there any Wi-Fi connection it’s like disabled but when I wanted to enable it none adapter was there.
So I went to manager tools and it was hidden but everything was good installed, but no external devices they were like Ethernet controller network controller and 2 more were there with the yellow triangle, but I didn’t installed any drivers after installed windows 7 coz I didn’t had any driver disk,
Some kind of driver disc doesn’t exist. When you install own OS version you must install every single driver, tool and utility manually one by one.
As Randy already wrote your machine is US model so all available drivers you should search on Toshiba US support page. Check it here .
