I'm sure you see these threads all the time. However, I haven't found any threads that can help my situation.

I've restored my Toshiba Satellite C75D-B7304 to factory settings. Which took longer than usual, so I decided to shut it down and go to sleep for the night. That's when my problems began, but I've practically fixed all those issues, and now have Windows 8.1 as my new OS. Just thought I'd fill you guys in on how my previous Windows OS became corrupt.

Until now I've been using Ubuntu, but I felt lost without Windows, so I used a USB to burn an ISO onto, and reclaim my OS as Windows. Installation went smooth, no problems at all until I got to the desktop. It claimed I don't have any Network Connections, and I could only connect to the internet through an Ethernet Cable, which is weird since I've never encountered this before. Here's where I found out the reason as to why this was happening..

In the Device Manager, I found that under Other Devices, all of my drop down options were corrupt, and my drivers were missing. The only ones that are corrupt in all Device Manager are, Network Controller, PCI Device, PCI, Encryption/Decryption Controller, Unknown Device, and another Unknown Device.

I've tried to uninstall one and Update Driver Software under the action tab. Just installs the same corrupted... I don't know what to call it since it says it's missing a driver. To be precise, for all of them it says "The drivers for this device are not installed. (Code 28) There are no compatible drivers for this device." I've tried to update the driver but no luck.

Is there any way I can download the drivers on this computer, and burn them onto my USB then plug it into my computer and update it manually? If so, I don't know which drivers to install though I've been on Toshiba's website. Any help will be much appreciated, and I can post whatever info is needed to get this done, or fill in any information gaps you might need.

Also I'm very sorry if I made this thread in the wrong place, feel free to move it!
 
Caution: long answer follows.

Gotcha. A couple of questions. You say that you "now have Windows 8.1 as [your] new OS." What OS did it come with and factory restore to? The reason that I ask is that a factory restore should have left you with proper drivers for that version of the operating system! If it was still invalid directly after a factory restore, there may be other issues. And it's listed as coming with 8.1 64-bit.

Concentrate on getting the network working first. You wrote "It claimed I don't have any Network Connections, and I could only connect to the internet through an Ethernet Cable, which is weird since I've never encountered this before." Are you able to try it on an Ethernet connection? If so, does it work? This will make life simpler, since you could download drivers directly. Who knows, the automatic updates may work once you have a network connection.

If your machine won't connect to wired Ethernet but you are willing to try with the wired drivers, you will have to download drivers to another machine and burn them to USB (I hope that your USB ports are working), but once that works you can download the rest on that machine. I see three network drivers for Win 8.1 64-bit, one wired and two wireless. If you can wire your machine to the Internet, start with the "RealTek LAN Driver, Posted Date: 2016-01-19 | Version: 8.24.1218.2013 | Size: 7.95M." If that gets the network working, you can forego the USB stick from then on.

Next is the WiFi drivers. For some reason, they offer two different ones, Broadcom and Atheros. My assumption is that you can only use one. You can explore the Device Manager to see if you can determine which one is present. If you don't see either name, you can either try one after the other or use the technique that you will need for the Unknown Devices. Go into the Device Manager, open the Properties of the Unknown Device, and look at the Details. The easiest is the Device Description, but if it is there you probably won't see Unknown Device. Find the Hardware IDs. We can look it up online from the codes, and then determine the correct driver.

Let me know if this helps you make any progress, or if another approach is needed.
