usb 3.0 and wifi problem

For problem 1, try doing a system restore. You might have installed some software recently that has replaced an important file needed to recognize and run your hardware device. (USB 3.0) Doing a system restore will not delete any personal files like music or videos. Perhaps a few programs though. System restore will tell you what installed progam software you will lose before proceeding so there's no need to worry about unexpected important files suddenly going missing. 

Another solution is to check if your hardware is running properly for your USB 3.0 device by going to your device manager. You can find the device manager by searching in "settings" after moving your mouse all the way on the right side of the screen and clicking the search function.

For problem 2, you might have a bad driver. Test for problems on the Network and sharing center by clicking on "troubleshhoot problems" below the dialog box. If a bad driver is confirmed, search for "Network and sharing center" and then go to "Change adaptor settings" to see what the name of your network brand chipset is. Then search online for the offical site for a different driver version to try. Also try unchecking the "turn off this device when possible to save power" option in your network adaptor settings.

Another possible cause is interference by a cell phone close to your PC. Remove any cell phones or other similar moble devices farther away from your PC. 

Hello, for your wifi problem, try checking if a service called Wlansvc (Wlan Auto config) in the services tab of the task Manager is running or not. If not, right-click the service and select "start". If it's already running, restart the service. See if that helps.

My USB 3.0 driver is the AMD USB Extensible host controller - 001 Microsoft. Do you perhaps have a simular controller name starting with your processor name exp: AMD, Intel? Click on the resourses tab while viewing the drivers properties in the device manager and check to see below if any conflicts are present which could be causing your USB 3.0 device to run incorrectly. 

Also when inserting any cables or especially hard plastic casing like thumb drives into your Usb 3.0 port, make sure that you insert your device quickly instead of slowly because if done too slowly your computer will load your device as usb 2.0 opperation instead.
