Windows 10: Cannot connect to wifi

Hello, I'm running a Surface Pro 3. I use it for work and my personal life. At work, we have three different wifi connections. My preferred one is the "guest" wifi. I've been using it since I got my Surface almost 2 years ago. I've never had an issue. Two days ago, I noticed I wasn't connected to the web. I disconnected and reconnected to the guest wifi. It showed "No Internet, secured". Chrome shows that the DNS address could not be found. I am able to connect to the other two wifi options and access the web (I prefer the guest access because it doesn't limit what I do on the web). I took the surface home with me and again, no issues connecting to the wifi at home, or some public wifi I tired. Everyone I've talked to is able to connect to the guest wifi at work without issue. My network administrator (who is technically not allowed to work on my surface because it is not a company device) says nothing has changed on his end.
I followed some of the trouble shooting steps on other posts. I did run the system file checker and determined that opencl.dll (I think that is the file name) was damaged. I was unable to repair it.
I am hoping someone could possibly run me through troubleshooting this issue? It's an annoyance more than anything and I would like to see if I can fix it. Thanks in advance.

Internet sharing issues in Lumia 730

is your 730 connected to wifi, or is it connected to the cellular network?

if you are already connected to wifi, you cannot share that wifi connection, you have to be on the cellular network.

 

How do you connect Lumia 635 phone to a WIN 10 PC, via WiFi?

You cannot natively connect a PC to a Windows Phone over wifi except to tether, i.e. use the phone's mobile data connection from the PC over a wifi connection ("Internet Sharing").

You cannot see it or add it as a "connected" device, access or move files or do anything at all over wifi.
