I have a Dell Vostro 5470, Windows 8.1, 64-bit. Yesterday my internet connections simply stopped working: my laptop won't connect to any wifi network (although it sees them) and the ethernet connection is always limited. I've tried multiple networks. I am on an university network and nobody else is having problems. I have already updated my drivers.
Thank you very much for any help you might give me.

I have seen malware unable "Proxy Server". Look at "Connections" in Internet Options. If Proxy Server is checked, un-check it. Then run your anti-malware software, I use Malwarebytes.

Internet connectivity problems can occur for a variety of reasons to include corrupted networking software installation, third-party software inserting itself into the network adapter settings, misconfiguration or corruption issues with TCP/IP protocol stack and Winsock due to malformed LSP, deletion or incorrect removal of networking software and removal of a malware component which had inserted itself into the winsock. There are some common (but simple) solutions which can help resolve connectivity issues...refer to these instructions.
