But how am I supposed to run the file if I can't open the webpage to get here to click on the link lol? I'm using my phone on this forum right now.
Most of us would use another machine to download the file then put it on a USB stick so as to move it onto the machine with a problem.
In your case you can try running the following two commands, run them one at a time either typed or pasted into an elevated command prompt, hit enter after each one then reboot the machine.
No guarantee's here as I haven't even looked at the ipconfig/all from this machine yet, so I'm really just guessing at what the problem might be from your explanation of the problem.
netsh winsock reset catalog (reset winsock entries)
netsh int ip reset reset.log hit (reset TCP/IP stack)
