Can't Log Into Router (any Browser). G3100

[Agrajag]

On my desktop (Windows 10) I cannot log into my router no matter what I try: Chrome, Firefox, Edge, IE, Incognito, cleared cache, cookies and history. On my phone and laptop I can log in.

On the desktop if I go to either myfiosgateway.com or 192.168.1.1 I get to the login screen but it's a dead screen. Clicking Show Password doesn't show the password. I can enter the password, but clicking the Sign In button does nothing. It highlights the button, but that's it.

Any ideas?
