A Few Thoughts:

A. Disable Wi-Fi (Or Try Wi-Fi only):

See if it now connects. Also, be certain your are connected to the correct SSID (Network Name).

B. Use MalwareBytes for Mac:

This is software that searches for malware/adware. So, scan with it and then remove what is found. Once removed, uninstall MalwareBytes for Mac. Then restart the Mac. It is created by longtime users of these forums. So, that is why it is the only way to go about securing your Mac, when it comes through use of software 

Downloads:

1. Malwarebytes Anti-Malware for Mac
2. Malwarebytes uninstaller

C. Create a Third Admin User:

What happens when you create a new Administrator User? You would transfer everything over to it from this user, and then delete this current user.

System Preference > Network > Ethernet|Wi-Fi ....

what does that screen say?

If you click on the Hardware tab there, is it showing a Proxy? if so, remove it.

To be used, Ethernet must be the TopMost, Working inteface and must have a cable plugged in. If not TopMost, use the gear icon below the left box to "set Service Order" and move Ethernet to the Top.

Please post a screenshot of the Ethernet pane.

Your SYMPTOMS, please, not your conclusions.

so you have an IP address showing on that page, and you can enter web site names and get their splash pages? can you make secure connections (little lock to the left of the website name)?
