Most likely cause: network connectivity (IP and gateway) is fine but name resolution is broken. The ipconfig output posted by shows the DNS server entry appears corrupted (two addresses run together). When the DNS field is invalid, browsers and most programs can no longer resolve hostnames even though the machine still has an IP and a gateway — that matches the symptom “connected but nothing works.”

Quick, non-destructive checks to confirm DNS failure:

ping <default-gateway>
ping 8.8.8.8
nslookup www.google.com

If ping to the gateway and to 8.8.8.8 succeed but nslookup fails or reports no server, the problem is DNS-only.

Practical repair steps (safe, ordered):

  • In Network Connections -> adapter -> Properties -> Internet Protocol Version 4 (TCP/IPv4) -> Properties, set DNS to "Obtain DNS server address automatically" or manually enter a known-good pair (example: 8.8.8.8 and 8.8.4.4 or 1.1.1.1 and 1.0.0.1).
  • Flush and reset local stacks, then reboot:
    ipconfig /flushdns
    netsh winsock reset
    netsh int ip reset resetlog.txt
  • Reboot and re-test with nslookup and a browser.

If the DNS field can’t be fixed or the corruption returns, check recent installs (the issue appeared after a McAfee attempt). Consider uninstalling that security suite fully (use the vendor removal tool or System Restore to a point before the install), scan for malware in Safe Mode with Networking, and verify the router’s DNS settings as well. See ’s linked thread for a similar case and adapter-reset suggestions. Back up any custom network settings before making changes.
