A focused checklist to narrow a case where wireless clients reach the Internet but the PC’s wired LAN shows “connected” without browsing. This builds on points from and while adding concrete tests that identify whether the fault is physical, OS-level, or router/ISP-related.

Start with physical isolation: confirm the Ethernet link/activity LED on the PC NIC and on the router/switch port. Swap the cable and try a different router port (or connect a known-good laptop to the same port) to prove whether the port or cable is at fault. If the link LED is off, the problem is at layer 1 (cable, NIC, or port).

Gather IP info and try a lease refresh. On Windows run:

ipconfig /all
ipconfig /release
ipconfig /renew

On Linux:

ip addr
sudo dhclient -v <interface>

Look for the IPv4 address, subnet mask, default gateway and DNS. An address in 169.254.x.x means the PC did not get a valid lease.

Layered tests to pinpoint the failure: ping loopback, gateway, then a public IP and a name.

ping 127.0.0.1     (NIC stack ok)
ping <gateway IP>  (L2/L3 to router)
ping 8.8.8.8       (upstream routing/NAT)
nslookup google.com (DNS)
  • Loopback fail -> driver or NIC issue.
  • Gateway fail -> cable/port/switch/router link problem.
  • Gateway OK but 8.8.8.8 fail -> router or ISP upstream.
  • 8.8.8.8 OK but names fail -> DNS or proxy.

Other frequent causes: bad or outdated NIC driver, Windows power-management turning off the NIC, local firewall/proxy or antivirus blocking traffic, router features such as port isolation, VLANs, MAC filtering, or ISP MAC binding (MAC clone can be used from the router if binding is present). Useful diagnostics to post for follow-up: OS and version, router make/model, ipconfig /all (or ip addr), results of the ping steps, and whether the NIC link LEDs show activity.

So, if you use WiFi you can connect, but if you use a direct ethernet connection you cannot? If that is the case, then it is likely that you need to change your TCP/IP connection settings for the direct connection to use DHCP instead of a static IP address. If it has a static address configured, it may well not be in a subnet that your router is configured to handle.

Just clone the mac ip and your internet will be back on pc
