Building on the thread contributions from and , here is a short, practical troubleshooting sequence to isolate whether the fault is the PC, the NIC/driver, the cable/port, or the router/DHCP. The steps are ordered from least invasive to most, and include commands and quick checks that are useful to record when diagnosing.

  1. Quick isolation
  • Try the same Ethernet cable and router port with a different PC or laptop. Try a different cable and a different port on the router/switch. A working device on the same cable/port proves the router/cable are OK.
  1. Windows and driver checks
  • Look in Device Manager for the Ethernet adapter (Network adapters). If an adapter is missing, flagged with an error, or listed as "Unknown device", obtain the correct driver from the motherboard/NIC vendor on another machine and install it from USB.
  • Confirm the NIC is enabled in BIOS/UEFI if it is onboard.
  1. Basic network diagnostics (run at a command prompt)
  • Collect these outputs for diagnosis:
ipconfig /all
ipconfig /release
ipconfig /renew
ping 192.168.1.1
ping 8.8.8.8
  • A 169.254.x.x address indicates no DHCP lease. Trying a manual static IP (example: 192.168.1.50 / 255.255.255.0 gateway 192.168.1.1) can show whether link-level connectivity to the router exists.
  1. Other useful checks and cautions
  • Disable the wireless adapter to force Windows to use wired during testing. Check adapter speed/duplex and set to Auto if mis-matches occur.
  • Booting a live USB Linux distribution can confirm whether the NIC and cable work outside of Windows.
  • Resetting the router restores defaults but will remove ISP/PPPoE credentials and custom settings; note credentials before a factory reset.

Summary checklist: verify cable/port with another device, confirm NIC presence and drivers in Device Manager, capture ipconfig /all and ping results, test with a live USB or alternate NIC if needed, and only reset the router after backing up or noting ISP settings.

Do you know if your network card is working?

Go to network connections and see if the wired one is there?

Also does it show that it is connected on the router? Should be a light on for something like Lan 1 or 1.

it has the light lit yet, also network connections show my wireless one and 1394 connection only

Does the wire connection display as connected/enabled/disabled?

Can you acces your router via the PC using the router IP address?

Are you sure it isn't blank or user Admin password admin. The password and user maybe on the back of the router.

You can reset the router to it's factory settings to regain access.

However it doesn't prove you connections are working.

Is your internet connection via ethernet?

Ethernet is what will be connected between your computer and the router.
