Plug an Ethernet cable into this computer

These are some suggestions for restoring your wireless connection in Windows 7.

1. If you are using a router, push the reset button on the router to toggle it off, then wait 10 seconds and push the reset button on the router again to toggle it back on.
2. Try uninstalling the wireless driver and reinstalling the driver and reboot your computer.

Ethernet is a family of computer networking technologies for local area (LAN) and larger networks. An ethernet cable looks like a telephone cable, but the connector is wider. A telephone cable has 4 pins, but an ethernet cable has 8.

If your laptop has an ethernet port, then plug in an ethernet cable to make a wired connection from your modem or router to your laptop. The ethernet cable connector will make a soft clicking noise when the plastic spring engages in the ethernet port, indicating that the ethernet cable is firmly plugged in to the ethernet socket as it should be to have a proper electrical connection.
