Most home routers have a gateway address that starts with 192.168, like the address shown above. The Default Gateway is the address of your router. Output similar to the following example should appear.Ĭonnection-specific DNS Suffix. At the command prompt, type ipconfig and press Enter.Linux users can substitute ipconfig for ifconfig.
Below are the steps for Microsoft Windows users. Using the ipconfig command (or ifconfig command for Linux), determine the router's address by looking at the Gateway address. If your network has a router, make sure the computer is connecting to the router with the following commands. If the network card is defective, it needs to be replaced.
Check the network card manufacturer's website for the latest drivers and install those drivers. Make sure the network card is physically installed in the computer correctly by removing it and re-inserting it again. If you get an error, or the transmission fails, the network card is not connected correctly, has the incorrect or outdated drivers installed, or is defective. To ping the card or the localhost, type either of the following commands: ping 127.0.0.1Įxecuting either of the above commands should get replies from the network card. Unix and Linux users can ping from the shell. Windows users can ping the computer from a Windows command line. Verify the network card is capable of pinging itself using the ping command.
If the incorrect password is entered, you won't be able to access the network.
If the button is turned on, make sure you're using the correct Wi-Fi hotspot by right-clicking the Network icon in the Windows Notification Area and clicking "Connect to a network." Usually, the network with the strongest connection (the most bars) is your wireless router.įinally, when connecting to most wireless networks, you need to enter the proper SSID password to connect to the network. The pictures are examples of a Wi-Fi button and Wi-Fi indicator on an F key that are enabled. The Wi-Fi button may be above the keyboard, on the front edge of the laptop, or integrated with an F key. Many laptops have a Wi-Fi button that allows the wireless network to be turned on and off. If you're using a laptop with a wireless network, look for the laptop's Wi-Fi button and make sure it is turned on. If, after checking the connections, the LED indicators appear bad, the network adapter, port, or cable may be defective. If you're on a small network and can check the hub, switch, or router, verify the cables are connected correctly, and it has power. If there are no lights or they're orange or red, the card may be bad, not connected properly, or may not be receiving a signal from the network. With this port, one LED lights up if connected properly, and one flashes when transmitting data. The picture is an example of a LAN port with two LED indicators next to the RJ-45 port. If the green light is flashing, this is an indication of data is transmitting. For example, a desktop computer network card with a solid green LED or light usually indicates that the card is either connected or receiving a signal. If this is a wired network, verify the network cable is connected correctly and make sure the LEDs next to the network jack are properly illuminated.
How to remove a device in Windows Device Manager.
If Windows re-detects the card but does not find the drivers, download the latest network card drivers from the computer manufacturer's website or the network card manufacturer's website. Try letting Windows re-detect and install the network card by removing the network adapter and any other conflict devices from Device Manager and then rebooting the computer. If conflicts exist or the network adapter is detected as an "Other device," the network card is not installed correctly.
