Wireless network setup is typically a straightforward process, but problems do arise on occasion. If your wireless network installation isn't proceeding smoothly, try these troubleshooting steps to isolate the problem.
Check Your Owners' Manual for Wireless Network Setup Instructions
Manufacturers test wireless products before they ship them out, and they generally provide a list of the most common setup problems in the owners' manual to guide you through installation issues. Check the documentation, and see if any of the suggestions solve your problem. Some network devices, such as Linksys, are notoriously difficult to set up if you don't follow setup instructions precisely, so consider going back to the beginning and trying to set up the network again, following the setup instructions to the letter.
Power Down and Reboot
If your wireless network setup appears to be set up properly and the manufacturer's documentation doesn't have any helpful suggestions, try powering everything down and rebooting it. Unplug your modem and router and power down your computer, then power them up again, one by one. Start with your cable modem. Wait until all the lights are lit, indicating the modem is fully functional and has an active Internet connection. Then plug in and power up the router. Once the router lights indicate the router is fully functional, power up your computer. In many cases, this fixes network connection issues.
Check Cable Connections for Your Wireless Network Setup
People tend to overlook cables in a wireless network installation; however, some wired connections are essential, including your connection from your modem to the wall jack and the connection between the modem and the wireless router. Make sure that everything has power, and that no wires came loose during installation.
Look for Updated Drivers
Check your driver versions for your network adaptors and your router. Make sure your network interface controller, or NIC, has the most updated drivers, and that you're using the most recent version of your router's firmware. If you go into your Device Manager in Windows and your network adaptor has a yellow question mark on it, it's not fully functional. Follow Windows Help instructions to troubleshoot and fix it.
Consider Different Hardware for Your Wireless Network Setup
If you just can't get your wireless network to work, consider trying different hardware. Wireless router design varies from manufacturer to manufacturer. Linksys, for example, makes great wireless routers, but it can be very difficult to set them up with a DSL connection. Netgear is easy to configure for DSL. If you simply can't get your hardware to work after consulting the manufacturer's documentation and following troubleshooting steps, consider swapping it out with different hardware to see if it's easier for you to configure.
