Laptop Wireless Problems: Common Cause And Solutions

Laptop wireless problems are fairly commonplace occurrences in this day and age, although that certainly does not make them any less frustrating. It also doesn’t help matters any that different manufacturers have slightly different ways of implementing laptop wireless systems, although there are obviously a few key factors that remain constant.

All laptop wireless connections are dependent on RF signals for both receiving and transmitting signals. When you start up your laptop and see a cross mark on the network icon on the taskbar, that is usually the first sign that there is a laptop wireless problem on your hands. If that is the case, you will have to troubleshoot your wireless connection, first checking to make sure that the wireless network adapter is drawing power. Keep in mind that come laptops will have either a red or blue button on the side, which enables the wireless adapter. You will also have to make sure that you are using the correct drivers for your wireless laptop adaptor.

Below are some steps on troubleshooting your laptop wireless problem:

1. Check the physical connections to and from your laptop.
2. Make sure that your wireless adaptor is installed and working.
3. Check to make sure that your LAN settings are correct.
4. Check the TCP/IP settings of your client.
5. When you do have a valid IP address, “ping” the address to verify your connection.
6. If you still can’t connect to your client look into possible problems with your wireless adapter.
7. If your wireless client and router can communicate with each other but cannot exchange data, the possible cause may be a security setting.
8. Make sure that RADIUS is working as normal.
9. If RADIUS does work, but access requests from your client are rejected, look you may have an authentication protocol or login problem.
10. Finally, if you are able to connect and ping your client successfully, but experience an occasional or random laptop wireless problem, look into factors such as poor signal, interference, or AP roaming disconnection.
