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.

One of the most commonly seen HP Pavilion laptop problems have to do with the wireless feature. It became increasingly–and alarmingly–clear that more and more users were experiencing HP Pavilion laptop problems that had to do with the WiFi capability failing. It wasn’t long before the support forums were flooded with complaints about such HP Pavilion laptop problems.

After long weeks of silence, the company eventually admitted to HP Pavilion laptop problems particularly with regard to the WiFi capability. To address the issue, the company posted BIOS settings that were intended to solve these problems. Unfortunately, not only did this “solution” not make things any better for most users, it in fact caused quite a few damaged motherboards that required a costly replacement. It was apparent that these particular HP Pavilion laptop problems were rooted in hardware and could not be addressed simply by updating the BIOS.

While these reports are admittedly based on other people’s experiences with HP Pavilion laptop problems, there are enough reports floating around on the Internet to indicate that there may in fact be something wrong with this line. Even HP’s own site is filled with user complaints about this very issue, so one would hope that the company is taking steps to rectify the problem. The silver lining in all this is that HP is generally very good about replacing hardware when necessary, so if your machine is still under warranty, you should be able to find a solution that will meet with your approval. And for those who’s units have lapsed warranties, the sad truth is that you may have to shell out for a new one.

Keep in mind that some laptops will have small buttons on the side to turn them on, while others will have to be enabled by way of the operating system.

For Windows machines, the first step in troubleshooting a laptop wireless problem is going to Device Manager and checking whether or not the network adapter is enabled. If it is disabled, it is a simple matter to click on the option to enable it. If your laptop uses a PCMIA or USB wireless adapter, you may have to remove it and insert it again. You should be able to tell at this point if the laptop wireless problem is fixed by the lights on the adapter.

Another thing you should check for is driver compatibility, making sure that the correct device driver is installed for your particular wireless Internet adapter. Without this driver installed, you may well run into all sorts of laptop wireless problems. Make sure also that you have installed the router properly, with a 5v driver instead of the 3v driver.

In some cases, a laptop wireless problem may simply be the result of a low signal from your wireless network. If that is the case, the problem can be solved by making sure that any cordless phones, microwaves, and other electrical equipments are placed 1m or more away from your access point. It may also be helpful to change the channels on your access point.

These tips will have hopefully clued you in to some of the more common causes of a laptop wireless problem and helped you find a solution to them. Even if you have tried them and failed to find a solution, you will at least have a better knowledge of how your laptop wireless systems work.
