HP tests and posts many updated drivers from wireless adapter manufacturers. HP might have a more current version of the wireless driver than the one you are using. To find out if a driver is available for your model of computer, go to the HP software download site
and enter the model number to find software and drivers. In many cases, the wireless driver is part of a driver package for your motherboard called a chipset. When visiting HP's website, look for a wireless driver first, and then the chipset if a wireless adapter driver is not available. Read the details for the software downloads that are available if you need more information.
If your computer currently does not have access to the Internet, use another computer with Internet access to download and install the wireless driver softpaq to a USB storage device. You can then connect the storage device to a USB port on your computer and open the softpaq file that was downloaded to update your driver or chipset.
If the updated driver fails to solve the problem, go to the next step.
