I cannot access wireless on my computer anymore. The section which used to say view wireless networks in the lower left of my computer is gone. I am able to connect to the internet via a wired connection, but cannot connect via a wireless connection. The computer cannot even view wireless networks in the area. The computer is a Gateway running XP
Suggests that there is a fault. Try deleting the entry from device manager and then press refresh (or restart Windows) it may request a driver so have any CD which came with the computer or wireless adapter handy or be prepared to search the hard drive for the driver -- probably to be found in the Windows, System32 folder.
