Thanks for the reply. Good advice from both you and Chris. I actually am just using the plain jane wireless adapter that walmart had put in this old HP Pavilion ze4900. As a general rule it does fairly well, but not so well that it would out-perform the PCI cards I use. I figure if the laptop will connect, the PCI card will definitely work, usually a lot better. Unless... something happens like what did yesterday.
Sure wish I knew what was happening. The recommendation for wi-spy is appreciated. John Mark Williams wrote: > I have seen this before also.
