... you may just be throwing $11 plus shipping and hours of your time down a rat hole. I bought a "retail box" version of this adapter from Amazon last week for about $20. After installing it in my IBM Thinkpad laptop, I found that the laptop would no longer go into standby (sleep) with the adapter present. Further on-line investigation suggests that the Linksys driver does not properly implement Microsoft's NDIS driver standard in the area of device power control, and hence blocks the standby operation.Linksys' driver for the device I bought (WRT54G, v3) was last updated over two years ago, although a search shows that numerous other purchasers of this device been have complained about this problem, as well as the ineffectiveness of Linksys customer service. As a retired Cisco exec, I am truly ashamed of the shoddy quality of this device software.
