Hardware: Dell SX260, D-Link DWA-130 Rev B1. Router is D-Link DIR-655. OS: WinXP SP3 Connection is mostly up and down. The D-Link utility says it's connected, but Network Magic says it's not. Most of the time it cannot be pinged by other computers on my network. Windows says it has "limited connectivity". I've uninstalled and reinstalled the driver, with no effect. Moving the computer from its normal place in a room across the hall from the router to right beside the router does not help. On the D-Link website the only driver offered is only for Mac. Other computers on my network, both wired and wireless are fine. Rebooting the router does not help. I've been tinkering with this for several weeks, trying to get it to work consistently enough to be useful, but no joy, and I really don't want to run Cat5 across the hall. This DWA-130 was previously used on an IBM ThinkPad, in the same house, but a different room, and it worked fine. Any suggestions would be appreciated.
