Could it be that the driver for my wireless card is kind-of but not totally compatible with windows 8? I have a DW1520 Wireless-N WLAN Half-Mini Card and its latest driver is Windows 7 64 bit compatible. When the windows 8 compatible driver becomes available will it automatically download? Does anyone know? For now I'll download and stream using my old system.
Hey Man, I have Dell XPS M1330 with DW1505 Wireless card, had the same issue since installing Windows 8 two days ago.
Found the solution right now.
download this driver from Dell's Website: dell.com/support/drivers/us/en/19/DriverDetails?driverId=R295615
its some kind of all in one driver for our cards. go to device manager and update the driver select to search manually and not automatic and click have disc, navigate to where you extracted the driver and select from the drivers folder the Win7 folder and then WL folder, and install the driver available there.
Worked for me perfect, now wireless is speedy just like ethernet
