Comments about D-Link D-Link Xtreme N DWA-556 PCI Express Desktop Adapter:
Under Linux it seemed to work OK, though I didn't test it extensively.
Barely usable under Windoze XP SP3; very weak signal and low thruput. So much for "... unrivaled wireless performance ..."
The latest drivers are completely broken; Windoze won't even boot with them installed.
The manager doesn't remember the password, forcing my family to re-enter it for every boot up.
My old (MSI) 802.11g PCI card in the next slot gets excellent signal strength, has about 4x the thruput, and just works.
