Brand new build-ish. Old IDE HDD and SATA DVD-Writer, but everything else is brand new.
The Wireless Adapter came with x64 drivers (even said so on the box) hence why I bought it
And no, not had wireless working on it before. Attempting that now lol
Edit: Should say that the non-solid yet intermittent blinking green light on the PCI card indicates that it's not sending or receiving any data
Edit #2: Never mind, got my HomePlug working. Wooo. Now my brother will stop *****in'!
Edit #3: Well, it works, but it's quite slow. Although it says 100Mbps wired network connection, it only appears to let roughly 15KB/s to be transferred via the homeplug network, and that's just with the PC on on it's own. I'll post the Settings for the network adapter on here soon
