Just thought I'd chime in after reading what c0rr0sive said in regards to wires near your wireless. I have a similar setup with router downstairs and laptop\desktop upstairs. I had to relocate my tv to the other side of the room to fix similar issues with wireless. Also I thought I would mention this as well. D-link DWL-G820 I bought this as opposed to a pci type wireless card and I couldn't be happier. Its fast and has a strong signal.
