"Belkin was displaying its Gigabit Powerline HD Starter Kit...."
Does this have that wonderfully innovative Belch-kin mis-feature where the device will hijack your connection randomly to show you ads for other Belch-kin products?
Seriously - I would NEVER put Belkin gear any place where it could theoretically modify the communications. Add to that Bletch-kin gear is usually overpriced for what it is....
What did you purchase that was giving ads? I have never had this problem with any Belkin networking devices and they have always worked well. **shrugs** Besides Gig-E over power sounds promising if actually works.
Is your job running? You'd better go catch it!
