Query: Useless

I bought this based on the positive reviews here, but I was never able to get a signal of more than 30% and it often dropped the signal down to a level that was unusable. I almost never got more than 5.5Mbps. I am only about 50ft from the router. I bought a new card from MSI (for about the same money) and I have nearly 100% signal with a consistent 54Mbps.
