d86e64768859, an error in the edit results in the wrong firmware
being loaded for some models of the RTL8188/8192CE. In this condition,
the connection suffered from high ping latency, slow transfer rates,
 and required higher signal strengths to work at all

of the problems. This patch fixes all of those problems.
