I upgraded mine to AC 1.10.90 RC 1.8.0 and had terrible range results. I was forced to downgrade RC to 1.6 and all is working like it should. Personally I wish I had never messed with it, if it is doing what you need and you're happy with the range.....leave it alone!! It is not easy to downgrade the AC once 1.10.90 is installed.
