Currently my deco m4R running on 2.4ghz of channels number 7,8,9,10,2  with 40 mhz width which does not reach satisfactory way and its range can reach only 20 feet throughout the wall brick and metal objects,  If i could select the channel number 1 or 6 or 11 with 20 mhz of width then it could reach the range that i expect. I'm disappointed now that what to do!!!  Great lesson for me buying this Bolsitttt paper weight.
