range issue for digi s2b module

I am using UFL type S2B Pro module in 2.4GHz but not able to get the range more then 100 meter for LOS. I am using in Point to Multi point configuration. Which are the parameters will help me to get the more range.

Set the DL and DH of your coordinator to mach the SL and SH of your receiver. Also make sure that you have a good connection on your U.FL connection and that you have not bent over the center conductor.
