2.4ghz Weather Station not able to link with xFI router.

I tried to hook up my 2.4mhz weather station to my xfinity router and kept getting a message that I had to get away from the router with my phone to get it into a 2.4ghz connection. I tried doing that but then my phone is too far away from the weather station to link the router information. I tried separating the signals but that didn't seem to help. I also tried disabling the 5ghz signal and again it didn't help. Please help!
