The hug5 is the 5Ghz radio and the hug2 is the 2.4Ghz radio. The 2.4Ghz band has better range, but can be affected by interference from other devices (cordless phones, microwaves, etc). The 5Ghz band has higher throughput (speed) and experiences less interference, but doesn't have the range that the 2.4Ghz band does. Some older devices, and even some less expensive ones today, can't utilize the 5Ghz band, but if a given device is seeing hug5 it should be able to use the 5Ghz band.
