A:Answer 5ghz is NOT necessarily better. It is faster, yes, because it has bigger bandwidth. But the speed is at the expense of distance. 5 GHz is faster but works best at shorter range, and starts dropping over a certain distance from the router/AP and is easily blocked by walls. 2.4Ghz is relatively slower than 5 GHz but can sustain signals over distance, easily twice that of the 5GHz, and penetrates thin walls. So "best" is relative depending on your set up requirements. And talking of "printing" which is almost like a UDP connection - you send across a few KBs or MBs of data over the network to the printer and that's basically it. There is no back and forth communication needing massive bandwidth. It's not like we are printing in the Terrabytes, in which case maybe a 5 Ghz connection really does come into play. I tried printing over wired Ethernet and at Wifi 2.4, and latency is negligible. The same comparison could be made between 2.4 and 5, given the amount of data to be transmitted to the printer.
