600 Mbps is a nice, fast Internet speed. With this, several devices would be able to stream simultaneously on this connection. To give specific numbers, we’ll refer to the FCC Broadband Speed Guide to see how many Mpbs are needed for average activities.
The R7000P Nighthawk with 10 devices connected simultaneously to its 5GHz radio could theoretically hit speeds of about 160 Mbps per device (1,625 divided by 10). As for the 2.4GHz radio at 600 Mbps, 10 devices connected simultaneously would drop theoretical speeds down to about 60 Mbps per device.
A good download speed is at least 25 Mbps, and a good upload speed is at least 3 Mbps. Some people can get away with fewer Mbps and others need more—but that’s a good internet speed for most people.
