Just found out the eero cannot separate the frequencies. So how do I take advantage of the higher speeds available on 5 G.
Your device should go to the best one. On some devices, you can force which frequency to use (a lot of phones let you pick, for example).
But, as you said, the eero broadcasts the same SSID for both frequency bands. You can't use different names.
We're big on support, and we want to make sure you always have the best eero experience possible. Here are several resources you can use if you ever need our help!
