I have my Mac in a very close separate building, facing the router through glass. I have an extender for the 2.4 band. When I connect to the 2.4 band I get an "excellent" in performance in wireless diagnostics, with RSSI around -49 and transmit rate of around 115. My Ookla speed test runs around 27 Mbps down and 13 up. On the 5.0 band I get a "poor" performance with RSSI of -84, transmit rate of 54.....but the download speeds on Ookla average around 35 to 40 down and 11 to 14 up. In other words, the 5.0 band looks like it has worse RSSI and transmit rate numbers, but it has generally higher download and upload speeds. I realize the 5.0 has baseline higher speeds, which apparently offset the lower transmit rate...I guess. With this option, which band would you select?
