While investigating WLAN issues and enjoying the new capabilites of the dashboard I noticed something. "Terrible data rates!!!" I thought at first but upon closer inspection this seems like a miscalculation. Clicking the info-button shows: "This graph shows data rates used as a percentage of the maximum data rate that this client supports." So if my device supports 80 MHz channels and can do 2 spatial streams it's max data rate is 867 Mbps. The client info in the dashboard confirms this BUT if I'm using 20 MHz channels on this AP (which I should, and am), the maximum data rate for this client is 173 Mbps. Looking at the statistics from the client: 18% of 867 Mbps is 156 Mbps. That would be the second best data rate for a 2SS client on a 20 MHz channel. Shouldn't the chart show 90% instead of 18% if the data rate is 156 out of 173 Mbps?
