I have a pretty basic ePMP setup with 1 AP and 2 SM’s less than a mile from AP. I’ve ran spectrum analysis on each device and It’s pretty clean. I even changed from 40Mhz channels to 20Mhz just to make sure I was not hitting anything even close to me. eDetect tool and logs report no problems. My problem may not be a problem but both SM’s seem to want to modulate at 50% MCS 1 and 50% MCS 15. I’ve noticed that when there is no real throughput usage then the radios will modulate at MCS 1 and when I start a download or something then I will see the packet usage on MCS 15 kick up. Is this normal? I’m getting fantastic throughput and overall am very impressed. However, when I was running 2.1 firmware I don’t ever remember seeing this -only when I added the second SM and updated firmware to 2.3. Anyone have any ideas?
