Hi, I was struggling with the same. My MX was connected to a LAN port sitting behind my ISP router. My colleague shared a setting that resolved this issue for my setup.

Well thank you both for the reply. The question was fairly straightforward asking for the default setting. And the answer was also straightforward. The underlaying reason of my question is of course more complex. The issue i'm seeing in one of the many office locations is that even with the minimum power set to 5 - the Meraki Access Points still hear each-other very 'loud' (-54 to -62dBm) on the same channel. And all most all of them dropped transmit power to 5. Even with the Radio Channel set to Auto, I get up to 5 Meraki AP's on the same channel.  They keep changing channels - over and over again, but only choose the lower range UNII-1 channel range. They do not use the other channel ranges although they are available.   For now, only one office location is showing this, and we have a felling this started after MR 28.7 - September 10th. Anyhow, I have a ticket open with Meraki support on this issue. I will follow up when I have some news.   Thanks JohnDH ... View more
