Cisco Meraki MR66 vs MR76
The MR66 is an end-of-sale dual-radio 802.11n outdoor access point; the MR76 is its current Wi-Fi 6 (802.11ax) outdoor replacement. The MR76 roughly triples aggregate throughput, adds OFDMA and BLE, and keeps the rugged IP67 outdoor design, making it the standard migration target.

Choose Cisco Meraki MR66 if
Only keep the MR66 if it is already mounted in a low-demand outdoor location and a refresh is not yet budgeted. It still passes 802.11n traffic but gets no new features and is nearing end-of-support.
Choose Cisco Meraki MR76 if
Choose the MR76 for any new or refreshed outdoor deployment. Wi-Fi 6, OFDMA, dual-band concurrency, and BLE deliver far higher client density and throughput on the same rugged IP67 platform with external antennas.
Verdict
The MR76 is the clear outdoor upgrade. It keeps the rugged IP67 external-antenna design while moving from 802.11n to Wi-Fi 6, roughly tripling aggregate throughput and adding OFDMA, MU-MIMO, and BLE. With the MR66 end-of-sale and nearing end-of-support, plan the swap onto existing PoE+ drops and antennas where compatible.
Frequently asked questions
Is the Meraki MR66 discontinued?
Yes. The MR66 is end-of-sale and is progressing through Cisco Meraki's end-of-support lifecycle. It still works today but receives no new features and should be replaced.
What is the outdoor replacement for the Meraki MR66?
The MR76 is the current rugged outdoor Wi-Fi 6 replacement. It keeps the IP67 rating and external-antenna design while upgrading from 802.11n to 802.11ax.
Can the MR76 reuse my MR66 antennas?
Both are external-antenna outdoor APs, but connector and band coverage can differ between generations. Confirm antenna model compatibility before reuse; many sites pair the MR76 with current dual-band Meraki outdoor antennas.
Does the MR76 need different licensing than the MR66?
Yes. Meraki licensing is per device and per SKU, so each MR76 requires its own Enterprise or Advanced license; MR66 licenses do not transfer.
