Choose Catalyst CW9164I if
Choose the CW9164I for general-purpose Wi-Fi 6E coverage where a 2x2 2.4 GHz radio and 2.5G uplink meet demand. It delivers full 4x4 performance on the 5 and 6 GHz bands at a lower price point.
Choose Catalyst CW9166I if
Choose the CW9166I for the busiest spaces where you want full 4x4 on all three bands and a 5G uplink to avoid wired bottlenecks under heavy 6 GHz load.
Verdict
Both APs deliver Wi-Fi 6E with 4x4 on the 5 and 6 GHz bands, so the CW9166I's advantages are its 4x4 2.4 GHz radio and 5G uplink for the highest-density areas. The CW9164I covers most Wi-Fi 6E deployments well; step up to the CW9166I where 2.4 GHz density and uplink headroom matter.
Frequently asked questions
What is the difference between the CW9164I and CW9166I?
The CW9166I has a 4x4 2.4 GHz radio and a 5G uplink, while the CW9164I uses a 2x2 2.4 GHz radio and a 2.5G uplink. Both are tri-band Wi-Fi 6E with 4x4 5 GHz and 6 GHz radios.
Are the CW9164I and CW9166I Meraki or Catalyst?
Both are Catalyst Wireless models that can be operated in Catalyst (controller) mode or Meraki cloud-dashboard mode, giving you flexibility on management.
Which Wi-Fi 6E AP has the faster uplink?
The CW9166I has a 5G multigigabit RJ45 uplink, versus a 2.5G uplink on the CW9164I, which matters when many 6 GHz clients drive high aggregate throughput.
What PoE do the CW9164I and CW9166I need?
Both draw up to 25W on 802.3at (PoE+) and up to 30.5W on 802.3bt (UPOE); 802.3af is not supported for full operation.
