FortiAP 431G tri-radio Wi-Fi 6E access point

The Fortinet FortiAP 431G is an enterprise-grade indoor wireless access point that operates across the 2.4 GHz, 5 GHz and 6 GHz bands. It contains three radios with four spatial streams each and includes two multi-gigabit Ethernet ports for wired backhaul. The unit ships with a standard mounting kit for ceiling, T-rail and wall installation.

Suits Wi-Fi 6E environments needing tri-band service

This access point fits networks that want simultaneous 2.4 GHz, 5 GHz and 6 GHz client access with 24/7 background scanning. It is not for buyers who require external antenna connectors, outdoor-rated enclosures or Power over Ethernet input beyond the 802.3bt standard supported by the two RJ45 ports.

Three radios deliver up to 4804 Mbps on the 6 GHz

The highest-rate radio reaches 4804 Mbps using four spatial streams on the 6 GHz band, while the other two radios provide up to 2402 Mbps and 1148 Mbps respectively. This combined throughput determines whether the AP matches the capacity plan for a given deployment.

Questions about this item

Will the FortiAP 431G work with my existing 802.11n and 802.11ac clients on the 2.4 GHz and 5 GHz bands?

Yes, the access point supports 802.11n and 802.11ac standards on its 2.4 GHz and 5 GHz radios, so older laptops and phones will connect normally while Wi-Fi 6E devices use the 6 GHz radio.

How can I verify the three radios are active after installation?

Log into the FortiGate or FortiCloud controller; the dashboard shows each radio — 2.4 GHz up to 1148 Mbps, 5 GHz up to 2402 Mbps, and 6 GHz up to 4804 Mbps — with client counts and channel status confirming operation.

Does the box include PoE injectors or a separate power adapter for the FAP-431G-A?

The package contains the access point with internal antennas and a standard mounting kit for ceiling, T-rail, and wall; power is delivered via the two 5 Gbps RJ45 ports using 802.3bt PoE, so no injector or adapter is included.
