Product Description
The Datto AP840 is an indoor, cloud managed WiFi 6 (802.11ax) access point built for spaces with lots of devices online at once — think small offices or busy commercial premises rather than a single home router replacement.
WiFi 6 (the "802.11ax" jargon) means better handling of many simultaneous connections, not just a top-line speed boost. That matters if you've got dozens of laptops, phones and IoT devices fighting for airtime.
Key specs
- Dual band: 2.4 GHz and 5 GHz simultaneously
- 4x4 MU-MIMO with OFDMA: lets the AP talk to multiple clients at once instead of queuing them
- Combined throughput: up to 3.6 Gbps (1148 Mbps on 2.4 GHz, up to 2400 Mbps on 5 GHz)
- Recommended user load: up to 250 concurrent users
- Wired ports: one 2.5 Gbps multi-gigabit Ethernet port plus one Gigabit Ethernet port
- Power: PoE 802.3at (48V DC) — one cable for data and power
- Extras: integrated BLE and a dedicated scanning radio for wireless monitoring
Before buying, check your switch can actually deliver 802.3at PoE, since this AP doesn't ship with its own power adapter mentioned in specs — it expects PoE from your network gear. It's designed to mount on ceilings, walls or T-rail structures, with an installation kit included, and management (firmware updates, monitoring, roaming, mesh, captive portal) is handled through Datto's cloud platform.
