Hosting the Network: Limited to Gateway Mode
Given the above, it seems likely that the Express 7 can host the UniFi network, meaning run the controller software, only when in gateway mode. This mode enables it to provide the necessary network services for management, such as DHCP, routing, and firewall functions, which are essential for the controller to operate effectively. In contrast, AP mode positions it as a subordinate device, managed by another controller, and thus unable to host the network.
This conclusion is reinforced by the device's design, marketed as a "Cloud Gateway" first, with AP functionality as an additional, secondary role for network expansion. For example, the NasCompares review from February 25, 2025, emphasizes its primary role as a network gateway, recommending it for scenarios where gateway services are needed (

Comparative Analysis with Other UniFi Devices
To provide context, other UniFi devices like the Dream Machine or Cloud Key are explicitly designed to run the controller, often in gateway configurations. The Express 7's ability to run the controller aligns with these, but its mode-dependent functionality (gateway for hosting, AP for extension) is a notable feature. This flexibility is unexpected for a compact device, offering users the option to scale from a standalone network to part of a larger system, but it requires understanding the mode implications for hosting capabilities.
Table: Operational Modes and Hosting Capabilities
| Mode | Role | Can Host UniFi Network? | Key Features |
|---|
| Gateway Mode | Router, Network Hub | Yes | Runs controller, manages other devices, provides routing |
| AP Mode | Wireless Access Point, Extension | No | Managed by another controller, extends WiFi coverage |
This table summarizes the modes, their roles, and whether they support hosting the UniFi network, clarifying the dependency on gateway mode for management functions.
User Implications and Recommendations
For users, this means that if you want the Express 7 to host your UniFi network, configure it in gateway mode, ensuring it acts as the central management point. If you need additional WiFi coverage and already have a controller (e.g., another UniFi device), you can set it to AP mode, but it will not host the network. This dual functionality is particularly useful for small to medium networks looking to scale, offering cost-effective solutions without needing separate controller hardware initially.
