The ENH500 can be configured via Telnet using its command line interface or via web-based menu. The menu appears nearly identical to the ENS200's. Configuration options are listed in a simple menu along the left side of the screen, as shown below.
Configuration on the ENH500 via the web-based menu can be a bit slow as I noted on the ENS200. You make changes and click Apply, then click Save/Load for the new settings to become active. In the meantime, you get to stare at the screen below for up to one minute before you can perform further configuration.
A new tool for managing the ENH500 is EnGenius' EZ Controller Widows-based software (screenshot below), which is a free download from the EnGenius website. The EZ Controller software provides a central tool for managing multiple EnGenius devices. This software allows you to configure multiple devices simultaneously, view traffic, upgrade firmware, upload floor plan maps, and view various realtime statistics.
As with the ENS200, I found the manual a little sparse in details and examples. However, if you poke around EnGenius' website, you can find additional useful support information.
The ENH500 has multiple operating modes. Traditional operating modes are Access Point, Client Bridge (default), and Client Router. There is also WDS mode with three sub-modes. I'll describe WDS mode in the next section.
As an Access Point, the best use for the ENH500 is to direct its wireless signal at another ENH500 configured in Client Bridge or Client Router mode. The ENH500 is limited as an Access Point for end device connectivity, as only end devices that support 5 GHz will be able to connect to it. Further, the ENH500 has a directional antenna, so it will provide a narrow coverage area.
As an Access Point, the ENH500 can broadcast an 802.11a, 802.11n, or 802.11a/n signal with 20, 40 or 20/40 MHz channel bandwidth. A screenshot showing ENH500 Access Point wireless configuration options is below.
In Access Point mode, up to four SSIDs can be enabled on four different VLANs. Security options are WEP, WPA, WPA2; TKIP and AES encryption and 802.1x authentication via RADIUS server.
In either Client mode, the ENH500 can pick up an SSID broadcast by another Access Point and connect it to a wired LAN. If the ENH500 is in Client Bridge mode, devices connected to the Ethernet port of the ENH500 will get an IP address from upstream network. If the ENH500 is in Client Router mode, the ENH500 will function as a gateway router with NAT, so that devices connected to the Ethernet port of the ENH500 will get an IP address from the ENH500.
To connect an ENH500 in Client mode to another Access Point, there is a useful Site Survey option to scan for available SSIDs. The Site Survey tool can also be used in other modes to detect nearby wireless networks and fine tune channel selection. Once the scan is complete, simply click on the desired network and add the necessary security parameters to complete the connection.
In the screenshot below, you can see the ENH500 is in Client Bridge mode and is connected to an SSID called MDC10, a Ubiquiti Access Point.
Advanced wireless options on the ENH500 are the same as the ENS200. Those options include settings for data rate, transmit power, RTS/CTS thresholds, distance, and frame aggregation. Finally, wireless traffic controls exist for traffic shaping and setting incoming/outgoing traffic limits.
