The ACM5504-5-G-W-I and all IM7200 models have an internal 802.11 adapter that can be configured as a Wi-Fi WAP (Wireless Access Point) or as a Wi-Fi client.
All the IM7200 models and the ACM5504-5-G-W-I model have an internal 802.11 WiFi adapter and are supplied with an external WiFi antenna. The WiFi can be configured as a Wi-Fi Wireless Access Point (WAP) or as a Wi-Fi client. This inbuilt WiFi facility is inactive by default. To use the WiFi facility you will first need to attach the WiFi antenna.
Before powering on the unit:
- For IM7200, screw wireless antenna on to the WIFI (MAIN) SMA connector. The IM7200 has a second WIFI (AUX) connector for diversity. Requires an external antenna (part # 569022)
For ACM5504-5-G-W-I screw wireless antenna on to the main WIFI (M) connector. The ACM5504-5-G(V)-W-I has a second WIFI (A) connector can be used for diversity and requires an external antenna (part # 569011)
To activate and configure the WAP functionality:
- Select the Wireless Network Interface tab on System: IP and un-tick the Disable box
- Configure the IP Settings for the Wireless Network. Generally, if the device is being used as a Wireless AP, a static address is set here in the IP Settings. In this example, 192.168.10.1 is used. Set the IP address, and the netmask (in this case, 255.255.255.0 to give 254 unique network addresses in subnet), but do not fill in the Gateway, Primary DNS and Secondary DNS. These settings are used if the interface is to be the primary network link to the outside world, or if it will be used for failover.
- Select Wireless AP, which will make the Wireless AP Settings section visible:
Country: Select the correct country from the list. If the country does not appear, select the World Regulatory Domain
SSID: Select an SSID for the network. It should be unique.
Broadcast SSID: Tick this to broadcast the SSID. This should generally done, disabling broadcast is not a security measure
Network Channel: Select the network channel. 6 is most commonly used, so it is best to do a site survey and pick another channel if the unit is being deployed into an office environment
Hardware Mode: The unit supports 802.11b,g and single band 802.11n. In most cases, selection 802.11b/g/n will provide for the best interoperability with other hardware.
Supported Authentication Methods: Select the authentication method for the AP. If the client equipment supports it, it is always best to selecte WPA/WPA2 and AES encryption. WEP and WPA with TKIP have been proven vulnerable to cryptanalysis.
If WEP is selected:
WEP Mode: Select Open System or Shared System. Open System is more secure than Shared, due to the way encryption keys are used.
WEP Key Length: Select the WEP key length. 128 bit keys offer more security, but are not supported on all devices. WEP Keys must be entered in Hexidecimal.
WEP Key 1-4: Up to 4 WEP keys can be used on a single network.
Default Transmit Key: This selects the default transmit key for the network
If WPA/WPA2 is selected:
WPA/WPA2 Encryption Methods: Select one or both of TKIP or AES for encrypting WPA/WPA2 connections. AES is more secure, and is required for the AP to advertise itself as 802.11n if that hardware mode is selected
WPA Password: The password that clients will use to connect to the AP.
- Once the Wireless AP Settings have been filled out, click Apply, then wait for the page to refresh.
- The next step is to set up a DHCP server for the wireless clients. Click the link next to DHCP Server in the IP settings section, or go to System: DHCP Server page. More information on configuring DHCP can be found in Chapter 3.6.2
Note The Wireless screen on the Status: Statistics page shows the list of clients that are connected to the WAP
