1.4 Network Configuration Local Network External Network Gateway Internet WiMAX PC To Verify normal operation of router LEDs You have to check if each LED of the router operates properly after connecting router, modem, and PC with LAN cable as follows:.
If LED light is not in “normal operation”, check if there is any failure according to actions to be taken. Install a router after connecting to network. „ If normal connection between router and PC is checked, you have to set up PC and router. Router setup is to connect a router to Internet, which is suitable for the Internet line type that is connected to router. It is progressed by referring to Chapter II, depending on Internet type.

2. A Simple WiMAX gateway Implementation Included in the software development package is the sample WiMAX gateway implementation. The target system has a WiMAX interface at one end and a Ethernet interface at the other end. The embedded connection manager automatically makes a connection to the WiMAX network whenever it detects one. The IP layer is configured to perform NAT so that the host in the inner (private) network can connect to internet via external WiMAX network.
[DM command] d ver wb_ru keeps showing log messages from the WiMAX MAC. The user can switch it to “interactive mode” by typing in ‘q’ in the console. During interactive mode, all the MAC messages are temporarily suppressed and the connection manager shows the prompt “DM>” for the user to enter commands. The user can also switch back to “monitoring mode” by simply entering “Enter” key. 2.2.1. System Commands 2.2.1.1. param This command shows the parameter block content. 2.2.1.2.
This command is used to turn off WiMAX modem and RF. Before doing so, it disconnect from the network if it is already connected. 2.2.2.4. wb_ne This command is used to initiate network entry procedure when the device is in STANDBY state. This command is discarded if the device is in other states. On successful connection, the device state is changed to ACTIVE. Otherwise, it stays in STANDBY state. 2.2.2.5. wb_nd This command is used to disconnect from the network.
… [Wibro connection] autoconnection_enable=YES dhcp_enable=YES … [DM command] wb_ru … 2.3.2. Connection with static IP allocation If some base station may not support dynamic IP address allocation, you should set your IP address manually. You can, then, turn off dhcp_enable with NO, to make WiMax connection manager not try to connect. WiMax connection manager set the IP address of WiMax device(wb0) with the value of IP variable in /etc/WM.conf, if dhcp_enable in /etc/wcm.conf is defined as NO.

2.4. Configuring CPE with web browser The default settings of the CPE may need change so as to meet your individual needs. You can use crossover Ethernet cable directly between PC and CPE Ethernet port. Then, you can configure the CPE with your web browser. To access CPE, enter http://192.168.1.1 in your web browser.
2.4.1. Network configuration If you select “WCM configuration” in the left window, then you can change WCM configuration. The content will show up in the right window. The detailed explanation for the content is done in section 5.1 and 5.2. Choosing WIMAX configuration will show the following screen. This window is used for static network setup for WiMax device as shown in section 5.3.2.
For local area network in CPE, Ethernet dev, “eth0”, should be set like the following window. In this example, IP address of eth0 is 192.168.1.1 and its netmask is 255.255.255.0. IP address pool for DHCP server on eth0, “dhcpd”, starts with 10, ends to 250, and its subnet is 192.168.1. The variable, “DHCPSERVER” will control whether DHCP server will run or not.
NAT configuration in uClinux system can be changed by this window, but no change in this window is recommended.
Some users want to set up a server in local area network of CPE, that is, enabling outer world to connect the internal server, for this purpose they should set up port-forwarding method in uClinux. In this example, user can open some port with “iptables” command.
2.4.2. Firmware upgrade You can update the kernel image, file system image, and parameter block image with the web browser. This also can be updated in RedBoot mode, but it cannot be used in commercial product. So, “System Menu” in left window help you to update the images. At first, you should find a image to update with “Browse…” or “찾아보기…” button, then, you can upload the image to the CPE, and write it to flash file system with “update” button.
2.4.3. EAP configuration You can update certificate files with web access, so you click the button, “ WCM EAP Setting”, then, you can see the following With this menu, you can update the certificate files. If you click “Browse…” or “찾아보기…” button in “CA Cert File” field, then you can see the following popup menu. You should choose an appropriate CA certificate files which the service provider gives to you.
In “Client Cert File(with private key) “field, the operation is same as in “CA Cert File” field.
Then, you can see the following screen, and you can save the certificate files by clicking “save_setting” button. Other fields in the “WCM EAP Setting” menu are not effective with distributed WCM(WiMAX Connection Manager”. If you are also provided with WCM source code, you should turn on the code, “#define WCM_CONF_ENV_FROM_BINARY” in “config.h”, and recompile the source codes of WCM. Then, your executable, “wcm”, does not use /etc/wcm.conf, but uses /etc/wcmconf.dat.
Regulatory Notices Caution: The WiMAX device has been tested for compliance with FCC RF exposure limits. The WiMAX device should not be used with external antennas that are not approved for use with this device. Use of this device in any other configuration may exceed the FCC RF exposure compliance limits. To comply with FCC RF exposure compliance requirements, a separation distance of at least 20 cm must be maintained between the antenna of this device and all persons.
