Changes between Version 42 and Version 43 of Old/WiMAX/30

  • Old/WiMAX/30

    v42 v43  
    276276If ordering through Advanced Circuits it is a good idea to run the design through the automated [ FreeDFM] service. The design has already passed the check, but it also creates a quote matrix and populates any additional information on the board. [[BR]]
    277277To have the board populated with parts send the additional zip file ( for quoting. The bill of materials (BOM) currently lists the right angle SMA header as not in use and 'do not install', if you wish to use it change that line in the BOM.
     279== 12.3 Configuring a Teltonika WiMAX USB Card to Ping NEC from an Ubuntu Host ==
     281=== 12.3.1. Install Driver / Eject "CD-ROM" ===
     283When first inserted into a new computer, the Teltonika device is mounted as a CDROM. It will immediatly begin installing a driver on host machine. On Ubuntu this process is non-obvious; allow the computer to sit for 5 minutes after inserting the device to give the driver time to install.
     285After the time to install has passed, determine the device that the "CDROM" is associated with by running:
     288$ dmesg
     291Somewhere near the bottom of the messages should be a message that contains "Attached scsi CD-ROM [device]". This
     292interface must be ejected so that the device can act as a wireless transmitter rather than a CD-ROM. In most instances the CD-ROM will be associated with either sr0 or sr1. Eject the device using the command:
     295$ eject [device]
     298After a few moments a notification about a new ethernet interface becoming available should appear. This is the interface that the computer will use to communicate with the wireless dongle.
     300In some cases after this initial setup was completed the computer would always recognize the device as an ethernet interface, and sometimes the CD-ROM device would need to be ejected each time. Reasons for this difference is unknown at the time of writing.
     302=== 12.3.2. Update Firefox (or Google Chrome) ===
     304A web interface is provided to configure and interact with the dongle graphically. This webpage requires the most
     305recent version of Adobe Flash. To update/download Firefox and the Flash plugin run:
     308# apt-get install firefox flashplugin-installer
     311NOTE: Adobe has announced that it will no longer support Flash for Linux, and so in the near future Firefox may have depreciated Flash support. In this even Google has commited to maintaining Flash for Linux in it's Chrome browser, and it can be used as a viable alternative to Firefox.
     314=== 12.3.3. Connect to the WebUI ===
     316If the the Teltonika dongle is recognized as a wireless interface open up the WebUI in Firefox or Chrome by navigating to . If this IP address does not direct the browser to the WebUI then ask the previous user of the device for the new address, it is a configurable parameter and may be changed.
     318Login as an administrator by CTRL-SHIFT-Clicking the Teltonika banner at the top of the page. Login credentials are also configurable, but are most likely set to:[[BR]]
     319username: admin[[BR]]
     320password: genipass[[BR]]
     322Other passwords may be: admin OR EifAFKt8
     324=== 12.3.4. Configure Device ===
     326The device can be configured to look for networks on a number of channels under the WiMAX->Channels tab. The GENI network has the profile:
     328Frequency (kHz): 2590000[[BR]]
     329Bandwidth: 10000[[BR]]
     330FFT: 1024
     333Other configuration parameters can be configured by altering the file, found under the Files tab of the WebUI.
     335'''WARNING:''' it is entirely possible to brick the dongle if parameters are altered in this file in a way that should not be.
     337It is fairly safe to alter the fields: ipaddr (IP address where the WebUI can be reached), netmask (Subnet mask that the device will operate on), dhcpdsip (DHCP server IP address), dhcpdeip (unknown meaning at time of writing, may be expected IP address from DHCP server).
     339=== 12.3.5. Statically Set Device IP Address ===
     341Telnet to the device:
     344$ telnet [WebUI address] 700
     347The login credentials for the telnet session are:[[BR]]
     348username: admin [[BR]]
     349password: admin01
     351Within the telnet session run the following command to statically set the devices IP address:
     354# ifconfig icc0 [desired address] netmask [desired netmask]
     357This static address is not preserved when the Teltonika device is removed from the host machine, and it needs to be configured each time that the device is connected to the host.
