Configure the Router to Use a USB Modem

Once you have flashed your router to use the ROOter firmware and have finished configuring the router functions, it is time to configure it to use your USB modem.

Do not plug the modem into the router until this configuration is completed.

Log on to the ROOter web interface and select the Modem menu and Connection Info submenu.

GoldenOrb allows the use of two modems so you must fill out the information for each modem if you plan on using both. Otherwise, only Modem 1 needs to be configured.

Here you can fill in the boxes with information required to allow the modem to connect to the Provider's network and to add some custom features to the process.

Enter your APN in the APN : box. This is required to make a connection and the name is supplied by your Provider. Note that hostless modems don't require this. For most providers and modems this is all that is required to make a connection.

If your Provider requires a User Name and Password, enter them in the appropriate boxes. Otherwise they can be left blank.

If a User name and Password are required then the Provider will have stated the type of Authentication Protocol to use. This will be PAP or CHAP. Use the dropdown box to choose the correct type.

If your SIM is Pin locked you must enter the correct code in the PIN field.

At this point, you have entered all the required information to achieve a connection. Click on the Save button in the lower right corner and wait for the changes to be applied.

You can now plug in your modem to the router and it will automatically connect to the Provider's network. This can take up to 2 minutes to complete, depending on the modem.

If you leave the modem plugged into the router and reboot the router by powering off and then on, the modem will also automatically connect to the Provider's network after the router has completed its boot up process.

Custom Connection Features

If you wish, there are a number of custom connection features that can be enabled. This are normally okay using the default values but they can be changed if need be.

Connection Delay in Seconds

Connection Delay in Seconds allows increasing the delay after the modem starts the connection procedure and when it actually does the connection. This applies only to modems not using the PPP protocol.

The delay must be at least 1 seconds or you will not be able to save it. The delay may need to be increased if you are having problems getting your modem to run the connection sequence correctly.

This feature is seldom needed and should be used only as a last resort. It will not cause any harm but will slow down the connect procedure.

If you change this value, click on the Save button and wait until the changes have been applied.

Force Modem to PPP Protocol

Force Modem to PPP Protocol allows you to force your modem to use the PPP protocol rather than the high speed protocol it would normally use.

By choosing Yes you will force all modems to use the PPP protocol. This can be useful if your modem would normally use another protocol but refuses to connect while using it.

If you change this value, click on the Save button and wait until the changes have been applied.

Custom DNS

Custom DNS servers can be specified so that they override the DNS servers used by your Provider.

The order in which custom DNS servers are used is :

  • those defined in the LAN interface
  • those defined here
  • those provided by the Provider via the modem


You can enter either one or two DNS servers you wish to use. If you enter two servers then the primary DNS server will be DNS Server 1. The IP Address is checked for correct format and will be rejected if it is incorrect.

If you enable this feature click on the Save button and wait until the changes have been applied.

Lock to Provider

If you wish to have your modem connect only to a specific Provider (not allow roaming) then select Yes in Lock Connection to a Provider. When you do this two more fields will appear.

You must enter the Country and Network codes for your Provider and then click on the Save button and wait until the changes have been applied. See here for a list of Country and Provider codes.

Other Settings

Other setting that can be altered in the Connection Info page are Connection Logging and Custom AT Startup Command at Connection.

Connection Logging, if enabled, will display all the AT Commands used during the connection process in the System Log. This can be useful when debugging connection problems.

If you enable the Custom AT Startup Command at Connection you can have the router sent an AT Command to the modem right before the connection process starts. This command is defined in Custom AT Startup Command. A knowledge of AT Commands and your modem is required before using this.
