Q. What should I do it encounter the error message "Can't Analyze USB Modem"?

Please make sure you are using the latest router tools and router firmware. You may download the latest versions here.

Next please check if you have uploaded the modem firmware using the supplied utility "DSL Modem F/W installer". This utility copies your modem's firmware from the PC into the router. You must run this utility from a PC which has the USB modem drivers already installed.

You may try to surf the Internet from that PC through the USB modem to ensure the modem is correctly installed Remember that the Vigor2200USB only supports certain USB ADSL modems - you may check the compatibility list.

For the Globespan chipset based modems (e.g. Intel, Westell , Fujitsu). The DSL Modem firmware utility (V2.6 with router firmware 2.2 and later) is able to create a line synchronization file for your line.

This may be necessary if the line parameters are unrecognizable by the router and is not normally necessary - try the default (and simpler ) method firstly. The utility will guide you through the process. There are three methods available:

Default - The F/W installer will use it's default sync. file. Try this method first.

Create - By monitoring your modem while you connect/disconnect it to the PC and ADSL line as instructed, the utility will build a line synchronization file.

Load - You can use a line synchronization file that you, or someone else, has created previously.

If you use the 'create' method, the utility will ask you to disconnect the line and modem from the PC and then reconnect each as instructed on screen. It is important that before you start that process, you ensure that then modem is set to G.DMT mode rather than multimode.
