Troubleshooting USB broadband modem problems

Q: No lights appear on my modem.

A: Make sure the USB cable is properly connected to the computer and is in good condition. Make sure the USB port is operating correctly, i.e. plug it into another socket and try again. Our USB modems are sent with a driver cd-rom disk. Make certain that you have installed those drivers correctly and adhered to its installation instructions.

Q: The ADSL light on my modem flashes green.

A: This indicates the modem cannot connect to the broadband network. The first thing to check is that the telephone line is working. Pick up a handset on the same line and listen for a dialing tone. If there are any problems with the line, you need to call BT's fault reporting number - 151 from any BT handset. If the line is OK, check the phone connection to the modem. Check that microfilters are correctly installed. Failing this, there may be a fault with your phone line or at your local telephone exchange.
