There are three common situations in which the Speedtouch 330 will not work properly. It is easy to determine the nature of the problem by looking at the 2 lights on the front of the modem.
* Two green fixed lights: This means that the modem has synchronized with the exchange and that the user must now dial-up in order to connect fully. When downloading at high speeds the left light generally flashes.
* A fixed green USB light, and flashing green ADSL light. This means that the modem is not synchronizing with the Internet service provider, and is therefore unable to establish a connection. In this case, the user must check several things: (a) contact his or her Internet service provider and verify that his account is active, (
contact his or her telephone company to verify that the telephone line is active, working properly, and that it can support broadband Internet, or © make sure that working ADSL broadband filters are correctly fitted on every used telephone jack in the user's home. This issue can also arise if the modem has suffered a power surge from a thunderstorm or a short circuit. In this case, the modem must be replaced.
* A red USB light, and no ADSL light. This usually means that the modem's software and drivers are not correctly, or at all installed on the computer which it is connected to. The user must install the modem using the CD originally provided with the modem, or download the correct drivers from the Internet. This situation can also arise if the USB port on the computer is not functioning properly, or if the operating system does not support the modem (see Compatibility issues above.)
