There are three types of ADSL modems. They are the ethernet ADSL modem, the PCI ADSL modem, and the USB ADSL modem. The ethernet ADSL modem can be fed directly into a PC ethernet port or used to add a modem to certain broadband routers. The PCI ADSL modem fits inside the computer. USB ADSL modems are the most popular form of all ADSL modems, and they are designed for connecting individual computers to ADSL lines. The download speed ADSL provides is variable, depending on your distance to the central office or to a remote router. The maximum download speed of eight mbps is only possible if you live within one mile of the office. The typical ADSL subscriber can expect download speeds of up to four mbps. |
