Common connection types and their speed and security considerations are:

•

Broadband Internet. Your Internet connection speed is determined by your modem type, 
(ADSL), as well as the connection speed of the sites to which you connect, and general 
Internet traffic. ADSL modem connections are asymmetrical, meaning they have a lower data 
rate to the Internet (upstream) than from the Internet (downstream). Keep in mind that when 
you connect to another site that also has an asymmetrical connection, the data rate between 
your sites is limited by each side’s upstream data rate. A typical residential ADSL connection 
provides a downstream throughput of about 1 to 3 megabits per second (Mbps). Newer 
technologies such as ADSL2+ and Fiber to the Home (FTTH) will increase the connection 
speed to tens of Mbps.

•

Wireless. Your modem router provides a wireless data throughput of up to 300 Mbps using 
technology called multiple input, multiple output (MIMO), in which multiple antennas 
transmit multiple streams of data. The use of multiple antennas also provides excellent range 
and coverage. With the introduction of the newer WPA and WPA2 encryption and 
authentication protocols, wireless security is extremely strong.

To get the best performance, use RangeMax NEXT adapters for your computers. Although 
your modem router is compatible with older 802.11b and 802.11g adapters, the use of these 
older wireless technologies in your network can result in lower throughput overall (typically 
less than 10 Mbps for 802.11b and less than 40 Mbps for 802.11g). In addition, many older 
wireless products do not support the latest security protocols, WPA and WPA2.
