AT-ARW256E
| Wireless ADSL Router
Up to 253 LAN Users Can Share
One Line and One IP Address
The AT-ARW256E supports up to 253
LAN-attached users – easily enough for a small
office, while high speed ADSL services mean
that they can all share a single line and still ha
ve
plenty of performance. NAT allows 253 users
to share one public IP address for low-cost
Internet access.
Intelligent ADSL Rate Adaptation
The upstream and downstream data rates are
dynamically allocated by the AT-ARW256E to
minimize noise and maximize service reliability.
For each session, the ADSL connection speed is
automatically reconfigured to achieve maximum
data throughput (within the limits imposed b
y
the service provider).
Flash Softwar
e Update
The AT-ARW256E can be upgraded simply
and quickly by loading new firmware into flash
memory using the simple, browser-based
application. New enhancements can be loaded
into the unit in a matter of seconds.
