Description of the PRESTO Advanced GPRS/EDGE/HSPA Router Series
PRESTO Advanced routers represent a robust solution designed to provide remote connectivity
across cellular networks. Low transmission delay and very high data rates offered by existing cellular
networks completely eliminate the need for expensive wired infrastructure. PRESTO Advanced series
brings scalability of even most demanding corporate networks on highest possible level. Installing a reliable,
high performance backup solution for existing land lines or satellite networks is now a simple task thanks to
modern cellular networks. Therefore, no matter if the goal is to provide primary internet access or backup
solution for already existing network PRESTO Advanced router series represents a top rated solution.
There are practically no limits when it comes to possible application of PRESTO Advanced routers.
Wired infrastructure is no longer necessary for building scalable and high performance systems. PRESTO
Advanced routers will reduce the costs and speed up the ROI process for each one of possible applications.

Top Panel
There is a sequence of 8 LED indicators on the top of this device by which the indication of the
system current state, device power supply and presence of GSM/UMTS network as well as signal level is
performed.
LED Indicator Description:
1. Reset (red LED) on –the PRESTO Advanced Router reset state.
2. Power status (green LED) on –Power supply. Power status LED will blink when the PRESTO
Advanced Router is in initializing state.
3. Link (red LED) will blink when connection is active.
4. Signal strength LED indicator:
–107 or less dBm = Unacceptable (1 LED)
–107 to –98 dBm = Weak (2 LED)
–98 to –87 dBm = Moderate (3 LED)
–87 to –76 dBm = Good (4 LED)
–76 or better dBm = Excellent (5 LED).
0 is not known or not detectable (running LED)
Signal strength LED will blink when GPRS/EDGE/HSPA connection is not active. When
connection is active Signal strength LED is on. Reset condition will be indicated by blinks of the first

Device Configuration
There are two methods which can be used to configure the PRESTO Advanced Router.
Administrator can use following methods to access router:
Web browser
Command line interface
Default access method is by web interface. This method provides administrator full set of privileges
for configuring and monitoring the router. Configuration, administration and monitoring of the PRESTO
Advanced Router can be performed through the web interface. The default IP address of the router is
192.168.1.1. Another method is by command line interface. This method has limited options for configuring
the PRESTO Advanced Router but still represents a very powerful tool when it comes to router setup and
monitoring. Another document deals with CLI commands and instructions.
Device configuration using web application
The PRESTO Advanced Router’s web-based utility allows you to set up the Router and perform
advanced configuration and troubleshooting. This chapter will explain all of the functions in this utility.
For local access to the PRESTO Advanced Router’s web-based utility, launch your web browser, and
enter the Router’s default IP address, 192.168.1.1, in the address field. A login screen prompts you for your
User name and Password. Default administration credentials are admin/admin.
If you want to use web interface for router administration please enter IP address of router into web
browser. Please disable Proxy server in web browser before proceed.
Figure 4 - User authentication
After successfully finished process of authentication of Username/Password you can access Main
Configuration Menu.
You can set all parameters of the PRESTO Advanced Router using web application. All
functionalities and parameters are organized within few main tabs (windows).

Settings - DHCP Server
The PRESTO Advanced Router can be used as a DHCP (Dynamic Host Configuration Protocol)
server on your network. A DHCP server automatically assigns available IP addresses to computers on your
network. If you choose to enable the DHCP server option, all of the computers on your LAN must be set to
obtain an IP address automatically from a DHCP server. (By default, Windows computers are set to obtain
an IP automatically.)
To use the PRESTO Advanced Router as your network’s DHCP server, click DHCP Server Tab for
DHCP Server setup. The PRESTO Advanced Router has built-in DHCP server capability that assigns IP
addresses and DNS servers to systems that support DHCP client capability.
DHCP Server Parameters
Label
Description
Enable DHCP Server
DHCP (Dynamic Host Configuration Protocol) allows individual clients
(workstations) to obtain TCP/IP configuration at startup from a server.
When configured as a server, the PRESTO Advanced Router provides TCP/IP
configuration for the clients. To activate DHCP server, click check box Enable
DHCP Server. To setup DHCP server fill in the IP Starting Address and IP Ending
Address fields.
Uncheck Enable DHCP Server check box to stop the PRESTO Advanced Router
from acting as a DHCP server. When Unchecked, you must have another DHCP
server on your LAN, or else the computers must be manually configured.
IP Starting Address
(From)
This field specifies the first of the contiguous addresses in the IP address pool.
IP Ending Address (To)
This field specifies last of the contiguous addresses in the IP address pool.
Lease Duration
This field specifies DHCP session duration time.
Primary DNS,
Secondary DNS
This field specifies IP addresses of DNS server that will be assigned to systems
that support DHCP client capability.
Select None to stop the DHCP Server from assigning DNS server IP address.
When you select None, computers must be manually configured with proper DNS
IP address.
Select Used by ISP to have the PRESTO Advanced Router assign DNS IP address
to DHCP clients. DNS address is provided by ISP (automatically obtained from
WAN side). This option is available only if GSM connection is active. Please
establish GSM connection first and then choose this option.
Select Used Defined to have the PRESTO Advanced Router assign DNS IP address
to DHCP clients. DNS address is manually configured by user.
Static Lease
Reservation
This field specifies IP addresses that will be dedicated to specific DHCP Client
based on MAC address. DHCP server will always assign same IP address to
appropriate client.
