Resetting router 

•

 

Turn router on and wait for ADSL LED to lit or start blinking. 

•

 

Press and hold 

RESET

 button on the back panel of router for 5-10 seconds and then 

release it. 

•

 

After reset LEDs will return to their normal behavior and all settings will be reset to their 
default value. You can login to router configuration page using default username and 
password: admin / pentagram. 

 

Connecting Cerberus to Computer. 

Cerberus can be connected to computer via Ethernet or WLAN: 

Connecting via Ethernet Port (Ethernet Card) 

All Ethernet ports of router are made in the technology, which automatically activates 
Crossover if necessary. Thanks to autonegotiation of connection speed the router will 
automatically select the maximum available speed rate. Transfer at 10/100 Mbit/s rate  
requires the category 5 cable wired with RJ-45 connectors. In case of "straight" cable both 
connectors must be crimped in standard EIA/TIA 568B. In case of Crossover cable one 
connector must be in standard EIA/TIA 56A, and the second in EIA/TIA 568B. After connecting 
the device to one of the ports, corresponding LED will begin to blink. That signals the process 
of the auto-checking of port and the negotiation of connection speed rate. 

Connecting via WLAN Interface (Wireless Card) 

To connect PC to Cerberus via WLAN, Wireless Adapter must be properly installed and 
configured and both router and PC must be in the same subnet. 
 

Configure TCP/IP 

After connecting the computer to the router (by LAN adapter or WLAN Interface) the TCP/IP 
protocol should be configured. The protocol should be automatically installed together with 
Network card drivers. It is advised that TCP/IP should be configured to receive IP address and 
all the necessary network parameters from DHCP server automatically. You can find step-by-
step configuration for different Windows systems below. 
 

Note:

 In some cases computer with Windows Vista or Windows XP SP3 cannot obtain an IP 

address from router’s DHCP server. If you encounter this, follow this steps to resolve this 
problem (Microsoft Support page)
