Hi all,
in windows 7, from explorer, network, network infrastructure, you can see 
the type of router/modem that the system detects. Example Netgear 834.
You can also see the connections and sharing center, click on link on the 
top right, shows the complete map.
Left click on gateway and by clicking property you can see the router name 
and model.

Wanted to ask what is the command to obtain the same result by command 
prompt .
Thanks to all for any replies.

Greetings.
