Click on terminal icon in Pannel, than type su, Enter and than type ifconfig.
Which modem is yours:

SpeedTouch 510E Single port ADSL Ethernet router
SpeedTouch 530 USB / Ethernet ADSL router
SpeedTouch 510switch Four port ADSL Ethernet router
SpeedTouch 545 Wireless ready ADSL Ethernet router
SpeedTouch 570 Wireless ADSL router

It seems that every of them is router. As Harry said, this is very good.
