One day i might buy a Tyros (have Roland G70 currently)

To access broadband i have a TalkTalk modem (ADSL) which connects to my PC lan port

If and when i buy a Tyros X can i use this modem (it only has 1 lan port which requires special PC software as far as i know to connect to the WWW)

Can i just switch the lan wires from PC to Tyros or is there more to it ?

Thanks in advance to anyone who can and does answer this
