starting up - just starting out...clue please ?

Hi Folks.
Using a spare PC with ample CPU/RAM/HDD I installed the 'home' version, and then noticed that how it ID'd the onboard & plugged in network interfaces was not decipherable to me.

Since it ID'd one as an RTL I knew the MB had some RTL and I plugged the cable for the LAN there when it restarted - but couldn't ping it or reach it's IP via browser.
Proceeded to un- and re-plug the cable into the other RJ45, same result.

Questions, please (please be gentle as I've NEVER used this before !?):

1. Does the ASG require a reboot or manual entry of commands to change what is plugged into each NIC (so it logs in or whatever...) ?

2. When later one adds another NIC for another function - will the ASG recognize a new card and easily allow assignment ?

3. Precisely where might I find instructions for later adding wireless access in the house and also for allowing some means of file sharing for when I am at work, remotely ?

I ask some of this because I searched both sites and found no clear answers to the above - but also because it seems the KB is only accessed via search and there is no obvious listing place for docs that I could find....?!

Thanks.
