[routers and anyother kit?]

I have got 3 Com roouters and cisco if you want and i can config them also have cisco 1500 hub which can have IP and gateway configed

[Internet Connection sharing ADSL]

First convert your USB connection to UTP cat 5 via a belikin hub then buy yourself a Sonic firewall and enable DHCP in it, Configure the firewall to deliver Dns gateway etc and then your away.

I have this type of system at home and it works like a dream i have never been hacked "got a few people kicked of there ISP for trying"

And as the ADSl connection is always on you are fully protected as long as you config Sonic correctly.
