Option 1:
Each PC has a separate ISP account, and operates
independently. No data sharing. Each PC has its own dedicated
WiFi adapter.
Option 2:
One PC is the "gateway" and the others connect to the single
ISP account through that machine with Ethernet cables.
Option 3:
A WiFi Gateway/Router manages traffic from each of the three
PCs over wired Ethernet cables. Only one ISP account.
Option 4:
A WiFi Gateway manages traffic from the ISP to a second
WiFi access point (on another channel on the 802.11G radio
band). Each of the three PCs connect by wireless WiFi the
access point. Only one ISP account.
