Go and configure, thanks, Hearthstone.

Sounds like they are just selling you additional IP or ports.
Will they be providing a IP for each machine? If not then a router will suffice, you will need to configure but most are real easy to setup.

Worst case you could do IP masquerade on one of the machines. Downside is that you would need addition Ethernet port on that machine;

What is IP Masquerade?

IP Masquerade is a networking function in Linux similar to the one-to-many (1:Many) NAT (Network Address Translation) servers found in many commercial firewalls and network routers. For example, if a Linux host is connected to the Internet via PPP, Ethernet, etc., the IP Masquerade feature allows other "internal" computers connected to this Linux box (via PPP, Ethernet, etc.) to also reach the Internet as well. Linux IP Masquerading allows for this functionality even though these internal machines don't have an officially assigned IP address.
MASQ allows a set of machines to invisibly access the Internet via the MASQ gateway. To other machines on the Internet, the outgoing traffic will appear to be from the IP MASQ Linux server itself. In addition to the added functionality, IP Masquerade provides the foundation to create a HEAVILY secured networking environment. With a well built firewall, breaking the security of a well configured masquerading system and internal LAN should be considerably difficult to accomplish.
If you would like to know more on how MASQ (1:Many) differs from 1:1 (true) NAT and Proxy solutions, please see the Section 7.6 FAQ entry.

Easiest would be to purchase a router to take care of the LAN, if you need more ports then get additional switch to expand.

Hope this helps.
Have fun & enjoy!

That modem may have built-in router already. Do you get a public or private IP address from it? If it is private address then all you need is a switch.

What I was trying to explain is with the typical home cable internet service the ISP only provides one dynamic IP address. The MODEM saves the MAC of the device in memory so any other computer connected via a switch to the MODEM will not be able to get online (unless you pay for additional services) which is why you need the router.

Whether you connect the laptops via wireless or wired to the router they will act independently.

I had Charter years ago, the only MAC address that played any role was the MAC address of modem itself.
