This diagram shows one way to solve the problem. A second wireless access point (AP) is located in the same location with the Mac, Lemur, and Paca(rana). Those devices all connect to the second AP using Ethernet cabling.
This is what is sometimes called a “wireless extension”. A number of products can be used as the second AP but not all access points can be used. So it’s important to obtain the right product and also verify that it works with the primary wireless access point.
Apple’s Airport family has very powerful, easy to set up extension facilities, from the basic Airport Express all the way to a Time Capsule. So if you want an easy path to creating this last set up, use Apple’s access point products.
The second access point should include at least a three port “hub” or “switch” so that you can at least connect the Mac, Lemur, and Paca(rana). If you have other devices in the same location that require connection you can supplement the access points ports with an additional Ethernet switch. It is recommended to specify a “Gigibit” capable switch if you wish to use your network at top speed. An Airport Extreme is a good choice here but an equally good choice is a Time Capsule. The benefit of the Time Capsule is that you also gain a “backup server” and/or additional shared storage.
In this setup the main access point is still providing the DHCP function. The Mac, Lemur, and Paca(rana) could all use DHCP if you wish, though for reasons previously discussed the Lemur and Mac would benefit from a static IP address. Set up is the same as with the previous “unified network” description.
