In this tutorial, we will discuss different alternatives for linking routers in order to create wifi networks or just repeaters.
Access Point / Switch
Extend the Wireless access area using more routers, with wired connections between routers, or turn a wired port on an existing network into a Wireless Access Point. All computers will be on the same network segment, and will be able to see one another in Windows Network.
Switch - Similar config as WAP, but radio disabled (accepts only wired connections)
Repeater / Repeater Bridge
Extend the Wireless access area using a second router. Second router does not need any wired connections.
Repeater Bridge - A wireless repeater with DHCP & NAT disabled, clients on same subnet as host AP (primary router). That is, all computers can see one another in Windows Network.
Repeater - A wireless repeater with DHCP & NAT enabled, clients on different subnet from host AP (primary router). Computers connected to one router can not see computers connected to other routers in Windows Network.
