From there, you run ethernet to a local router, and then to the
central ethernet switch. The router might be built into your
unspecified model WISP radio. Note that I said
"switch", not "hub". You do not want a hub.

I had to look up hub versus switches versus routers.
- Hub: What goes in one port goes out all the others
- Switch: What goes in one port is 'intelligently' sent to another
- Router: Connects two networks to share the Internet connection

My desired setup is similar to what you've described.

- The 19 dBi planar antenna is outside on a pole pointed at the WISP AP
- (The antenna is not on the roof because I break tiles every time I go
on the roof!)
- Connected to the antenna is an outdoor Ubiquiti Bullet M2 radio
- That outdoor radio is currently configured as a router (not a bridge)
and it is set up to serve DHCP addresses and perform NAT
- From there the outdoor cat5 cable connects to a Ubiquiti 15volt POE
- From the POE, is up to me.

All I need is two wired points inside the house:
- The office (which is in a central location & where I'll put the WRT54G
broadband wireless router)
- The game room (which has a WII that I'd like to connect by wire)

I'd like the 'star' topology previously mentioned.

I'm confused if I need the "active 10/100 Ethernet switch" because I'm
wondering if the Linksys WRT54G is 'already' an active 10/100 Ethernet
switch.

Is it?
It is. See my last posting
