Connect two wifi-routers for "meeting room" LAN
I have two wifi routers. Each has an integral 8-port 1000baseT switch.
Can I connect computers by wire to one wifi-router; connect computers by wire to the other wifi-router; and use the wireless to interconnect the two routers so that all computers are a single LAN? Is this what they call a "wifi bridge?"
Assuming that I can do this, do I need special antennas for the point-to-point connection? Are they "required" or simply "benificial?"
If I use this sort of wifi interconnection, does the wifi remain available for wondering connections or do I need still other wifi "access points?"
If someone has done this before, I'd appreciate recommendations and discussion and suggestions.
