...There is an Internet Port. Is that where I connect the RJ45 connector running from the same router, and disable the router functionality to turn the Internet signal to wireless Wi-fi?
Good question, in this case you would connect the wireless router (acting as an access point) via any one of the ports *except* the WAN port.
Secondly, How could I set user access codes and/or password using the D-Link Xtreme Gigabit Router (DIR-655), acting as my AP for my users to access the Wi-fi AP with the same Router?
You would set an SSID and passphrase exactly as you would with any WiFi router or access point: http://support.dlink.com/emulators/dir6 ... eless.html
PS: Allow me to share with you what I've been trying to google and would love to here your thoughts...
The first two are small wireless routers, they would work pretty much the same as the DIR-655 I recommended except for much more limited range (less power and no external antennas) and the lack of a switch would mean that you could not connect any devices via a wired connection.
The last one is a cellular access point (femtocell
), which would only allow cellphones to connect. That is completely different from what we have been discussing so far. Scott.
