Thanks all,
JackMDS, some good info.
cparker, I already read the belkin site. (same as you a bit confuse)
As I said, the wireless router F5D7230-4 can act as a AP. BUT you need a CAT5 to connect them together to make it work. My interested will be without the wired connection, will it act as a "wireless" access point.
F5D7230-4 has 10AR all the time (if rebates all back. I got one during BF at CC 5 AR)
Currently the f5d7130, cheapest is at officeMax with 20 Rebate for $50.
one F5D7230-4 and one f5d7130 should works. but two F5D7230-4....
Quota as the first link of JackMDS gives:
"Scenario 2: A "normal" two floors house. The Internet Modem and the Router are in the Den and the signal can not cover the whole house, it usually covers the Computer room and the direct rooms next, sideway, and above.
Additional Access Point was installed and physically put on a high pedestal near the staircase in the hallway. The AP was connected to the den's Wireless Router with a long CAT5 cable. The result a total converge of all the house with good Wireless signal.
As oppose to the solution in Scenario One, putting a better Antenna on the Wireless source in a multi level multi room envioroment, would not benefit as much as adding a second unit in a better location.
Cost: $20-$40 for Wireless Router (used as an Access point) + $8 for CAT5e.
Since the price of Wireless Routers is much lower than the price of Access Points. Many people extend the coverage by connecting a second Wireless Router, configured as an Access Point, to the primary Wireless Router that is connected to the Internet modem.
