Emerald :
WAP is a Wireless Access Point which is connected to the rest of the network via network cable.
You are talking about a Repeater Bridge which connects wirelessly to the main router and retransmits the signal and provides LAN ports.
Or are you talking about a client Repeater which connects wirelessly to the main router and provides LAN ports but no wireless.
do you already have a second router? if so what model?
If you still need to buy, look at an ASUS RT-N12. To build a bridge or client repeater you will need a router that can support DD-WRT firmware

So I guess what I need is what you call a "repeater" which connects wirelessly to the main wireless router, and retransmits the signal. Also when you say, " and provides LAN ports", do you mean that I can use, say another PC to connect via Ethernet wire to the repeater in anyone of its free LAN Ethernet ports?
I don't have yet the second router to use, but I thought any router should work without the need to support a specific firmware as you mentioned "DD-WRT". Again, thanks for the clarification, for I did not know the difference between a WAP and a REPEATER. Btw, I am running Windows 7 Professional 64-bit version just in case this may help me with my network. The other 2 people using my LAN, one uses Windows Vista, and the other Windows 7 Home.
