You can turn a normal router into such an access point. Before you connect it to your LMCE network, log onto its web interface and disable its DHCP server, which will also disable its routing ability. Then give it an IP on your LMCE network, jack it in on one of the lan ports, it should pass the IP giving from LMCE.
You configure you wireless settings as normal.

This is how my wireless access point is set up. If using this method, you must assign a new LAN TCP/IP if you want to be able to access the router admin page again. This wants to be in the 192.168.80.X format, and should not be an address that is already in use. I used 192.168.80.254.
