Just take the output cable from the wireless access point and plug it into the "Uplink" jack on the router. On most Linksys switches/hubs/routers it's the last port which is shared (so it is either another port or the uplink port).
And the difference between 11a and 11b is speed. 11b has a max speed of around 11Mbps on paper, and about 5.5Mbps in real life. 11a roughly doubles that speed as I recall. There's also an 11g which offers speeds around 50Mbps.
I have a wired Linksys Router running on Windows XP 512 RAM machine and a wireless D-Link Access Point (DWL-5000AP, the connecting instructions do not mention the Router, but the illustration on the Access Point box shows a picture of the connect from the internet to cable/DSL modem to Router to Access Point am I missing something? Any help would be appreciated. Also can someone tell what is the difference is between 802.11a and 802.11b. Thanks
