I have a small wired LAN (5 - 10) computers with a router that provides DHCP service. I wish to hang a wireless hub off the network. Can I configure the wireless hub just to pass the DHCP requests thru to the router and not try to do it himself? Do I need to set the wireless hub to get its own IP address from the hub? Is there a brand or model that could be recommended? Anything else to worry about?
You need a standalone wireless access point (WAP). The WAP device is a bridging device that plugs into a LAN port on the router and bridges the wire and wireless networks together, allowing the wire and wireless computer to share resources with each other and allows the wireless computers to use the wire router as a gateway to the Internet, just like the wire computers. The wireless computers would get their IP from the DHCP server on the wire router.
Linksys, D-Link, arid Netgear are some and there are others too that have WAP devices you can look it.
I know what you're trying to say, but I found this confusing:
DSL modem > hub > Linksys WRT54G LAN port.
To be clear, let's express it like this:
DSL modem > Router/hub > Linksys WRT54G LAN port
So the ethernet side of the DSL or cable modem goes into the WAN port of your NAT router, which should have 4 or more ethernet LAN connectors via it's built-in hub or switch. One of those should go to one of the LAN connectors on the Linksys WRT54G. All of the other LAN connectors (on both the NAT router and on the WRT54G) can be used to access the local LAN segment via the usual kind of wired ethernet cables, and nearby WiFi equipment should also be able to connect. The WAN connector of the WRT54G will be unused. If you don't turn on encryption, then your WiFi setup is "public", and anybody can use it. To turn on encryption, you'll need to assign an IP address to the WRT54G (from the same subnet managed by your NAT router) so you can use your browser to set it up. WPA encryption is far stronger than WEP encryption if you use a good encrypting passphrase, but it is less compatible with older WiFi equipment.
