View Full Version : Advice needed: Extending existing wired LAN with wireless AP

08-06-2005, 09:22 PM
We have four PC's connected via a wired LAN to a Billion 7100 ADSL modem/router and a jetstream connection via IHUG. We'd like to be able share the broadband wirelessly to a PDA, preferably by way of some sort of access point so none of the PC's need to be on. It would also be useful to extend the number of RJ45 points via a switch, as it would be good to add the printer to the network (it has a network capability), and of course adding the WLAN will also take up a port on the router.

The existing router has a built in DCHP server, so I think that other devices do not require this function. If we add a 'dumb' wireless access point, and a normal network switch to extend the number of RJ45 ports, would these both piggyback off the DCHP server and other features of the router?

Note that we'd prefer to keep the PC's wired for now (as the obvious answer to the switch question is to make one or more of the PC's wireless).

Any advice would be appreciated.

A lot would depend on the AP that you are using... I think I know what you mean by "dumb AP" but I'm not sure if they are availible, except in the higher end of the market(I know Cisco make them at ~$400 a pop, but they are really good).

It would probably be easier to have a look at some manufactures websites and hit their tech support team for some help. Linksys(owned by cisco) make some great gear, same sort of quality as cisco gear, but considerably cheaper.

Put a switch between the router-modem and the PCs. You can then connect an AP and a printer, as well as the PCs, to this switch.

I'm not sure about DHCP, but I assume it should work via the AP. If it does give you trouble, turn it off and assign all the clients static, internal network addresses.

As for choice of APs, I am shocked by the cost of those things. If you know linux/bsd, or are willing to learn/experiment, you can make one out of an old 486, plus the wireless cards. See this site (http://www.Linux-Wireless.org/Wireless/AP/) for instructions.

dse does an AP for about $100 as seen here (http://www.dse.co.nz/cgi-bin/dse.storefront/42a78c8609a72838273fc0a87f990720/Product/View/XH7988)

This (http://sal.neoburn.net/imagef1/files/wireless-network-topo-Rob99.gif) is how I have set mine up.

Modem = Dlink 302 - supplied by xtra
Switches = cheap Genius 5 and 8 port
Accesspoint = Linksys WAP54g

This setup works both DHCP and setting up manually.
I set mine up manually, this (http://pressf1.pcworld.co.nz/showthread.php?t=58591) is the thread where I asked a few questions, may be of help for you.

Just noticed you want to set-up a networked printer as well, I would have to say setting the IP's manually is the best option for you.
