Need your help: Segregating a network to restrict resources available for Wireless access...

I need some community help on this - I'm flying seat of my pants and have become responsible for a small office network at a summer camp. All well and good until the camp decides to add some wireless access and wants it separate from the existing network. Thus, I need a way to separate the network into 2 parts, both of which have internet access.

Segment A is the wired 100mb/s office LAN. Machines in this segment need to have access to the Internet and each other for file and print sharing. Some of the machines are running Win98. Less than 15 machines total. (Right now, everything is connected to this segment, including the access points, and TCP/IP carries all the network traffic, both file and print sharing and Internet stuff.)

Segment B will be made up of 4 wireless access points (DLink DWL-900+). Computers that access this segment should only have access to the Internet - in fact, that's a must. I don't want users on the wireless getting into the Segment A office resources. (I don?t mind if someone nearby jumps on the wireless, as long as they can?t get on the main office resources, so 802.11 security is not a big worry?)

Right now this network is set up and running using a Linksys Router to talk to a DSL modem and the outside world. On the inside, the Linksys router handles the DHCP for the network. It is a BEFSR81 and appears to only handle one range of private IP addresses at a time.

A few of my questions so far: If I add a second router for segment B, how do the two routers talk to each other? Do I need yet a third router to talk to the DSL modem? If I use two different private IP ranges with a common subnet, will that prevent one group of machines from seeing the other?

I'm something of a network newbie but I'm already sick of reading "how to" articles on home networks - I need to know how to get this up and running by next week! Ideas and network descriptions/topologies greatly appreciated!

The only way I could make that work is with a unix router and 3 NIC cards. The experts will stop on by and tell you how to do it with subnetting, maybe.
 
Sounds like you need a domain controller. 2k server box with AD set up properly would do it...but I have a feeling that that is beyond the scope of what you want to do. I don't know how to do it any other way, though.
 
To be honest the easiest thing to do would be to get a second DSL or cable modem andpay for access through it as well. (that is if money isnt an issue)
For the extra $40 a month, you would be completely seperate without any hassles.

Yep, otherwise you're looking at a configuration nightmare.
 
Not to mention the hardware you would need to buy to setup a linux server if you dont have any laying around.

Yes, I would not want to do that without any experience on a week's notice either.
 
You can't use subnetting with the Linksys...I contacted them because I wanted to do it and they told me NO.
I was stubborn & tried it anyways...well, I should have listened 😱

Anyways, the easiest way would be connecting a firewall between the wired/wireless segments. A router might do, but be sure to configure it right.
