Network Configuration - Router- switch

Want to setup a small LAN of 12 users who will be able to connect to Internet using wired and wireless connection.

Have a cisco 1841 router and cisco 2960 switch and a linksys wireless router.

I am bit confused about setting up DHCP for wired and wireless router.

1. I plan to connect the wireless router to one of the switch ports.
- What will be the wireless router IP ?
- Can I assign a public iP to it ?

2. How to I setup the DHCP IP range on the wired router and wireless router ? I believe they will be different network altogether.

One approach might be to have the 1841 connect to the WAN via you assigned public IP range then have a second interface connect to 2960.  Then see if you can connect your linksys wireless as a standalone Access Point (no router functions needed) connected to 2960.  If you don't have a server able to hand out DHCP then configure it in the 1841.

Shall get the 1841 to hand out DHCP.

Didnt understand how to connect the linksys wireless as a standalone access point. Wont it issue out its own set of IP addresses as DHCP.
Hi TechGuy,
Your confusion is justified.. I recommend you setup your Router to assign IP addresses based on the MAC address of your devices... Assign different IPs for your wireless and wired computers... Normally your computer will choose the wired as the priority connection if they are both connected.

As for any additional access points or routers - they should all have DHCP disabled... in the settings you should point the dhcp server to your main router. If you have two routers handing out DHCP addresses you will have major problems.

Does this make sense? Hope that helps.
I have a similar network in my home with the following hardware; Cisco ASA 5505 firewall and a Linksys Wireless router. I use only the DHCP server of the firewall on all computers and it works great. My Linksys uses the .1 IP and the firewall gives away a default gateway that is the firewall .254
