So I have a pretty large house that use to be connected to a business network that had a DHCP server. However we've disconnected that business network and put in residential internet so I need a new way to assign DHCP to all wireless clients.
The new internet connection in the house has a modem (Motorola Surfboard SB6120) that when anything is attached to the ETH port it assigns it the public IP address (like my laptop for example). I have three 3Com wireless access points (business class I think) that all broadcast the same SSID so they can hop from one to the other without the clients even realizing it (depending on which part of the house they are in). They do NOT assign DHCP (even though they could if needed).
I need to put something in between the cable modem and these 3com access points to assign DHCP addresses. Whenever I look for a router they all seem to be wireless, which I really don't need (becuase I have the 3coms). Is there something I can buy that I could put in between my cable modem and 3com WAPS to assign DHCP and still use my 3com access points? I don't think having all three 3Com's assigning DHCP would work would it?
