I just discovered today that I'm not able to acquire an IP address from the core DHCP server using the wireless card in my laptop. I'm able to acquire an IP just fine if I use the physical ethernet connnect. Here's my setup:
Cable Modem ->Wireless Router (DHCP disabled) ->DCERouter (DHCP server)
->VOIP Modem (wired connection)
The DCERouter(core) has a single NIC card. The Laptop and VOIP modem can acquire IPs in the 192.168.80.xxx range just fine. When I disconnect the ethernet cable on the laptop, it can see the wireless router just fine, but it can't acquire and IP from the core. Should this setup work or am I missing something?
