Netopia 3347-02 no internet connection after LAN config changes

Experts,

I'm having a problem with a Netopia 3347-02 router that I'm hoping you can assist me with. Whenever I change the DHCP server to a local IP range such as 192.168.1.50 - 192.168.1.80 with a subnet of 255.255.255.0, the router passes out addresses properly to the machines that are connected to it. The problem is that each machine loses it's internet connection.

The IP of my Netopia is 192.168.1.254. I can see through IP config that it's assigning an IP like 192.168.1.52, subnet of 255.255.255.0, gateway of 192.168.1.254 and dns server of 192.168.1.254.

Please help! Thank you!

I don't know Netopia very well but this is what I would look at:
Check to ensure the router is in gateway mode (not bridge mode).
Check the WAN settings in the router - is it Statically assigned an IP, of is it getting the IP from the ISP (is DHCP client turned on)?
It sounds line when the DHCP server is not changed to a local IP range, it works.
What range do you set it to for it to work?  Or do you turn if off to work?

Thanks dosdet2!

I'm headed to the office shortly so I will check all of your suggestions.

When I set the DHCP to pass out local addresses the addresses are passed out correctly but the client has no Internet access. When I set DHCP to pass out the 5 WAN addressed that the ISP sent me the clients have no problem.

The WAN address is static from the ISP.

It sounds like the router is in bridge mode.

I spoke with Motorola about this problem and they actually gave me two links to setup the modem which I followed:

Unfortunately, I was still having the same issue where my clients were receiving the proper IP scheme but still had no Internet access. I went ahead and purchased a router to attach to the modem and was up and running in less than an hour.....

In the world of WAN, QoS is a pretty important topic for most, if not all, networks. Some WAN technologies have QoS mechanisms built in, but others, such as some L2 WAN's, don't have QoS control in the provider cloud.
