Re: Need help w/ Speedstream 4100 and WRT610N

It seems my big mistake so far was cloning the modem MAC address instead of the PC MAC address
I agree that should be your next move

For the life of me I don't understand why ISPs still think it's ok to tie your service to one PC MAC address... meh. It would seem to make more sense to register the modem's MAC since that's the single point into the home.
I don't see the need to associate with a mac address at all
I'm pretty sure the isp/telco can map the physical/virtual path for each and every customer end to end

Based on my participation in the »Westell forum, it seems that in DHCP regions, Verizon does associate an account with a MAC address. The first MAC address used to acquire an IP is apparently put into the DHCP table, and that's the only MAC that is going to get an IP for that particular connections.

The ways around this are:
(a) Turn off everything and wait till the DHCP table entry expires - I'm not sure, but I seem to recall that somewhere around 24 hours is enough.
(b) Call Verizon support and ask them to manually reset the account (delete the DHCP entry).
(c) Clone the old MAC address into a router, and use that router.

In this case the best option seems to be (c).

Note to the OP: When the modem is being used as a bridge, the MAC of the modem has no particular significance. Rather, it is the MAC of the connecting computer that the ISP will see.

Verizon is probably using off-the-shelf DHCP server software that is built around using a MAC for assignments, and in bridge mode the MAC seen will be that of the PC. If you had been using a Verizon supplied Westell 6100 modem and had it set as a "routed bridge", then the 6100 would act as a router and Verizon would see the MAC of that 6100. However, the 4100 you are using does not have a corresponding mode. Verizon users in a DHCP region, who change their 6100 to an unrouted bridge mode, usually run into the same problem that you are seeing.

I'm aware of your activity in the westell forum and that verizon uses dhcp in some of its regions

In my reply I was trying to point out that I don't think its nesscary for isp's/telco's to serve a ip based on a mac address
