I’ve learned more about networking in the last week than I did in the past year.
DSL modems, such as the Westell Wirespeed, typically assign IP addresses based on MAC address. The MAC address is supposed to be a unique identifier for every piece of networking equipment. Of course, I’d always known some ISPs limit usage based on MAC address filtering. What I didn’t know is that MY ISP did, and the way in which they did it.
When the modem has assigned an IP to a requester, it won’t give out any more IPs. It will only give out one IP to one and only one MAC address.
This is the basis of the problem I ran into while trying to switch/upgrade wireless routers.
My old router is a Netgear 802.11b wireless router, and the new one is a ZyXEL 802.11g P-330W. At first, I thought there wasa a problem with the ZyXEL router. I was so certain of this that I even took it back to CompUSA for an exchange.
It turns out that the connection from the DSL modem doesn’t even work when connected directly to a computer.
This means it wasn’t really the router’s fault it couldn’t get an IP address. No computer can either, which means it’s on the DSL modem/ISP’s end. Their routers which assign IP addresses to customers’ DSL modems is not working properly. It doesn’t clear the MAC address assigned unless the networking device (identified by its MAC address) expressly releases the IP.
Some network cards have the ability to spoof their MAC address from within Network Connection Properties -> Configure -> Advanced. Dell computers do not (tested on Dimension 4600 and Inspiron 700m built-in network adapters). Please leave a comment if you can help with battery can`t be identified inspiron 700m.
The ZyXEL router doesn’t have a feature to release its IP address, but it is able to clone MAC addresses. So I was given the MAC address by the Verizon operator and was then able to get an IP assigned by DHCP. I hope this has helped you with verizon dsl modem password.

Same problem, with the ip address, needed 159.153.235.1 or 169.153.235.2. After reading your post, and learning about the Mac ip being the problem, and you contacting who, by phone, and resolving the problem. Would I call Verizon, who supplied me with the router a Westel Model # 327W. I am about at the end of the road with this, trying to access my Pogo Game site, which I had been on for years. But now it is blocked by a firewall from a port, and they are saying to find another port, duh? But also the above info you provided me with, another suggestion by Pogo about the IP address. So Here I am and thank you mucho for you figuring out what to do and posting it here.
Was having the same problem, in that I have the Westell B90-210015-04 (2100) modem with a D-Link wireless “B” router and I wanted to upgrade to a new Linksys “G” router. I had internet service coming out of my D-link router via wireless, but I could not get it directly out of the modem through the ethernet cable or USB cable directly to the pc. I spent hours trying to fix it by shutting everything down, restarting, switching cables, testing cables, repairing the network connection,everything. I even went into my router configuration and released AND renewed my IP address. I didn’t realize that I was on to half of the solution.
Based on what I read here, I went home and got back into my router configuration (192.168.0.1 for D-link) and just did a “release” on my IP address. I did not renew it. This released the MAC address too. I then shut everything down and disconnected the D-link router and hooked up the new Linksys router.
That did the trick. I was trying that solution before shutting down and disconnecting the modem and waiting 2 hours for the MAC address to expire. This was a much faster solution. Fortunately for me, the D-link also releases the MAC address in addition to the IP address. I don’t know if other routers operate the same. Hope this helps someone else, because it was a real pain in the neck trying to figure it out.
