Re: [help] 851W and ISP DHCP

I highly doubt that the MAC cloning will solve the problem.

The 851W will be the 4th router that I have used with this connection (only used one at a time)

Verizon supplied an Actiontec MI424-WR router that I am currently using. I have also gotten 2 seperate Linksys routers to pick up an IP from Verizon.

The 851W is the only one that will not get an IP from Verizon. (I never colned MAC addresses on any of the other routers)

OK, I'm totally in shock, but when I cloned the MAC of my Actiontec router, the 851W got assigned an IP! It's so strange because I never cloned the MAC address on either of the Linksys routers I tried.

Now it seems that the 851W is a bit slow on my connection. When I ran a speed test, I only got about 8Mb/s from my 15Mb/s connection. Any suggestions on how to improve that?

Aha! So your ISP (Verizon?) does lock down your WAN router interface MAC address ....

The Linksys router was probably running some non-compliance RFC code that could somehow "go around" the MAC address lock down. Typically consumer-grade routers like Linksys are behaving so.

Well, at least now you can connect using your 851W router even you feel it is slow. One thing I can think of is the application inspection. When you notice, your router inspects a lot of application traffic; especially those that are running over HTTP like IM. If you like to experiment, you can try to remove the inspection and see if your connection is running faster.

Thanks for the help.

I was amazed when it worked, but I was glad I followed your suggestion!

I'll work on taking out the application inspection. I put a fair amount of stuff in there that I probably will never use. I kind of want the paranoid route to start with.
