I looked at these before and tried to compare them when running the verizon dsl network.
Hopefully you can see problems.

The MTU is 1500 -see ifconfig above. Is that OK? It is the same as on the Verizon set-up

I don't think I do - and I don't know how to do it. Wouldn't the IP change on a DHCP boot? Thanks for the input. Sorry if I am a little dumb about this stuff.

I did a lsmod and saw nothing about ppoe, I also did a search of /var/log/messages for ppoe with no results. Is there somewhere else I should look?

I think I will Fight On here for a while. I don't know anything about
routers, and I guess it would cost money. Maybe later. Thank you for the input.

Another thing that is baffling to me is that Google Earth works fine. I looked at tokyo, which I am sure I never did before, to avoid a cacheed answer. It worked fine and the modem lights were real busy.
You guys are great.
