[svlug] using Comcast modem and a Linksys router?

[Tom Melendez]

Not sure of the solution, but some thoughts:
Hi Christian,

- You already tried powering down the modem, imagine.  With a cable
modem, you generally have to power it off and on for it to recognize a
new MAC address.
- Comcast does DSL?  Didn't know that or is that a typo?
- Is the modem itself a router?  Some DSL modems are.
- some DSL modems actually have a web server/configuration utility
built in (even if they are not routers).  What kind of modem is it
(make and model) and can you get into this utility?
- what kind of router do you have?  If you plug in the modem to the
WAN port and connect a box to the router, with the router's config
utility you can see if it is pulling an IP address from the modem.
