Much has been written about the comcast changeover, but because it is
so fragemented, I'm still a bit puzzled.

I have a working setup to @home with a Linksys and 2 PCs. The router,
the cable modem and the 2 NICs each have unique MAC addresses.

The router gets its WAN IP address dynamically; the LAN address is
192.168..x.x It has a host name and a domain name entered in the setup
page.

Is there some compelling reason why I have to change change the WAN
MAC address of this router? If so, what is it?

Someone told me that all I had to do was:
1. delete the host and domain names
2. power down the modem, router and PCs
3. power up the modem, router and PCs
4. check the router setup

Is that true? If not, please tell me what to do to make this work.

Incidentally, I got mail from comcast saying that my email username
would not change, but when I sent email to "username"@comcast.net, it
bounced. Que pasa??

Thanks.

I have same setup at home and have to make same transition to
comcast.net in next month or so. When you have it working, PLEASE post
a summary of how you got it working to the newsgroup and/or email it to
me at kevin...@home.com. No idea on your bounced email msg.

Where are you located?

I'm sure it will appear here.

Do you have kevin...@comcast.net as your email address?
Does it work? Do you have the same password?

Thanks.

I have a Linksys router and 3 PC's. Comcast stopped working today (Michigan
user) and here is what I did to fix it.

Go to the PC that they installed your cable modem into and get the MAC
address of the NIC card. (Win 2000 go to Start - Run - "CMD". when at the
DOS prompt type in "IPCONFIG/ALL". For Win 98 go to "Run" and type in
"winipcfg". Write down the Physical Address of the adapter. Should look like
"xx-xx-xx-xx-xx-xx" with letter and numbers. Then log into the router setup
(see your router for instructions). For the Host name leave your Comcast
assigned name in this field (looks like: cc-xxxxxxx-A). Leave @home.com in
the Domain name. Make sure "Connect on Demand" is checked on with a 5 Min.
Max Idle time at the bottom of this page. Go to DHCP tab and make sure it is
enabled with at least as many users as pc's on your lan.

Now go to the Advanced tab - Mac Address Clone and enter in the MAC address
of the adapter you wrote down from ipconfig.

Click on apply then turn off your pc, unplug your cable modem and router for
at least a minute. Then turn on the cable modem first, wait till all lights
are on steady then plug in your router and then turn on your PC. If this
does not work, contact Linksys directly. They have great customer service
and are familiar with all of the configuration issues from the highspeed
ISP's including Comcast.

Hope this helps.

Haven't attempted to use this address yet. I have not yet received any
instructions from Comcast.net on how to implement the transition
(planned for late Feb I think).

Thanks, Pat. May I ask some questions?

Why? These are @home values?

Why is this MAC cloning necessary?

I did contact Linksys but haven't heard anything from them yet.
