Marc - I don't know what kind of comcast modom I have - I don't see any lable on it...Here is some info from a friend whose husband is an engineer:
--------------------------------------------------------------------------------
Re whether it was the modem creating the problem in your DSL experience, and dial up vs. DSL modems: Peter said that different modems may have different shieldings. If a modem has wifi capability, it might actually be broadcasting the wifi even if you are not hooked up to it. Might be something to check out. He said it is a high-frequency signal; 2.4 Gigaherz: About like a handheld phone (not a cell phone but a portable wirefree handset). However, the power of this signal drops rapidly with distance.
He does not know how the Comcast DSL would be set up, but if it is like ours, then there is a modem box connected to the primary DSL line connected to one computer, than the 2nd computer (I am assuming you have 2 computers) runs off the one modem via (in our case) cable. He suggests that if the modem box ends up in your space, (sometimes all this has to do with where your comcast connection is, where the computers are) then put it across the room and run a cable from it to your computer.
I got out the EMF meter we had and measured the modem which sits about 2 feet from my head on a bookshelf. It had no discernable output, but I know the EMF doesn't measure everything.
However the cable did have a high magnetic reading. Perhaps that is why my eyes have been so sore recently. On the other hand, maybe that is due to all the computer gaming. Oh well. I basically don't spend more than a half-hour or so 2-3 times a week on the computer-- that is all I can take. I don't mind some negative effects, because of the usefulness of it for email and research. Besides, if I sit back 2-1/2 - 3 feet from the computer and its cables, the intensity of the field drops back down to zero. Distance is everything.

He said the reason why you reacted badly to the DSL before is that the standard DSL cable is not shielded. However, the Comcast cable that brings the DSL signal is both shielded and grounded. He said if you have Comcast, you are already getting the DSL signal-- it comes along with everything else, it's just that you do not yet have access to it. If you can tolerate Comcast, you can tolerate the DSL because it is already there. He said that the Comcast cable is a coaxial cable, meaning the central wire that carries all the info, all the current, is inside two braided insulating, shielding cables--nothing can leak out. The cables ground themselves through the metal of the attatchment to the TV.
He said that what might be a trouble is if you have 2 computers, and if the connection inside the house, after the signal has reached your TV, is then over a wireless (wi-fi) network, to reach the computers. If so, then something would be broadcasting through your house that might raise the EMF exposure. (Starbucks and many other places have wi-fi-- you could test your tolerance there.)
We recently added DSL via our phone line, and Peter installed cables (having to go underneath the house and drill holes to run them) to connect our 2 computers. My understanding is that in general, there is always the option between wi-fi and cable. Many people do not like wi-fi as it is not secure privacy-wise.
