My first question would be why you want to do this. cat 5 cable can be run 100 m without the need of amplification. and then all you need is a cheap switch and you could go another 100 m add another switch and you can go another 100 m.
in regards to if it would work im not sure. i dont believe so, you would need to be able to change config files on both modems to talk to each other and most of the time these are pushed out from the cable companies.
Thanks for all the replies; 1st - it doesn't work; having picked up a couple of Motorola's and worked with them - no configuration possible without HW changes and being a SW guy I don't do that... These units appear to be designed to work in conjunction with a head end unit.
2nd - why do it? the only connection between one end of my place and the other is coax from the cable co. This was laid in before extensive reno's long ago and now it's a major job to run anything else. A Telus V1000H is wired directly to the PVR and so to the TV at one end of the house. But most PC's are far from this little nest of wires, so I have a wireless router at the other end of the house with DDWRT on it acting as a wireless bridge to the Telus box. This works well enough, but is subject to hiccups, as wireless tends to. Actually the quality isn't bad as I had Netflix streaming HD over it with no problem, even tho' it's just 802.11g.
Guess if I want a solid connection I will have to spring ~$200 for a pair of ET/Coax adapters, or somehow run wire outside. Sobeit.
