My house has two separate co-axial cable connectors coming into the house, at opposite ends of the house. I have, at various times, used one or the other to connect my modem.
I'm wondering if I could use both connectors at the same time. I would have to buy another modem, of course, but having two modems at opposite ends of the house would mean that my wireless router wouldn't have to service the whole house. As it is, the wireless signal has to pass through plenty of walls and other obstacles.
I would use one modem for my HDTV and the other modem for my wireless router.
Is this a feasible setup? And is it legal...or would I have to pay Comcast for the use of another line? The two connectors seem to be part of the same line going from the street to my house because, as I mentioned, I have used one or the other at various times with no trouble.
I believe also that unless you use a router (hardwired or wireless) each modem will need their Mac Address put into the system. So if they do charge for an extra modem that would be when you can find out for sure.
Even if you could do it, I wouldn't. Rather then paying Comcast every month to have a second modem you could spend some money upfront. Look into wireless extenders. Netgear and Dlink sell them for less than $100. If you really want hardwired then look into ways to run ethernet cable from your router to your TV or whatever. Either way, I'd rather spend some time and money up front ONCE than have to pay a reoccuring fee.
There was one time I used a second modem. Was at a place where I rented a room. Comcast service provided. Ran the coax from to my room, and I did recieve the TV channels, which meant that the internet was there also.
Plugged in my router and my cable modem that I had bought when I had the service in my name prior to moving. When I tried to connect I kept getting that window saying to join comcast. FIgured it would not work. They did not even have my Mac for the modem in the system.
Tried for two days. Then an idea came to me. Never thought is woould work. What I did was change my DNS from Comcast dns servers to AT&T dns servers. And was I shocked. It actually worked and I was online. Never had any issues. One funny thing happened. My landlady lost her connection for like 5 hours. Me? I was hopping around the net as always and no issues.
I doubt that it would do that anymore. No reason for me to even try. But it is a true and funny story that did happen.
Not true nerdberg - you can have another modem. When I did it some time ago I was charged for the second Mac address. When you sign up for Internet service, the salesperson will also ask if you want to use more than one modem.
