Question ID: 758158
I am looking to add an additional cable modem to my Time Warner
Roadrunner service and am asking for advice if it's possible to
install two cable modems on one RoadRunner connection?

I called Time Warner and they said I have to buy a new modem with
roadrunner service for $45/month. That is unacceptable.

Here's my setup: I have my cable modem setup in my livingroom next to
the TV. Now I need connectivity in my home office and somehow a
wireless  connection won't reach it. So I paid $30 for Time Warner to
run an additional wire to my home office and they installed my cable
modem there. Now, I would like to also have a modem next to the TV
(for gaming, VoIp phone etc.).

Could I just buy a third party cable modem (such as a Motorola
Surfboard SB5120) and attach it to my connection in the home office?

I heard that I could attach a third party modem but need to call in to
Time Warner to have them authorize the MAC address. Does any one have
experience with that? 
Many Thanks

Hello florianpeter-ga,

Have you thought of going the router route (with wires)? You are
correct that they would have to authorize the device, and they
wouldn't do it without having you pay more (unless you got really
lucky with getting someone on the phone who doesn't care either way).

Hi Tisme,

a "router with wires solution" would be annoying since the time warner
cable is already going all the way through the whole apartment into
the home office. I'd have  to double that with an ethernet wire.

I guess my question is a bit redundant, since as you say it's pretty
much up to the Time Warner rep to be lenient about it and just
authorize a second MAC address  .

I was hoping for some hacker solution that fakes a MAC address or a
tip about buying a second hand time warner modem that is "authorized"
or something to that degree...

Hello florianpeter-ga,

Even with faking it, only one device at a time would work. Maybe look
into getting a stronger wireless network (there are relay devices
available). Let me know if you want more information on this.

yes, I guess the wireless option is the way to go.

I did buy the Linksys Wireless-G Broadband Router with RangeBooster
(WRT54GR) but that didn't reach over to the home office either.

I tried using an Airport Express to act as an "extender" but the setup
was a bit weired and ended up not working.

Can you recommend another type of relay device and solution that you
would recommend.

Post that as an answer and I'll get you paid ;-)

Hello florianpeter-ga,

I recommend the Linksys Wireless-G Range Expander Router Wireless
Signal Booster for your situation.

Don't worry about the bad reviews, most of them are from people
without Linksys routers. If you have a Linksys router (as you
mentioned), it works wonderfully. I have personally set one of these
up for a friend and it works great.

Let me know if you need any clarification and I will do my best to
further assist you.

All the best,
