Motorola SB6141

I'm not aware of plans to add it at this point, but our list of compatible modems does tend to grow over time.  We do have several other d3 modems on our list.  You may already have the link to our approved modem list but if not I've included it below.

Thanks

I have one that worked great with Time Warner Cable in Wisconsin.

Cox Support tried it as a 6121 and 6180. Got great signal to modem, but couldn't get to router or to direct plugin to XBox.

Forums suggest Zoom 5341J but Zooms have died on me before :(
