A:AnswerThis product will work with most cable internet providers. Windstream is not a cable provider - their solutions are DSL or fiber. This modem is not compatible with Windstream.
A:AnswerNo, this modem has no phone jack (like some ISP provided modems/gateways.) There are only two 1Gbps ethernet ports, the coaxial cable port and a power input.
A:AnswerThat depends on your service area. Check the website for your area or call their number and ask. The key word you ar looking for is Docsis 3 or Docsis 3.1,
A:AnswerI paired mine with a Netgear Nighthawk RAX43. It works great with no issues. I have 1gb service through Sparklight and I'm typically pulling 826mb download and 52mb upload through the wifi 5g band. Depending how far the extender is, you may not get great speeds through that device. I have a repeater in my garage and it's pretty far from the router and only puts out about 10mb download and 10-20 mb upload. But that's really no fault of the modem and router, just realize the speed may bottleneck there. Hope that helps.
