Alternatives: DSL, but only if you are within about 1500 feet from the DSLAM, the electronic box that provides DSL to your area. If you are farther than that, your service will not be what they advertise. The 30 day free trial would give you the information you need; if it's fast, you are close. Frontier will never tell you the location of a DSLAM. Before you sign up, though,there is a faster way to learn about DSLL. Ask your neighbors how their DSL service works. If they are fast, you will be too.
Satellite is not a viable option for high speed Internet service.
FIOS is a great product and Verizon/Frontier is working hard to deploy it. It is incredibly expensive for them to provision residential neighborhoods. During the housing boom, they were focusing on new developments. They didn't focus on established neighborhoods, apparently because they felt it would be too difficult to supplant the existing services. In new developments, they could sign exclusive deals. When building of new homes slowed to a trickle, so did the emphaisis on spreading FIOS. So if there isn't FIOS where you are now, don't hold your breath.
Since Verizon is the incumbent phone company, your won't see ATT U-Verse there as it's not their territory in which to build. U-Verse is facing similar problems that FIOS is facing anyway.
Before you commit to a new DSL service, you may want to speak with some of your neighbors. Do they use TWC? Have the experienced the same issues? If several neighbors are having the same issue with TWC, you can get their attention by having everyone call with the same complaint, and have them all cite the other addresses where the problem is happening. Don't talk to the overseas folks, insist on speaking to someone relevant. Alternately, when you get to their automated answering system, push "Disconnect service," which will put you in touch with the escalation folks, who usually are local, competent and actually care that you are having issues.
