If you see an FRP repairman/repairwoman, ask them to check. It's been done on our road. One of my neighbors who is on VPN with his employer, did after being frustrated with not getting correct info from the FRP Maine offices, who check with the engineers, on what is supposed to be available.
I was the neighbor getting much higher speeds than my neighbor down the road from my neighbor. I'm closer to the CO.
I now use Time Warner @ 50 Mbps with no data cap. I, actually, even dropped FRP for phone, using Voice-over-IP from the cable box. Caveat: if you buy a cable box, same box as your ISP, the phone piece is proprietary and the phone will not work. Also, if you lose power, and if you don't use the battery back-up in the cable box, you don't have phone service. Cell phones negate that problem, however.
I'm also a potential "cable Cutter", a mentioned by another forum member. The DVR is an issue that I wasn't happy with ... yet.
Maybe Gfast will come along faster than expected.
