Do you have “Century Link” phone service in your area? If you do give them a call. They give outstanding service and “speed” I understand even for dial up.
I'm about 8 miles wire wise to the phone company. There is only one way I can get Internet via phone lines and it is very expensive. It would involve a four wire data circuit. Those must be perfectly balanced from Central Office to modem.
I'm about a half mile from The SLICK cabinet that helps somewhat. To obtain DSL type speeds I think three miles from the central office is about it unless they have the necessary repeating system like fiber optics.
I'm on a buried hard wire cable all the way back to the C.O. Comcast stops a half mile away and where I am at on the back of a dead in road a quarter mile long with only about 4 residents it's not going to happen. Not even wireless broadband service from ones like from Verizon is possible here. I have to stand on my head to make a cell call in the house LOL.
But I did just check Century Link's site. Nope.
