For example that Mediacom access point. I can't tell what that is. If it's your shed or such then you should have power from your home to that shed and should try powerline networking.
Be aware you will not be able to talk them into installing your own gear there so my bet is you'll have a small shed or such to which they will install your connection and from there complete your last kilometer connection.
I have a home located 800' from the Mediacom access point at the road. They want to charge me $4000.00 to trench a line to my house. They won't hook up to a line I run myself. So, I'm going to have the install internet in my out building 40' from the pole. Then, hook up to a cable I have run myself. I can do fiber optic for less than $400.00. Cable and conduit. My brother has the end termination equipment, so that's covered.
Will I just need 2 converter boxes (one at each end) and use the Ethernet out of the modem and into the router, or is that just too simple?
