It's a little tricky but you can have your computer as close as possible to the connection box on the outside of the house,
then wire one cable pair to the modem, use the other pair to pass the signal to the regular telephone devices.
Almost every device hooked to the telephone line creates an impedence that degrades the connectivity. Surge protectors are notorious for this.
Unfortunately you are probably past the limit of V90 connectivity(3 miles of cable pair) or dsl would be available?
No. Try not. Do... or do not. There is no try.
