We are using a internet provider modem ( Sagemcom F@ST 1704) that is located on the ground floor of a old farm house. The signal strength can range for good to poor downstairs when using a laptop. Upstairs my son's PC signal the signal is usually poor or goes out all together. W have looked at home plugs, extenders and such but are confused as to what might work in our situation. Another way to go would to buy a different modem, but we would rather not spend a lot of money. Any suggestions would be appreciated.
