Thanks for the suggestions. The reason behind this is that a "non-techy" relative has had a Samsung Smart TV for about 3-4 years, but has never been able to use the 'Smart' services such as iPlayer, etc, as the TV asks for a dongle when trying to set up an Internet connection, so she has never bothered going any further. MisterW's suggestion of a WiFi range extender would be a cheaper option than a Samsung dongle, but it would mean a trip up to London for me to set it up for her, as she wouldn't have a clue. Presumably, a dongle would just plug in and all she would need to do is enter her WiFi password, which I think she could manage, so that would be the preferred option.
