Ref reply no. 4 from Aquila, "What did I buy?"
It was a "wifi extender with marine omni antenna." This essentially was a small black box containing some electronics to amplify the received signal and with its own antenna for re-radiating it to the computer while the marine omni antenna was designed to receive the weak originally broadcast wifi signal and connect it to the aforementioned black box via a lead with a USB plug on the end.
Ref reply no 5 from Nigel, "Are you trying to connect with a PC or a mobile device?"
My intention was to connect via my iPad.
Note, prior to purchasing the wifi extender, I had on occasions been able to connect directly to the club house wifi from my iPad, but it was not very reliable. With the wifi extender I was never able to connect to the club house, and only once was I able to get it to connect to my home wifi while the system was at home.
As for the invoice, you can see from the attached photo what was charged. The VAT, which I did not query at the time of purchase, just does not relate to the subtotal on which it should !
Since getting my money back I've changed my mobile phone, and with the new tariff which includes two gig of data I can get all the internet access I need when within mobile phone coverage to enable me to check things like weather reports, emails etc.
