Re: WiFi coverage
He is next door to Harrods and on a residential(ish) street with a *lot* of APs nearby. At least one of those will be running WEP or have a PSK of "Password1" or "hanscrescent" or something equally stupid. If he does not have internet access, then I'd be quite surprised.
He's here (Google Maps, Street View) That droopy flag is Ecuadorean and those green boxes to the right of the iron railings are BT jobbies. Yes he has the internet rather close by.
