The computer shop's technowizzard was puzzled when I took the laptop back after he'd sorted it. He'd installed the new drivers and it appeared to work so why, when I got it home, did it not work? I was even more puzzled when he tried it in the shop and it worked perfectly. "So it must be at your end" he said with incontrovertible logic.
So back to the drawing board and the other technowizard who supplies our micro-wave broadband and wifi router. In the late evening I received a call from him. "Ah. The level of security on your router must be too high for Windows 7" (all the other machines we use are Macs or pre-Windows 7) "I'll just alter it." Which he did from his desk at home and then managed to puzzle Wendy up at The House by re-setting that router too. She had been quietly using Martin's laptop when the wifi stopped working. So I popped up and gave her the good news and then spent a couple of very pleasant hours setting the new laptop up with various programs and virus protection with a glass of Scotch perched at my side. I've never been a spirit drinker (gin doesn't count) until fairly recently and now, after 40 years in Scotland, I'm suddenly finding in New Zealand that Scotch isn't such a bad drink after all. I arrived back at The Cottage somewhere before midnight with a great feeling of satisfaction.
