Thank you Tim for sorting the WiFi that kept dropping out. Tim spent ages scratching his head as to what was going wrong, then found a good solution that has worked ever since. It's a dongle, sitting in one of the USB ports and means that I don't have to plug in my work-around ethernet cable any more. Neither have I spent ages twiddling my thumbs waiting for the WiFi to return as mysteriously as it vanished. Nice work! 5 stars. Heartily recommended.
