True story… the managing partner of a regional firm had broadband installed at their home so they could run a home-office from there. And, as part of the setup, there was a home wifi link. Nothing unusual there except the partner could never manage to log onto the wifi.
The firm sent along someone from the IT department and the wifi worked for them. But, the next day, the same complaint from the partner. The complaint was escalated and the broadband provider sent along someone and the wifi also worked for them. But, the next day, the same complaint from the partner. Eventually someone sat down with the partner and went through the logon process with them. That was when the problem was finally identified – the partner had been trying to logon on to their next-door-neighbour’s secure wifi network.
