Bizarre goings on today!
My router decided to reset itself to factory settings today. I was not browsing at the time, PC was on and the WiFi settings disconnected.
Connected again OK then a few minutes later disconnected and two new entries in my WiFi list called Billion2.4 & Billion 5.0 so I knew it was my router. Just re-entered the details and I'm connected again.
Anyone else experienced this? Glitch or hack?
