LG - thank you for that. This
thread shows how I sorted it out with bnt's help, and 'discovered' I had the very thing I needed on the mobo

, just lacked the drivers. Talk about 'limited' tech info on the Mobo - a large sheet of paper folded into A4 size was all I got, and no mention of downloading the drivers. Nothing obvious on the CDRom or the web either.
As you will see the new 'connection manager' part of the download knackered ALL connections but when un-installed it was fine.
