Andrew,
Yes, multiple disasters. Having fiddled around in console with 'startadsl' I then had to put all same info again into control centre network conns. It then worked OK but a bit slow. I downloaded som updates from Mandriva, compiler updates I think. I also downloaded AVG free and installed it- though now I can't find AVG to turn it on!  Next I disconnected and now it won't reconnect. If I run startadsl I got message about dma then message ioctrl. I just tried it again and it tells me eagle-usb driver not loaded! I might sling it all in the bin and buy two tin cans and a piece of string.
