so, after getting jaunty to work like a charm, I decide to revert to Heron to experiment with the drivers for my ancient radeon 9800 graphics card.

installation goes without a hitch, and I have the (iBurst - South Africa)usb wireless modem chugging along merrily by running the drivers from sourceforge and dialler from roaringpenguin.

and then the fun started. after running the vast amounts of system updates, my internet connection dies a miserable death. reinstalling the drivers and trawling forums has thus far not netted a solution.

can anyone guide this illiterate (dangerous power user, but clueless when it gets to command-line) user to the source of the frustration?
