Thank you for such a prompt & helpful response. Problem solved by installing the linux firmware deb as advised.
Because Bodhi has remastersys it should be quite easy to roll my own functional live disc.
Side note: I hope you will include this package in the default install. An issue that requires the net to fix, when it is the net access that is broken, is a real headache.
Also, I know purists would say we should all be running free hardware. However, lots of us are running on second hand gear out of financial necessity, we do not have the luxury of running out & buying what we would like and are the hardest hit by an issue like this.
