Now this may be because the sierra module in zeroshell is version 1.2, and the sierra linux recommended module is now version 1.7. The sierra module is supplied as source code by sierra, and needs to be compiled against the running kernel.
Are there instructions anywhere on how to set zeroshell up as as a dev environment, so I can do the required compile, then make the modules available to the greater community
Generally in the forum there are several threads describing the compile process. Unfortunately I haven’t done it so I can’t help you on that. Do a search first and if you are still in trouble you can ask a more specific question.
