Have just tested Forky (Debian) release on both the 2A and the 2F, and in both cases the wireless driver survived an upgrade. I also tested the Plucky release on the 2A, and the wireless driver did not survive the stock upgrade. I have not tested the Plucky version on the 2F yet. Also it should be noted that the cron implementation in the Forky version for the 2A is fouled up. Any ordinary user's crontab has to be edited by root. Bad permissions on a number of files. Nice to know that at least the wireless adapter problem has attracted someone's interest.
