Please:

1. Edit the report description, so it explains which steps you followed to recreate the bug and which are the consequences of it.
2. Set this report status back to "confirmed".

aljosa, thank you for reporting this and helping make Ubuntu better.

To clarify, do you actually have a usability issue with the WiFi?

[penalvch (penalvch)]

aljosa, as per your direct email, it appears you may be having two distinct issues:
1) Innocuous messages about firmware not loading (this report).
2) WiFi functioning correctly 80% of the time.

Regarding 2) feel free to file a new report about that scoped to the potential functionality issue.
