Bug description:
We were not able to completely pin-point the issue yet, so this is
more of a blanket bug for the current issues we are seeing. We don't
know where exactly the issue can be located.
While preparing and testing 18.04.4, certification reported issues
with our uc18 images on the pi4 with wifi ac tests. One of our
engineers (Brian) confirmed it locally with a wifi access point
restricted only to 802.11ac. After some additional testing, he noticed
that he had the same unreliable symptoms for both the classic and core
images, as well as the 19.10.1 classic images. The symptoms seem to
vary, from inability to detect 802.11ac APs, inability to connect
and/or receive an IP address and no traffic getting through.
We will provide all the information that we have. Raspbian works
better in this regard. We have pulled in the wifi firmware bits from
Raspbian and using those, and that seems to resolve all flakiness.
