Public bug reported:
Recently I have been experiencing intermitted total packet loss over
wifi.
I've already been looking at another issue in which Bluetooth
coexistence seems to be causing controller hardware to crash - bug
1719210 - so I'm rather suspicious of the updated iwlwifi microcode that
is used by newer kernel versions.
Unfortunately, I don't have a good reproduction recipe, as the fault
doesn't seem to occur immediately after boot, nor is it an absolute
failure of connectivity - from a user perspective, it feels like, for
example, the website you are using is responding exceptionally slowly.
It is only on testing multiple remote sites, and finding that rebooting
into an earlier kernel fixes the issue, that it is apparent that it's a
local OS problem.
