[Bug 852190] Re: 7392:7811 Edimax EW-7811Un USB dongle won't connect to networks (rtl8192cu module)

 

After three years, I think people can judge for themselves who is being
rude and especially who is being obnoxious.

Personally, I consider it pretty rude to make people do silly busywork
and jump through hoops simply for the sake of protocol without EVER
making any real progress.  Being rude in words is not OK.  Being rude in
action is much worse in my book.

That being said, I think it is clear that this ticket needs to be
addressed upstream.  It should be pretty clear by now that Canonical
won't expend any effort to fix this and kernel work seems not to be an
area of Ubuntu community effort.
