I'm guessing this is specific to my hardware platform, or you would have been
inundated with reports by now. Dell Studio 1537 laptop. Core 2 Duo, AMD
WiFi has been really flakey for at least the 12.x series. In the past, I've had
it drop out and stop communicating with the router, then attempt to reconnect,
and get stuck and fail. This I think was due to weak signal strength.
Presently, the major symptoms are as follows. I connect to a router, use it
successfully for a while, then I suspend to RAM. After waking up, the network
has disconnected, and it gets stuck on reconnection. It hangs on either
"configuring interface" or "authenticating", as reported by the
in the system tray. Sometimes this happens after a suspend to disc, but I think
it's less frequent.
My work-around is to, firstly, toggle the hardware WiFi enable to off, then a
few seconds later back to on. This may allow the Network Manager to connect, or
it may take a few more goes.
Sometimes I have to suspend to RAM and wake it up again, before this will work.
This may or may not be related, but X sometimes gets very slow after
suspending, and consumes a lot of CPU. Suspending again doesn't seem to fix it,
I have to reboot. I also get a lot of hangs where KDE/Plasma stop responding,
and sometimes they don't come back so that I have to kill my session and lose
my work. I tend to blame the proprietary AMD drivers, which are of grossly
substandard quality (and everybody knows it).
I suggest that the way to reproduce this is to get access to any of the Dell
Studio 15 series and install openSUSE. I have reinstalled several times, as
part of version upgrades and the like, and it happens with every installation.
Again, it may require ATI drivers.
Steps to Reproduce:
1. Acquire Dell Studio 15
2. Install openSUSE 12.2
3. Connect to WiFi, suspend to RAM
