Does anyone know how to get the wifi indicator working on the Acer

suddenly, an hour or so ago, I saw the signal bars drop from 4 to 1.
Then I lost the connection.

Nothing has changed, in terms of location or additional equipment in
the room, and attempting to re-start the connection tells me that it
has been disconnected. I've tried fiddling with that switch again,
but there is no way of knowing whether it is active or not.

<sigh> I hate mysteries. This morning the netbook connected to the
wireless router at bootup. I've still no idea what went wrong
yesterday, or why I couldn't scan for a connection. It's as though
something turns wifi off and it can't be turned back one.

Personally I think it's another form of rsibreak :-)

As we all use computers here, we could all occasionally benefit from an
rsi time out. :}

Assuming you shut the machine down last night after the net stopped
working, _perhaps_ it would be useful keep track of what the
room/computer temperature and uptime is each time it stops working
(from a cold boot) ... It could be that a component is getting hot, or
saturated in another way that has a hysteresis curve.

Room temperature is not likely to be a problem - it wouldn't have varied
more than 1'C all day. However, I will be keeping an eye on uptime -
thanks for the reminder about that one.

Did you also shutdown the router last night too?

No, the router is 24/7, and gets a reboot maybe 6 times/year.

Have you done anything to see if someone else may be attempting to
use/abuse your router, like look at it's recent IDS logs?

The router mails me with reports of unusual activity. Nothing has shown
up there, although I've had the routine daily report. Again, due to
physical location, this is unlikely to be the problem (and this laptop
continued to work with the router the whole of the time).

Might try transferring a couple of fedora install DVD isos across it
into /dev/null, or some other throw away storage on the machine, to see
if it can only handle so many bits before needing reset.

Just ideas.

And all worth considering. Also, an off-list message suggested to me
that I should keep an eye on whether it coincided with meal-preparation
times, due to microwave oven usage. Again, this laptop has never
suffered from that, but I haven't ruled it out.

If I find any evidence to even suggest a likely explanation I'll report
back.

The connection is lost again - at approximately the same time as yesterday.
This time I can say for certain that microwave oven activity is not the
cause.

Most of the day I have seen a 90% strength connection. As 8 hours uptime
approached it suddenly dropped to 14%. I carried on working, including
downloading and installing an rpm, for about half an hour. Then I went for
my daily half-hour walk. When I came back the connection was lost and it
could not connect again. The symptoms are identical to yesterday.

Using system-config-services I saw that netfs was marked as dead. That
suggested to me that it should be running, so I started it. netplugd is
marked as disabled but running, as is network. To be on the safe side I
restarted both. I also restarted NetworkManager. I'd appreciate comments
and guidance on these and any other services that could be implicated.

I am now going to power down the netbook and leave it until after dinner.
I'll power it up again in about 1.5 hours. If it connects then I will
suspect a component heat problem, although I can feel no heat worth calling
from the case.

Lots more testing went on. I now have good log output which I've attached to
https://bugzilla.redhat.com/show_bug.cgi?id=472248 Meanwhile, my logwatch
report has come in. Could these entries have any bearing?

kdm: :0: PAM adding faulty module: /lib/security/pam_gnome_keyring.so: 6
Time(s)
kdm: :0: PAM unable to dlopen(/lib/security/pam_gnome_keyring.so):
/lib/security/pam_gnome_keyring.so: cannot open shared object file: No such
file or directory: 6 Time(s)

Certainly gnome-keyring is used by NetworkManager. If it's likely to be
involved, I'll add this output to the bug report.
