I've been using F8 on my "main" laptop since January and have F8 running
on a total of 4 systems (2 of them laptops). F8 is up to date on the
"main" laptop and I just accessed my home network (WEP) and office
network (WPA) on Wednesday. NM has been working OK since I installed F8.
Starting yesterday, I cannot connect to either network. I've noticed
that NetworkManagerDispatcher (usually visible under services) is gone
(NetworkManager is still there). I'm also getting an SELinux warning
message about NetworkManager (never had one before). When I do:
[root@localhost ~]# iwlist wlan0 scan
wlan0 No scan results
as root, it says "No scan results" even though there are a bunch of
networks available. This used to work and show me what networks are
available. The other laptop has not been updated in a couple of weeks
BUT NM etc. all work fine - I have no problem connecting to the networks
using it.
I'm using the "main" laptop now but I'm connected via a wired ethernet
connection.
[root@localhost ~]# uname -r

I'm using a BCM4318 (it's been working OK for 3 years). It shows up as
usual in the network config gui.

Any ideas on what has gone wrong? I'm stumped.

P.S. Here is the SELinux info
Summary:
SELinux is preventing NetworkManager (NetworkManager_t) "setsched" to
<Unknown>
(NetworkManager_t).
Detailed Description:
SELinux denied access requested by NetworkManager. It is not expected
that this
access is required by NetworkManager and this access may signal an
intrusion
attempt. It is also possible that the specific version or configuration
of the
application is causing it to require additional access.
Allowing Access:
You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can
disable
SELinux protection altogether. Disabling SELinux protection is not
recommended.
Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
