Created attachment 497660 [details] output of dmesg Description of problem: For no apparent reason my Wi-Fi connection went down. I have a D-Link DWL-G122 C1 USB dongle. The lights on it went dark. Looking into dmesg, I spotted this: [19488.088875] npviewer.bin[3441]: segfault at 0 ip 000000004f6d32b0 sp 00000000fff65a70 error 4 in libglib-2.0.so.0.2800.6[4f692000+118000] taking the USB dongle out and plugging it back in brought the connection back online. I have no idea what caused this and how to reproduce it. Also, Abrt shows nothing regarded to the crash and I have no idea where Fedora does store coredumps. So please could you tell me that? (And what to do with it?) My HW profile: http://smolt.fedoraproject.org/show?uuid=pub_56adb9dd-c210-4a9d-870e-6ebef7f8d37a + D-Link DWL-G122 C1 USB dongle
As I understand the problem, this is related to nspluginwrapper, so probably produced by a browser plugin. IIRC nspluginwrapper is blacklisted from abrt because it will take crash of proprietary plugins. The crash was propagated to NetworkManager because it's using a glib2 loop. So here are some components that might be involved: -nspluginwrapper -glib2 -NetworkManager-glib Please re-assign to one of the component above. But please try to reproduce the problem.
I don't think a crash in nspluginwrapper (And I suppose inside flash plugin) can bring the wifi down. Closing for now, please reopen if you have closer info or reproduction steps.
