Red Hat Bugzilla – Bug 626266
WiFi network stops working at random
Last modified: 2011-01-14 10:10:18 EST
Description of problem:
The WiFi net goes down at random, ifconfig shows the wlan0 interface up (with IP address and all), but ping to the AP says "host unreachable". Have to rmmod iwlagn and restart the network:
iwconfig wlan0 essid xxxx
(NetworkManager is currently totally hosed).
08:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)
Version-Release number of selected component (if applicable):
Happens at random, seems o take a couple of hours of normal use (update rawhide, look at a some webpages, get email via fetchmail, get updates via git and compile the results for a few programs) on average
Steps to Reproduce:
1. Absolutely no clue, sorry
ifconfig wlan0 shows interface up, IP assigned; ping 192.168.1.1 (AP) says "host unreachable". Have to remove and reinsert module, restart networking from scratch.
Could we see the output of dmesg immediately after the failure?
Hasn't happened again. Will remember this.

Boot log for kernel-2.6.36-0.30.rc6.git0.fc15.x86_64 (broken)
Again broken. I just confirmed kernel-2.6.36-0.30.rc6.git0.bz637647.fc15.x86_64 does work (running that one right now).
Sorry about that, wrong bug :-(
Presuming comment 4 cancels comment 3...is this still a problem with currently updated Fedora kernels?
This hasn't happened again since around August. Better close.
Closing on basis of comment 6...
