Hi everyone - <br>I get an annoying message when ever I use Wifi on my<u> Centos 6, Lenovo ThinkPad (T61</u>). I think I asked about this earlier this year, or late in 2010. Laptop uses Gnome, but can dual boot to Windows XP. <br>
<br>I got my Wifi to work, but I am sure that I did many things that Daniel G. would not do. I got it to work by adding libraries and checking the internet forums.<br><br>This is what I get besides the black box that says: Kernel Crash has occurred.:<br>

I tried to install ath5k also<br><br>I know I took a shotgun approach to getting wireless working<br><br>I created a file "/etc/hostapd.conf"<br> file is cut and paste from < <a href="http://madwifi-project.org/wiki/UserDocs/UsersGuideExamples">http://madwifi-project.org/wiki/UserDocs/UsersGuideExamples</a> ><br>
Scroll downb to: "Single AP with hostapd on an Automatically Chosen Channel"<br> <br> I tried to run the " myprompt# wlanconfig ath create wlandev wifi0 wlanmode ap<br> ath0 " command but got error unrecognised <br>
<br>Wifii worked after reboot but with this Bug reported<br>this Bug report occurs from time to time when I use wifi (beyond first time, most times I use wifi I get the Kernel Crash report, but not every time I use a Wifi connection)<br>
<br>reproduce<br>-----<br>1. First time I was able to use wifi card -- but I also got this message about kernel module crash<br>2. Was able to connect to internet with wireless-- even though I got this message<br>3. Restart wireless after reboot??? should reproduce the crash message it, does sometimes usually within 15 minutes, but I haven't deliberately tried to reproduce this Bug.<br>
<br>should I just continue ignoring this message?<br>Ken Bernard<br><br>P.S. I am always planning to drop Rick's on CABAL Saturdays but I always seem to be too busy.<br><br><br><br><br><br>
