Hi,<br><br>I've been using centos6.2 for about 6 months now and have been running it ok on a Sony Vaio. I recently got my hands on a new laptop and installed centos6.2 on there. It's a relatively new machine (Samsung NP700) so I anticipated there might be a few compatibility issues. The main issue was that my wireless card was not recognised. After a fair bit of researching, I came across the kmod-compat-wireless fix.<br>
<br>I installed this (yum install...) and it completed with some errors, but I now have wireless connectivity. My question is I'm not sure if should be worried about the warnings I got after installing kmod-compat? Afterall, I now have wireless...<br>

Done.<br><br>Installed:<br> kmod-compat-wireless.x86_64 0:3.3-2.n.el6.elrepo</i></font></div><br><br>I know there are later versions (3.5-rc3xxx) of kmod-compat-wireless from <a href="http://linuxwireless.org">linuxwireless.org</a> but the procedure for using those seems a little complex - I'm still relatively new to linux :-)<br>
<br>Can these warnings be safely ignored or should I be taking more active steps to resolve them?<br><br>Thanks,<br><br>J<br>
