Great recap Akemi. I guess I am also a bit familiar with this stuff, however, since I haven't had to worry about "drivers" since moving to linux and not using BSD on the desktop for quite a few years now. I asked on NovaLug list first, since I had trouble posting to this list, and someone pointed out the ath5k driver. I couldn't remember the driver name, since I haven't had to for like five years, and their suggestion reminded me. So then I spent about thirty minutes trying to figure out how to install the centosplus kernel, and then went to bed. Then my post to this list provided the rest of the info. However, with aheros cards, you usually don't need to do too much research at the level you are suggesting, so that is why I saw the hash as not the relevant. You can probably find drivers for stuff that i have no idea about using your method, but from having to build wireless embedded routers on BSD, I remembered that for AR5xxx cards it was something like what was suggested on the NoVaLug list. So I already know what driver I needed, after I verified what card I had installed into the system. (Since I honestly hand't seen it in five years, due to it running in the wireless router that I built using BSD (which was running FreeBSD 7-stable, to date my references.) I think the last time I had to build a driver and worry about what version it was, could have been 2007. Lol... So thanks so much for your help with this. Now, if I could just find that pesky system-config-services gui.... LOL!!!!!!

Right, there is an important difference. That is, the 'lspci -nn' command shows the device ID pairing. In this case it is [168c:0013] for your atheros adapter. If you remember, I made a *guess* early on that the driver might be ath5k. I could have found this info easily had I known the device IDs. Using the ID pairing 168c and 0013, I would run this command on my c7 system: $ grep -i 168c /lib/modules/*/modules.alias | grep -i 0013 /lib/modules/3.10.0-123.8.1.el7.centos.plus.x86_64/modules.alias:alias pci:v0000168Cd00000013sv*sd*bc*sc*i* ath5k /lib/modules/3.16.1-1.el7.elrepo.x86_64/modules.alias:alias pci:v0000168Cd00000013sv*sd*bc*sc*i* ath5k This system has a CentOS kernel, CentOSPlus kernel and kernel-ml (from ELRepo). The output shows: (1) the device is supported by ath5k (2) ath5k is included in the centosplus kernel and kernel-ml but NOT in the centos distro kernel. Hope this info helps, Akemi _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
