= Troubleshooting Installation =
 
== Modules Not Found ==

If after make installing, and doing modprobe ath_pci you get a “module not found” error, you may need to copy the modules to the correct location in {{{/lib/modules}}}. For example, if you are running a 2.6.11-1-686 kernel, you may need to copy the directory {{{/lib/modules/2.6.11/net}}} to {{{/lib/modules/2.6.11-1-686/net}}} and then run
{{{
depmod -ae
}}}
(This problem only occurs when you compile kernels the Debian way with {{{--append-to-version}}}.)

== rename_netif ==

If after installing and rebooting/modprobing an error like the following appears:
{{{
udevd-event[7118]: rename_netif: error changing net interface name wifi0_rename to ath0: Device or resource busy
}}}
It means that persistent network interface renaming is being painful.

Take a look to see if '''/etc/udev/rules.d/z25_persistent-net.rules''' exists. If it does exist, and it contains a line similar to:
{{{
ACTION=="add", SUBSYSTEM=="net", SYSFS{address}=="00:11:22:33:44:55", NAME="ath0", ENV{INTERFACE_OLD}="$kernel"
}}}
Comment the line out and reboot.
