I mangled my wireless interface.

[supertight]

I'm not sure what I did. I have the wpa_supllicant and the ifcfg-wlan0 file both configured.
When I try to launch it with $ ifup wlan0, I get the following error:

Code: Select all

ERROR     : [/etc/sysconfig/network-scripts/ifup-eth] Device eth0 has different MAC address than expected, ignoring.

I don't know why it's trying to access eth0.... I messed up a sim link?

Any help would be awesome. Thank you.
