To whom it may concern,

I am having a problem with linux mint xfce version 4.8, it detects my internal wifi card but the card has no label for network manager. When I run the command mintwifi this is what comes up:

I. scanning WIFI PCI devices...

Also when I run iwconfig in the terminal this is what comes up:

lo no wireless extensions.

eth1 no wireless extensions.

What can I do to fix my issue? Your help is greatly appreciated.

I'm not familiar with Mint, but the output suggests that for some reason you don't have the wi-fi utilities installed. Do you have wireless-tools and Network Manager installed?

Update: Silly me. Didn't read the last lines of your post. Question: Does your wifi radio need some firmware? Check that.

do you have a module loaded for the card?
