That’s the entry we’re looking for. You should have an eth1 device created:

/sbin/ifconfig

That is the wireless device. Now use network manager to configure.

13

I did all that. still not connected. My router is hidden. I scanned found bunch of neighbor wireless. Any more suggestions.

14

I got it to work by unhide my router. Its connected to internet. Very odd.

15

So its all good now?

16

thank you.

Welcome

I see that you are allready going now. Fine. But next time please look around a little bit before you post. This saves your and our time.

I have a question about this. Is it normal for a wireless adapter to show up as a ethx device and not a wlanx device when you run ifconfig?

19

The device is determined by the driver. Intel wireless drivers use eth* naming. A udev rule can be used to add a desired alias if required:

For example:

FWIW, my Broadcom Corporation BCM4321 wireless device (using wl) driver uses the eth* naming as well.
