error while starting the wpa supplicant

Thu Sep 13 05:55:53 PDT 2007

Hi Saurav,

I have also faced the same issue. In this case, there is a AP in eth1 and STA is set at eth2 on the same card. Cannot it associate over VAP network? i mean between different interfaces within same card?
Are there any settings within .conf file or .config that is missing?

Thanks
PPN

There is nothing wrong with the behavior.
As I see it, there are no APs in the vicinity.
Without running wpa_supplicant try running following two commands.

Ifconfig eth2 up
Iwlist ath0 scan

I think you will get "no scan results".
If so, then there are no APs so that your sta vap would try and
associate to.

Because of the above reason the state changes from scanning -> inactive
after timeout happens.

BTW which security (wep/wpa/wpa2) you want to implement using
wpa_supplicant.
And also you need Hostapd to do so.
