Hi everybody.
I have a question.
Wireless worked fine, I use kde and networkmanagement.

Now I have updated the kernel to 3.8.13 stable.
Same config (compiled with make oldconfig).

networkmanagement doesn't see my wireless anymore.
Unless I install deprecated wireless-tool and perform a
Code:
iwlist scanning
.

what's happened?

a couple of reports recently that networkmanager problems were corrected by changing to newer or regressing to older versions.

does /var/log/messages?

No luck.
Only the command
Code:
iwlist scan
finds the network.
Networkmanager what command is suppose to use to scan networks???
Code:
cfg80211 wireless extensions compatibility
is needed.

Which wlan card do you have? I think you dont have wlan card firmware installed. For example my Intel PRO/Wireless 5100 AGN needs sys-firmware/iwl5000-ucode.

Hope not to speak too early, but latest update of wpa_supplicant seems to be resolutive!

On a fresh installation, only by updating wpa_supplicant made it see the wireless modem.
