Hi,
I USED to able to connect but I cannot anymore.
I do see my card running iw dev and wpa_supplicant should be running.
dmesg | grep iwlwifi do not report any particular error:
| Code: |
[ 2.835606] iwlwifi 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control

iw dev
| Code: |
phy#0
Interface wlp3s0
ifindex 4
wdev 0x1
addr 0c:8b:fd:a5:5a:2d
type managed
|
I can trigger manually the connection to an unprotected network through:
iw dev wlp3s0 connect NETWORK_NAME
After that iw dev gives me:
| Code: |
phy#0
Interface wlp3s0
ifindex 4
wdev 0x1
addr 0c:8b:fd:a5:5a:2d
ssid D-Link
type managed
channel 6 (2437 MHz), width: 20 MHz (no HT), center1: 2437 MHz
|
and later I tried to activate dhcp on it through
dhcpcd wlp3s0
But it says it wait for the carrier... then we have a timeout and so, no connection.
What I should start to check?[/code] |

If you could connect in the past, and can't do that anymore, consider what has been changed.
New kernel?
Big world update?
PC hardware upgrade?
New wifi router?
5 year old sister hanging out with root's terminal?
Broken microwave oven around?
What software controls your wireless interface? Network manager? Wpa_supplicant with hand-made config? /etc/init.d/net.wlp3s0 service? Some cusstom script? |

I disabled something like mac82011, apparently.
I restarted from a fresh kernel and reconfigured it from scratch... |
