After connecting wlan0 to bridge interface (and then removing it), can't connect to AP
- by gmonk
I'm on a laptop running Debian Jessie with kernel 3.13-1-amd64; lspci shows that my wireless NIC + driver is
04:00.0 Network controller: Intel Corporation Wireless 3160 (rev 83)
Subsystem: Intel Corporation Dual Band Wireless-AC 3160
Kernel driver in use: iwlwifi
This has been working without any problems, until I tried creating a bridge for lxc containers to use. I did the same thing as this person here: How-to set up a network bridge on a laptop for LXC use? -- and ended up having the same problem as this poster did, so I decided to "undo" my actions.
This hasn't been successful.
Actions taken so far:
To configure the bridge:
#> ip link add type veth
#> iw dev wlan0 set 4addr on
#> ifconfig veth0 up
#> brctl addbr br0
#> brctl addif br0 wlan0
#> brctl addif br0 veth0
#> ifconfig br0 192.168.0.4/24
#> ifconfig wlan0 0.0.0.0
To "deconfigure":
#> brctl delif br0 wlan0
#> brctl delif br0 veth0
#> iw dev wlan0 set 4addr off
#> ifconfig veth0 down
#> ifconfig wlan0 down
#> ifconfig br0 down
#> brctl delbr br0
Now, dmesg and /var/log/syslog show repeated attempts at connecting to the AP that was working before, which fail after authentication:

The things that jump out at me are "deauthenticating ... by local choice( reason=3)" and the lines that contain "(reason=15)".
I've tried various fixes:
iwconfig wlan0 power off
killing wpa_supplicant
connecting with iwconfig + dhclient instead of gnome's network -manager
explicitly configuring wlan0 in /etc/network/interfaces
creating a /etc/wpa_supplicant.conf file
...but nothing seems to work.
I'm not sure what I did wrong, or what step I've skipped in trying to get wlan0 back as a non-bridged device -- I removed it from the bridge and then deleted the bridge itself.
Any ideas?
