Hi Folks,

wifi suddenly failed to connect and I can't bring it up:

Code:

ip link set wlan0 up

Code:

Try the usual wifi commands to see if your ssid is being broadcasted
iwlist wlan0 scan
or
wavemon -i wlan0

Do you also have a patch lead connected to the NIC?

I do not know.

However I play with iwlist (totally irrelevant) and suddenly wlan0 is UP

Code:

ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000
    link/ether 00:26:6c:3e:7f:38 brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether c6:4e:d9:58:0b:4c brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.16/24 scope global wlan0
       valid_lft forever preferred_lft forever

and

Code:

udhcpc -i wlan0
udhcpc: started, v1.36.1
udhcpc: broadcasting discover
udhcpc: broadcasting select for 192.168.1.16, server 192.168.1.1
udhcpc: lease of 192.168.1.16 obtained from 192.168.1.1, lease time 86400

How was fixed, I do not know. It reproduced and I could not brought it up with iwlist, restarting networking or network-manager. Rebooting in this last instance worked and wlan0 was up without intervention.

Thanks!
