Unable to activate wifi on Linux

[dkebler]

I'm running auyufan latest stable with updated kernal. on a Rev B board

• Like the OP
• lsmod shows that cfg80211 is there
  

but ifconfig show two wlan,  wlan0 and wlan1

wlan0     Link encap:Ethernet  HWaddr 34:c3:d2:e4:38:ce  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

wlan1     Link encap:Ethernet  HWaddr 36:c3:d2:e4:38:ce  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

Showing two (with different MAC addresses) is pretty weird considering there is only one adaptor in the module.
BTW I disconnected the module to confirm the two only appear together when the module is connected.
This weirdness seems related to my woes.

Also the BT part of the module is working fine.

So whichever of the the two is the "real" adapter neither of these can I get working (with Network Manager).

I do get the same "missing power" for both.

Ifup doesn't give any error and Network Manager is set to "managed=true" but still the wlan(s) is greyed in NM.

So I tried doing things manually


ip  link  set  wlan0  up
returns no error


ip  link  show  wlan0

wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT group
default qlen 1000

    link/ether 34:c3:d2:e4:38:ce brd ff:ff:ff:ff:ff:ff

wpa_supplicant  -D  nl80211  -i  wlan0  -c  <(wpa_passphrase  ""  ""  )  & dhcpcd  wlan0

Successfully initialized wpa_supplicant

nl80211: deinit ifname=wlan0 disabled_11b_rates=0
wlan0: Failed to initialize driver interface


-----------------
more suggestions please.  I've tried all on this thread and also those related to gettting  WIFI on network manager working.
