I have a RPI Model B (Revision 000e) running stretch lite (command line only) and with up-to-date software and firmware. I would like to enable WiFi by using a Sitecom WLAN USB adapter (model wla2000).
When I plug in the WiFi adapter and reboot, the WiFi adapter seems to be recognized:
$ ip addr (...) 3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000 link/ether 00:0c:f6:c7:73:0f brd ff:ff:ff:ff:ff:ff
$ ifconfig (...) wlan0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 ether 00:0c:f6:c7:73:0f txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
However, I can not turn on the WiFi via any of these commands:
$ sudo ip link set wlan0 up $ sudo ifconfig wlan0 up
When I try to set the WiFi legal channels via:
'$ sudo raspiconfig' -> '4 Localisation Options' -> 'I4 Change Wi-fi Country'
I get the error message:
Could not communicate with wpa_supplicant
The following is in my
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1
Any help is very much appreciated.
