 |
|
I am runnning gentoo on a raspberry pi with an Edimax EW-7811UN wifi-usb-key and everythings works fine so far. When I start net.wlan0 I receive following lines
| Code: | * Bringing up interface wlan0
* Starting wpa_supplicant on wlan0 ...
Successfully initialized wpa_supplicant
ioctl[SIOCSIWAP]: Operation not permitted
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
* Starting wpa_cli on wlan0 ... [ ok ]
* Backgrounding ... ... [ ok ] |
The lines starting with ioctl[..]... are bothering me, since I do not understand what is going on. Research on google did not help.
What does it mean and how can I fix it?
Here is my lsusb
| Code: | Bus 001 Device 005: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]
Bus 001 Device 004: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub |
and a part from my conf.d/net
| Code: | ...
wpa_supplicant_wlan0="-Dwext"
config_wlan0="192.168.178.10 netmask 255.255.255.0 broadcast 192.168.178.255"
routes_wlan0="default via 192.168.178.1"
dns_servers_wlan0="192.168.178.1"

BlueShark ... changing the above to '-Dnl80211' should resolve the issue. Also, you might also want to add '-qq' (quiet, quiet) to suppress wpa_supplicant output.

Thank you for your answer.

When I do so, I receive the following message
| Code: | * Bringing up interface wlan0
* Starting wpa_supplicant on wlan0 ...
Successfully initialized wpa_supplicant
nl80211: Driver does not support authentication/association or connect commands
nl80211: deinit ifname=wlan0 disabled_11b_rates=0
wlan0: Failed to initialize driver interface
* start-stop-damon: failed to start '/user/sbin/wpa_supplicant' [ !! ]
* ERROR: net.wlan0 failed to start

Actually, I do not want to suppress those messages. I rather want to understand what is going on.
Unfortunatelly, today has something changed. Sometimes - and that is really weired - an additional line appears when starting wlan0
| Code: | * Bringing up interface wlan0
* Starting wpa_supplicant on wlan0 ...
Successfully initialized wpa_supplicant
rfkill: Cannot open RFKILL control device
ioctl[SIOCSIWAP]: Operation not permitted
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
* Starting wpa_cli on wlan0 ... [ ok ]
* Backgrounding ... ... [ ok ] |
I never have seen the line rfkill: Cannot open RFKILL control device before. What does that mean. How does it appear. What can I do to fix it. |
