Hello everyone,
I had installed on my system only the wpa_supplicant tool to connect to my wireless network. Recently, I should install something (maybe an update to firefox?) that also install the wireless-tools. After that, on the next reboot my PC didn't automatically connect to the wireless as usual. I got an error like this
| Code: | * Starting wlan0
SIOCSIFFLAGS: Unknown error 132
SIOCSIFFLAGS: Unknown error 132
SIOCSIFFLAGS: Unknown error 132
* Configuring wireless network for wlan0
* wlan0 does not support scanning
* You either need to set a preferred_aps list in /etc/conf.d/wireless
* preferred_aps=( "ESSID1" "ESSID2" )
* and set associate_order_wlan0="forcepreferred"
* or set associate_order_wlan0="forcepreferredonly"
* or hardcode the ESSID to "any" and let the driver find an Access Point
* essid_wlan0="any"
* or configure defaulting to Ad-Hoc when Managed fails
* adhoc_essid_wlan0="WLAN"
* or hardcode the ESSID against the interface (not recommended)
* essid_wlan0="ESSID"
* Failed to configure wireless for wlan0 |
It was a little strange for me because I had selected wpa_supplicant over wireless-tools on the /etc/conf.d/net file.
I uninstalled wireless-tools and everything worked just fine as before.
I start to search what could be the problem and I found some results that I didn't fully understand.
When both programs are installed, I found that the problem is the position of the line: "modules=( "dhcpcd" )" on the /etc/conf.d/net file. If that line is placed after "modules=( "wpa_supplicant" )" it didn't work.
I mean, when this is my /etc/conf.d/net file:
| Code: | modules=( "ifconfig" )
config_eth0=("dhcp")
fallback_eth0=( "null" )
modules=( "wpa_supplicant" )
modules=( "dhcpcd" )
wpa_supplicant_wlan0="-Dwext" # For generic wireless
config_wlan0=( "dhcp" )
dhcpcd_eth0="-t 3" |
I get this:
| Code: | # /etc/init.d/net.wlan0 restart
* Starting wlan0
SIOCSIFFLAGS: Unknown error 132
SIOCSIFFLAGS: Unknown error 132
SIOCSIFFLAGS: Unknown error 132
* Configuring wireless network for wlan0
* wlan0 does not support scanning
* You either need to set a preferred_aps list in /etc/conf.d/wireless
* preferred_aps=( "ESSID1" "ESSID2" )
* and set associate_order_wlan0="forcepreferred"
* or set associate_order_wlan0="forcepreferredonly"
* or hardcode the ESSID to "any" and let the driver find an Access Point
* essid_wlan0="any"
* or configure defaulting to Ad-Hoc when Managed fails
* adhoc_essid_wlan0="WLAN"
* or hardcode the ESSID against the interface (not recommended)
* essid_wlan0="ESSID"
* Failed to configure wireless for wlan0 |
However, if I changed that line an put it before "modules=( "wpa_supplicant" )":
| Code: | modules=( "ifconfig" )
config_eth0=("dhcp")
fallback_eth0=( "null" )
modules=( "dhcpcd" )
modules=( "wpa_supplicant" )
wpa_supplicant_wlan0="-Dwext" # For generic wireless
config_wlan0=( "dhcp" )
dhcpcd_eth0="-t 3" |
It works:
| Code: | # /etc/init.d/net.wlan0 restart
* Caching service dependencies ...
* Cannot add provide 'net', as a service with the same name exists! [ ok ]
* Starting wlan0
SIOCSIFFLAGS: Unknown error 132
SIOCSIFFLAGS: Unknown error 132
* Starting wpa_supplicant on wlan0 ... [ ok ]
* Starting wpa_cli on wlan0 ... [ ok ]
* Backgrounding ... |
[Note: Even though I get those 2 error messages, my network was still working as normal. I'm still working on why are those errors there.]
However, I uninsintalled wirelss-tools and reload the wireless modules
| Code: | # emerge --unmerge net-wireless/wireless-tools
# rmmod iwlagn
# modprobe iwlagn |
and put the /etc/conf.d/net configuration file back to the previous state (dhcpcd after wpa_supplicant)
| Code: | modules=( "ifconfig" )
config_eth0=("dhcp")
fallback_eth0=( "null" )
modules=( "wpa_supplicant" )
modules=( "dhcpcd" )
wpa_supplicant_wlan0="-Dwext" # For generic wireless
config_wlan0=( "dhcp" )
dhcpcd_eth0="-t 3" |
and it worked without any error:
| Code: | # /etc/init.d/net.wlan0 restart
* Stopping wlan0
* Bringing down wlan0
* Stopping dhcpcd on wlan0 ... [ ok ]
* Shutting down wlan0 ... [ ok ]
* Stopping wpa_cli on wlan0 ... [ ok ]
* Stopping wpa_supplicant on wlan0 ... [ ok ]
* Starting wlan0
* Starting wpa_supplicant on wlan0 ... [ ok ]
* Starting wpa_cli on wlan0 ... [ ok ]
* Backgrounding ... |
Is there anything that I am missing there? have I overlooked something?
I would appreciated any tips or suggest about where the problem could be.
Thanks! |
