Posted: Fri Apr 19, 2013 12:40 am Post subject: [SOLVED] Unable to start wireless net after new install |
|
|
This is an install on an Acer Aspire One netbook which has the Atheros chipset for wireless (ath5k module). It worked fine with the Rescue CD install that I did. It even worked after the initial reboot. Then the new udev got involved, changed the name from wlan0 to wlp3s0 and it ceased.
The ath5k module loads without problem. When I try to start net.wlp3s0 I get:
Code: |
* Bringing up interface wlp3s0
* configuring wireless network for wlp3s0
* Scanning for access points
* Found "Mill Bay Marina" at 00:27:22:8C:EF:A7, managed
* Found "BCSstudent" at 0E:18:0A:04:08:B2, managed, encrypted
* Found "BCSstaff" at 0A:18:0A:04:08:B2, managed, encrypted
* Connecting to "Mill Bay Marina" in managed mode (WEP Disabled) ... [ !! ]
Error for wireless request "Set Frequency" (8B04):
SET failed on device wlp3s0 ; device or resource busy
|
In dmesg, I see:

Initially, I was seeing errors that seemed to be related to ipv6, so I removed that from my system, to no avail.
Anyone have any thoughts as to what could be going on here?

does ifconfig show an ipaddress on your network? _________________ Defund the FCC. |

ihtruelsen ... your problem is really due to your using iwconfig, you should switch to using cfg80211 natively, and not wext (via cfg80211's compatability layer). In short, wpa_supplicant rather than wireless-tools. The above connection may have failed for a number of reasons, from the dmesg it seems that its an issue with authentication, "reason=3" is a your STA deauthenticating, probably as it couldn't establish a connection with that particular AP (ie, no password available, the AP is hung, or the authentication negociation times out). As I remember the above error shouldn't cause the connection to fail.
Please check you have all of CFG80211/MAC80211 enabled, and CFG80211_WEXT (if you still plan on using wext).
Code: | awk '/(WEXT|(CFG|NL)80211)/' /usr/src/linux/.config
CONFIG_WEXT_CORE=y
CONFIG_WEXT_PROC=y
CONFIG_CFG80211=m
# CONFIG_NL80211_TESTMODE is not set
# CONFIG_CFG80211_DEVELOPER_WARNINGS is not set
# CONFIG_CFG80211_REG_DEBUG is not set
CONFIG_CFG80211_DEFAULT_PS=y
# CONFIG_CFG80211_INTERNAL_REGDB is not set
CONFIG_CFG80211_WEXT=y |
/etc/conf.d/net would look something like the following:
Code: | modules_wlp3s0="!plug wpa_supplicant dhcpcd"
wpa_supplicant_wlp3s0="-Dnl80211 -qq"
wpa_timeout_wlp3s0="15"
config_wlp3s0="dhcp"
dhcpcd_wlp3s0="-t 10"
enable_ipv6_wlp3s0="false" |
You would then emerge wpa_supplicant and configure wpa_supplicant.conf, you can use wpa_gui if you have the "qt4" use flag set, or manually, an example:
/etc/wpa_supplicant/wpa_supplicant.conf
Code: | ctrl_interface=DIR=/run/wpa_supplicant GROUP=wheel
update_config=1
network={
ssid="Mill Bay Marina"
auth_alg=OPEN
proto=RSN # for WPA2 .. dependent on the AP's capabilities
key_mgmt=WPA-PSK
psk=<your_passphrase_here>
} |
The network stanza isn't needed if you use wpa_gui as you can select and configure the network and wpa_supplicant will write the config for you.

This can be disabled via "enable_ipv6", see the above.

I changed my setup as suggested and the results are very much the same.
Code: |
[ 393.761672] wlp3s0: authenticate with 00:27:22:8c:ef:a7
[ 393.767582] wlp3s0: send auth to 00:27:22:8c:ef:a7 (try 1/3)
[ 393.769510] wlp3s0: authenticated
[ 393.771267] wlp3s0: associate with 00:27:22:8c:ef:a7 (try 1/3)
[ 393.774259] wlp3s0: RX AssocResp from 00:27:22:8c:ef:a7 (capab=0x21 status=0 aid=3)
[ 393.775637] wlp3s0: associated
[ 393.779943] wlp3s0: deauthenticating from 00:27:22:8c:ef:a7 by local choice (reason=3)
|
And it just keeps repeating in dmesg.
And DONAHUE:
There is no IP address in ifconfig or association in iwconfig:
Code: |
wlp3s0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

ihtruelsen ... can you please try with the following:
/etc/modprobe.d/ath5k.conf
Code: | options ath5k nohwcrypt=1 |
... assuming your driver is built as a module.

first four steps are to ensure interfering processes are not running; expect already stopped and does not exist
Code: | /etc/init.d/net.wlp3s0 stop
/etc/init.d/wpa_supplicant stop
/etc/init.d/dhcpcd stop
rm /var/run/wpa_supplicant/wlp3s0
ifconfig wlp3s0 up
iwlist wlp3s0 scan
iwconfig wlp3s0 essid Mill Bay Marina
dhcpcd wlp3s0
ping -c2 -Iwlp3s0 8.8.8.8 | pings?
alternate is use wpa_gui to configure the connection presuming you have a gui and that wpa_supplicant was emerged with USE="qt4" Note that Mill Bay Marina is unprotected. _________________ Defund the FCC. |

Thanks for the thought Khayyam, but that had no effect. |

Okay Donahue, as expected the initial commands are all process already stopped and no such file for the rm command.
There is no output for the ifconfig up command.
The iwlist command returns:

Among others.
The iwconfig command produces no output, however iwconfig does not show any associated AP.
The dhcp command produces:
Code: |
dhcpcd[1688]: version 5.6.7 starting
dhcpcd[1688]: all: configured as a router, not a host
dhcpcd[1688]: wlp3s0: waiting for carrier
dhcpcd[1688]: timed out
dhcpcd[1688]: allowing 8 seconds for IPv4LL timeout
dhcpcd[1688]: timed out
|
And finally the ping command:
Code: |
PING 8.8.8.8 (8.8.8.8) from 0.0.0.0 wlp3s0: 56(84) bytes of data.
From 127.0.0.1: icmp_seq=1 Destination Host Unreachable

I found the problem. It was networkmanager.
I noticed it trying to do something during the boot process, but the screen cleared so quickly that I was never able to see what was going on. So, out of desperation, I unmerged it and rebooted. Immediately I was able to get connected and am now cruising along once again.
Thanks for all your help and I hope my frustration helps out someone else. |

ihtruelsen ....
urrrghh, its always good to know what factors might be in the mix, as that is what DONAHUE was trying to rule out above with stoping all known services ... well, at least its solved.
