 Posted: Tue Mar 23, 2010 3:55 am Post subject: Intel Wifi 5300 keeps dropping (sort of?) |
 |
|
The "sort of" is because both iwconfig and ifconfig show everything is fine. But nevertheless, the connection is effectively dropped. The only solution is to restart net.wlan0. Suffice it to say, this is a tedious and annoying solution. Googling hasn't revealed much except that this used to be a problem on Windows, too.
I have used kernel 2.6.31, 2.6.33 and 2.6.34-rc2 and they all have the same problem. I'm running ~amd64 (though was running regular amd64) on an Lenovo ThinkPad T500. Any thoughts?
Here's my /etc/wpa_supplicant/wpa_supplicant.conf:
| Code: |
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
#ap_scan=2
fast_reauth=1
#eapol_version=1
network={
key_mgmt=NONE
priority=-99999
}
network={
ssid="XXX"
psk="XXX"
priority=2
}
|
/etc/conf.d/net:
| Code: |
dns_domain_lo="local"
config_lo="127.0.0.1"
config_eth0=( "dhcp" )
modules=( "wpa_supplicant" )
wpa_supplicant_wlan0="wext"

It seems that you are using an eth0 and wlan0, don't use them at the same time.
Furthermore, I think that:
| Quote: | | wpa_supplicant_wlan0="wext" |
should be
| Quote: | | wpa_supplicant_wlan0="-Dwext" |
# it's a wpa_supplicant parameter
If that does not fix your problem, try below:
Can you disable the net infrastructure (for a while):
| Code: | | /etc/init.d/net.wlan0 stop |
Use this as your wpa_supplicant:
| Code: | ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
network={
key_mgmt=NONE
priority=-99999
}
network={
ssid="XXX"
psk="XXX"
priority=2
} |
And start it as:
| Code: | | wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf -dd |
Can you post the output of that please? Then, check if your connection works:
or if you don't have dhclient
Wait 10 seconds, you should be able to browse the net. |

| I think you missed the issue. It's not that I *can't* connect; it's just that the connection drops after a bit and I have to restart net.wlan0. Sometimes I can go an hour or more without a drop. Other times it's 30 seconds. But it does successfully connect, authenticate and all that jazz. So your corrections make no difference to me (I did try them just in case -- the results were the same). |

| Do you see anything in dmesg when it disconnects? |

Nothing anywhere. Even ifconfig and iwconfig still show it as connected. I just can't use the connection (ping fails, can't load web pages (they time out), etc). |

| What is the kernel name of your driver? (e.g. iwl3945?) |

IWLWIFI or IWL5000 are the config options, but the module is named iwlagn. I currently have it built-in to the kernel. |

Can you post this :
| Code: |
# cd /usr/src/linux
# cat .config | grep -i 802
# cat .config | grep -i kill
# cat .config | grep -i iwl

Can you post the output of this?
| Code: | | for i in `ls /sys/module/iwl5000/parameters`; do echo ">>>"$i"<<<"; cat /sys/module/iwl5000/parameters/$i; done |

Although it wasn't iwl5000, but iwlagn. So I guess that's the driver name. |

Try starting the kernel with the following appended to the kernel bootline:
kernel /boot/kernel .. .. .. iwl5000.11n_disable50=1 iwl5000.fw_restart50=1 iwl5000.swcrypto50=1
Does it help? |

Before I reboot: I can't turn off n based networking (assuming that's what 11n_disable50 does) because that's what our router uses. I don't currently have an option to do it differently. |

| Nope, those changes didn't help. It dropped again after a few minutes. |
