Problems with networking [iwl4965] [solved]
« on: March 22, 2009, 11:31:00 AM »
My bootlocal.sh
Code: [Select]
modprobe iwl4965
/opt/wlan0.sh
iwconfig wlan0 essid "blahblahnet"

And wlan0.sh
Code: [Select]
pkill udhcpc
ifconfig wlan0 192.168.1.100 netmask 255.255.255.0 broadcast 192.168.1.255 up
route add default gw 192.168.1.1
echo nameserver 208.67.222.222 > /etc/resolv.conf
echo nameserver 208.67.220.220 >> /etc/resolv.conf

The connection dies when I start to download something. When I restart networking (up down the interface and add default route again) it downloads 100-250 kbytes and dies again.

If I just ping router or internet host, connection still alive. Is it problem of my configuration or drivers?

UPD: This is a kernel bug. I built latest 2.6.29 kernel, repacked initrd with new modules and used this firmware:
http://www.intellinuxwireless.org/iwlwifi/downloads/iwlwifi-4965-ucode-228.57.2.23.tgz

And wifi is working now.

Hi,

Same problem,
I've tried everything.
I get a connection but after a few kb, the connection stops.
No errors in dmesg, all modules loaded (iwl4965 etc...)
A real pain.

Any thoughts?

Is it the firmware iwlwifi-4965-1.ucode ?
I notice that Ubuntu calls the newer iwlagn firmware.
How could one update the firmware?

I copied firmware from ubuntu too. May be it is the problem?

Hi,

Same problem,

It seemed, I found a solution. Try build latest kernel. I think it is kernel bug.
