I use Mandriva 2005 LE right now. It works just fine. But when I try to install Mandriva 2007.0, or Fedora my network driver isn't working properly.
It's disconnect after few secconds and connect again cyclic. Settings are the same in the both systems.

Can you post some of the log errors please? What modules do you have loaded? What is your hostname set to? DHCP or static IP?

Regards

For log errors I have to rebuild driver for debug. I shall make it in the evening. My settings: essid "darion64", static ip address. I load rt2500 for ra0 wakeup. Modules come from distribution with kernel package. I tried to compile from serialmonkey site cvs version - no changes.
I has forgotten to tell that signal is very weak. It works at 500 m distance with no direct visibility. But quality is about 60% at 11Mbps.
I connected to my friend with the same card at AdHoc mode. New interesting thing: when my friend (WinXP) try to upgrade driver, there is the same problem ! I mean cyclic reconnect !
Maybe, we need to update the driver both?!

Maybe using the cvs version has a little to do with it. Maybe not.

Have you tried an older stable version of the driver? I have had success many times with using older packages when something goes south.

Regards

I can't compile old driver with new kernel. Only New driver supports new kernel.

What kernel version are you running now? Did you get it from cooker? Do you have the headers installed? Do a

ls -laR /lib/modules/your-kernel-name/kernel/drivers/

And post it here.


Regards

I have installed source kernel packages in all systems. The old driver is not compiled owing to incompatibility of system calls with a new kernel.
Output from working system /lib/modules/2.6.11-6mdk/kernel/drivers/ /lib/modules/2.6.11-6mdk/kernel/3rdparty/
No cooker. Just standart Mandriva 2005LE kernel.

Fedora 6 & Mandriva 2007.0 with standart kernel not working.

We are talking about the rt2500 driver, correct? What's inside

/etc/sysconfig/network-scripts/wireless.d/

You mentioned that the settings are the same as Mandy 2005. What 'settings' are those?

Regards

/etc/sysconfig/network-scripts/ifcfg-ra0 :

DEVICE=ra0
BOOTPROTO=static
IPADDR=192.168.30.2
NETMASK=255.255.255.252
NETWORK=192.168.30.252
BROADCAST=192.168.30.3
ONBOOT=yes
METRIC=10
MII_NOT_SUPPORTED=yes
USERCTL=yes
WIRELESS_MODE=Ad-Hoc
WIRELESS_ESSID=darion64

What is inside

/etc/sysconfig/network-scripts/wireless.d/

Regards,

It is empty.
# cat /etc/modprobe.conf | grep rt2500
alias ra0 rt2500

And ifcfg-ra0 - that's all.

Sorry for the delay in getting back here. I had emergency surgery over the weekend. I'll be able to look over you post soon.

Regards

Thanks for your try to help, ray_80 !
I'm find my problem and resolve it. It's new driver rt2500. It use 0 dB tx level and up to 2dB when try to scan ap. Max level for my card is 4 dB.
I love opensource ! I install Mandriva 2008.0, recompile module for debug. And now I have to say: IT IS NOT MANDRIVA PROBLEM.

Sorry, it's not enough to increase tx power. It's more serious bug in driver that use automaticaly tune receive level with R17 register. I have to talk to driver autors about this bug. Driver included in Mandriva 2005LE never mistaken with receive level and always setting up an appropriate R17 value.
