network faliure toshiba sattelite

Hi
I've installed the drivers for my ethernet car (marvell yukon) and wifi (2200bg) but they generaly don't work. Sometimes the ethernet car goes up and I can get an IP addres . This times the wireless detect my wifi network. But, most times, the ethernet can't connect (it gives me distinct error messages) and the wifi can't detect the wlan .

I don't think it will be a driver problem cause in ocassions they work properly . I've used PCI=ROUTEIRQ in grub conf since using dmesg can see a "dissabling IRQ12" message, but it keeps the same .

Any suggestion?? thanks
