That's why I'm asking. ifconfig ra0 mtu 2000 returns an error (for all value over 1500). Don't have the exact error message here, sorry. This is with a ralink 2500 chipset (PCI card). OS is Ubuntu 6.06. Is this becasue of the driver ? Or ifconfig limitation ? Regards, David ---------------------------------------------------------------- VOLJADSL Paketi po vasi meri.
