hi , as you told me I used dmesg. here is the output : NE*000 ethercard probe 0x300 00 80 48 fc e6 58 eth0 : NE2000 found at 0x300, using IRQ 3 eth0 : Tx timed out,lost interrupt? TSR=0x1, ISR=0x17 , t=650 the last line above is repeated 5 times for different values of ISR and t Also when I used route add -net default gw (IP_address) I got the following error : SIOCADDRT : Network is unreachable Why , whats wrong? And yes using /etc/rc.d/init.d/network restart gives the error route: netmask doesn't match route address SIOCADDRT : Invalid argument SIOCADDRT : Network is unreachable SIOCADDRT : Network is unreachable Along with this the proper syntax of route command is also shown .
