Hi Guys!

I have p4s533 asus motherboard
the linux redhat 9.0 does not recognize onboard
lan adapter

in BIOS its on
in Windows its works

if somebody knows what to do
thanks in advance

onboard netcard is not enough information

you need to know what chipset its using.

type dmesg or lspci and paste the results back

its has sis900 lan adapter
sometimes its recognize it
sometimes its does not
i have AHT-e300 modem connected to the sis900
the modem has dhcp server,its has 10.0.0.2 static ip
i cant ping modem from my comp i cant get ip from its dhcp server
may the porblem is sis900 driver?

in WinXp all works ok

i think(read guess) problem is with the dhcp
do you power the modem on before the pc or after the pc starts?

i always start modem first
i saw in win the comp has pppoe connection
to modem may be something wrong
with pppoe setting under linux redhat 9?
may be something wrong in TCP/ip stack
setting ?

ok

next time this happens type the following commands

mii-tool
ifconfig

record the output and post it here

thanks

most welcome, let me know how it goes, my guess its either
1. dhcp client not running proeperly
2. cabling problem, these 2 commands will help diagnose it
