net working in win2k but not in RHLinux 9 using RTL 8139/810x nic


hello everybody,
i am a newbie for linux
iam getting few problems....

let me tell in details what h/w i have:

cyrix M-II 233MHz processor(i know i need 400MHz at least for GUI still i experimented that and i succeeded in running that)
RAM is okay (256MB)
via chipset motherboard
realtek RTL 8139/810x family nic(Ethernet card)
yamaha OPL3-Sax WDM (SOUND CARD)

the LAST ONE is working with windows 2000 pro but didn't detected(failed) with red hat 9(i have dual boot system)

one more and IMPORTANT PROBLEM is that my INTERNET is NOT woking in Linux but in win2k it is running well .
my system detected realtek card as some other card(something like SURECOM)

my static IP address is 61.16.148.196
subnet mask is 255.255.255.192
DNS and gateway are 61.16.148.65

i tried few commands and following are the results:

# ifconfig

You'll need to add the default route (gateway):
route add default gw 61.16.148.65

That would make sense considering that your subnet mask only gives you access to hosts .193 to .254. Are you sure you have the correct netmask and gateway?

see about a year ago when i took this LAN connection (CABLE ) he gave me the DNS as 61.16.148.193 but after few months he again gave me (and all others ofcourse) 61.16.148.65/61.16.148.33
and i am sure that i am using these settings as shown by tcp/ip properties :
ip address : 61.16.148.196
subnet mask: 255.255.255.192
default gateway: 61.16.148.33
preffered DNS: 61.16.148.33

any suggestions???

The gateway will need to be in the same ip range as your netmask. I would double check with your provider what IP address, network mask and gateway you should be using.
