that card comes in two flavors, and I got both and for me, they work really fast above 2.6.16 kernel and slow as heck with 2.4.31 kernel.

note: suse has a setting in yast to do networking "by traditional ifup" or "by network manager" and if you chose "by network manager in suse that will mess you up, especially on wireless, or it did for me at least.

also in yast/suse in netowork devices, you;ll find a little drop down box for dhcp options, make sure "change hostname by dhcp is off".

but you're better off here in slackware, it listens to what you tell it too

i tried root@slackw:~$ lspci | grep Realtek
but nothing happens
new line appears
i tried netconfig and configured my network but it said it couldn't know the lan card
i tried ifconfig (lo) and ip appears
when i install the driver on slack and typed if config (eth0)and ip appears then
did any body know a solution for my card i think it is in lo and eth0

please, as root, type the command "lspci" (without quotes) and post the result of this. also, add the result of "ifconfig -a".

don't get confused by that the chipset is often used by other vendors and only their name appears in first place.

look man
i have configured my network with
>>netconfig
and my ip 196.168.1.123
mask 255.255.255.0
gateway 196.168.1.1

>>lspci
alot of things but what i think u want to know is
00:0b.0 ethernet:unknown device 1904:8139 (rev 01)
>>ifconfig -a
lo
link encap :local loopback
inet addr:127.0.0.1 mask:255.0.0.0
uploopback running MTU :16436 Metric:1
Rx packets=0 errors=0 dropped=0 overruns:0 frame:0
TX packets=0 errors=0 dropped=0 overruns:0 carrier:0

then can u solve my problem??????????
remmber that when i used my installation filies lo->eth0,ip and mask and
gateway are written correctly

I agree with you. Infact, I do have a LAN card which I have driver for 2.4.x and 2.5.x only. The driver doesn;t exist in any of the linux distributions out of the box. I have to manually compile it. The card seems to be RTC8139d by Intex and driver is provided by Silan. The module name is sc92031
Here's info about my card
So, after trying many other kernel 2.6.x based distributions with no luck, I am back using Slackware 10.2 with kernel 2.4.31 and it works fine. If anyone could help me make some changes to the source file of the driver inorder to make it work under kernel 2.6.x, I would feel blessed.

why doesn't the company of my card relase a driver for kernal 2.6 or 2.x kernal

You'll have to ask them and for the last time, it's kernel.

now i couldn't work with any new kernal and any new distribution too
is this a good solution
then shall i leave linux???

Or you may replace your Ethernet card. The regular 8139 cards work fine.
Or stick with Slackware (2.4.x) if not necessary to have 2.6.x.

In my opinion it's not a major issue if you have only one hardware not working.

i may have the same problem with other card too

Do a lspci with your network card on some OS and kernel version which you got it working, and check if it is similar or even identical to this And post back your results.

i have did that but i had
00:0b.0 ethernet:unknown device 1904:8139 (rev 01)

Did you recompiled your kernel and enabled Realtek 8139 support ? And what kernel version are you running currently ?
