I looked and searched everywhere.I found something useful and use them but still I have problems.
I use a laptop with slackware 10.0 and kernel 2.6.7.I had an onboard ethernet device(sis900)which has bug according to other users on net.
So I try to connect my Netmaster Cable Modem via usb.Here problems being occure.I closed the ethernet adapter by rmmode sis900.Then I checked my sistem with lsconfig it gives me that my usb connection became eth0.And it gives its ip as 192.168.100.2.When I enter the konqueror 192.168.100.1 it opens the cable modem wizard page.But after it didn't give outer ip.So I cant login to net.I only see modem wizard page.
Any solutions for me??

Ok I solve the problem.
After ifconfig and see ip as 192.168.100.1;
ipconfig eth0 176.244.98.26(ip looked from windows) netmask 255.255.240.0
route -n
route add default gw 176.244.94.1(this ip from route table below)
Then pico /etc/resolve.conf ----> netmask 212.156.4.4

After these steps I coneect my pc to internet but my connection speed is too slow as 14.4kpbs.But it must be much more faster than this.Bcs its cable and usb...

Edit:
My ping times are about 100 or 200 ms.But my download rate is nearly 200 bayt/s. What will be the wrong?
