Hello guys, in the past i've used opensuse 10.2 and was able to login in the internet easily and the only things that has changed since then is i updated my modem and intall opensuse 10.3. now I can't connect to the net anymore, I have research the net for a whole day, and it seems that I have everything setup right, but just can't make the connection. I also tried to install kubuntu 7.10 and the problem still persist then switched back to opensuse 10.3 with no luck. any help will very much appreciated.

That's a good one.. first thing to do is test the network hardware..

Try pinging 127.0.0.1 and then your router ip. If you use ifconfig -a it should show you both the localhost IP and your network card IP.. anything wrong there?

It's likely that your router isn't running it's dhcp properly, or it isn't enabled.

thanks, the network card is setup like this, dynamic address to DHCP, the IP address is blank, the subnet mask is blank as well. does this needs to configure properly? please refresh my mind on how to pinging. thanks

Hello guys, the battle still going over here, get this, I am connecting to the net using via live cd only and this.. with no trouble , when I tried to load up the os (kubuntu 7.10 this time) I have installed on the harddisk, it loads up fine but my Knetwork manager cannot activate my network connection above 57%!!! and this won't make my connection get through. I can't wrap my head around this! (exhausted maybe). any help? thank you again

Hmmm.. so nothing wrong with the hardware. Is it the kubuntu live cd that is working? If that's the case then copying the settings "should" do the trick.

The output from ifconfig (if it is working) should look like...

and to find if the network hardware in your machine is detected and running try lspci -v look for an entry like...

---

Now if you run both those commands from the working live cd, and then on either system which isn't working it will probably give us the reason it isn't connecting. Most likely it's a driver module missing. (check in rcS.d/modules for a network driver module) The hardware is possibly unusual and not being detected when you installed.

The debian documentation is about the best around. This will apply to kubuntu http://www.aboutdebian.com/network.htm (unless they have messed with it too much) Read through.. about 3/4 of the way down page 1 there is a lot of information about configuring hardware..
As for suse.. you have me there.. I think (my opinion.. it will not work properly for me.. damn you Novell and M$) it's too broken to be usable now.

I think we need some info about your network hardware to troubleshoot this further.

thanks varnull for the links, somehow I managed to configured out this @#$%^^# network. what I did is, I load up live cd, then went to network settings and basically copied all the numbers for IP, netmask, broacast. then started the os (from the harddisk) and replicated the same setting I had from the live cd network setting. yeah..I know it sounds very messed up but it worked. thanks again for the help.

No probs.. It's what we are here for..

Bet you know loads about networks now eh? Anyway.. it works and that's all that matters. The joy of linux.. it might not be elegant sometinmes, or even the right way, but if it works who cares? :lol:

Feel free to ask anything else.. I'm sure we will help if we can.
