Sorry for the late reply but I find my friend who knows the problem and he helped me. The problem was bad configured network... thank you guys anyway for the fast reply from everyone. Have a nice time...
I try that but it doesn't working. I try to put the IP on my router in browser and it can't connect with router (to give the user name and pass for entry). I have Windows XP on the same computer (dual boot) and the XP has good connection on internet but not with Mandriva.
I can't connect on internet via router. I am new on Mandriva and I had PPPoE connection before, all worked fine but now I have router and I don't know how to configure my network to work via router. Any help will be apriciated
