Saab,
Thanks for the reply.Yes I've used this laptop before but now I'm getting this problem.It started when someone configured it to my wireless network in my home.Regarding to your questions, I set it to automatically find the IP address.
I don't know anything about the rest of information you required.Sorry
I went tools menu, than lan settings and checked automatically detect settings, but is still not working.
When I use a cable to connect it works perfectly!!!
Thanks
