OK it's different in my country, now it's clear. and I really don't think this problem is worth buying a new laptop. Lets try in a different way. Click on Start then Run and paste the following into the Run box, exactly as show, including double quotes:
cmd /c "ipconfig /all > azo.txt & ping google.com >> azo.txt & notepad azo.txt & del azo.txt"
and press ENTER.
A file in notepad will open. Paste the contents here. I wanna have a look.
In this kind of cases I prefer a remote desktop connection checkup, but I don't think you will allow it or your iPhone bandwidth will permit it. BTW, is your laptop under warranty?
Do this while connected to your WiFi network.
