I got a new Lenovo IdePad Z570 for Christmas and it's brilliant. However, it has internet connection problems. Even though I sit in the same room where the router is, sometimes Lenovo just refuses to connect with the internet and when it does, the connection just stops after a couple of minutes. Also, when I take it upstairs, even though it says that the signal strength is excellent, it doesn't connect. Is there anything I could do with it or should I just call Lenovo and give the laptop back to them, so that they can repair it? Thanks for help.
