Ideapad Z570 Wifi & Lan problem

[Ajjish]

I have purchased Z570 i5-2410M Intel second generation   ... 1month back

I have a problem related to WIFI.  As soon as my win7 boots and wifi try to connect suddenly blue screen appears and get shutdown . or some delays the start by 5 min .Same problem with LAN (ethernet) also. In my system atheros wifi driver is installed which i think creates the problem. 

What is the issue ... can anyone tell me ....

I have seen the Drivers & download section of lenovo, there now four driver r given in Networking: Wireless LAN section for win7 & three for xp. Which one driver is suitable for my laptop or i have to install all. Plzz Reply fast.

you need to install the one for your wireless adapters. check your receipt or the box, it should be an information which model of wireless adapter you have.

or you can try to install drivers one by one. if you don't install the correct drivers, you'll get an error.

can you check if the issue persists on safe mode?
( press f8 to load safe mode when you see lenovo logo at start-up )

also, from the same place, try to load "last known good configuration" it may help.
