Hello,
Yesterday my laptop (lenovo z580) dropped wi-fi connection. My computer stopped recognising the wireless device. I tried updating my Intel PROSet to the newest version, hoping it would install the newest driver, but nothing changed.
In the device manager, in the tab with network cards, the Intel Centrino Wireless-N 2200 is shown as a "hidden" device and in properties it shows up as "device not connected to the computer (code 45). I didn't open the case, so I couldn't disconnect anything.
I'm using Windows 8.1 Pro. The driver that shows up in the device's properties is 15.10.0.15. I tried updating the driver also via the drivers tab in properties but nothing happened. I also tried restoring system to the restoration point made about a week ago, when the device worked okay, but it also didn't help anything.
What else can I do to try and fix the problem? Is it software or hardware issue?
