I recently moved into a new apartment, and took my Dell Inspiron 15R (Windows 7, 64 Bit) with me. After a while of normally using the laptop and the internet, I noticed that my network status had changed to limited internet connectivity. I tried disconnecting and reconnecting to the network, but soon realized that my Wireless Network Connection was disabled. When I tried reactivating my Centrino Wireless 2230 Adapter (it got deactivated somehow) I got a Blue Screen and my laptop rebooted. After logging in, I noticed that my Network Adapter was still deactivated, however, activating it was not an issue, and everything worked fine for a few hours.
Then, the same problem: limited internet connectivity. I tried manually deactivating the Network Adapter (in the Device Manager), but I again got a blue screen/crash/reboot. The same thing (blue screen, etc.) also happens when I want to put my laptop in stand-by mode (I assume this disables the Network Adapter as well).
Since the only thing I changed was the phsyical location of my laptop (I moved) and the network I connect to, I assume that the problem has something to do with the Network Adapter, but I have no idea what it is. Help will be greatly appreciated!
