My laptop did an update and it wont connect to the internet. It works when I plug it into the ethernet, however I need to take it with me. The wireless switch is on and has been on. I have tried restarting it and nothing changed. Went into the control panel and tried updating the wireless adapter and it says it's up to date. On the Intel wifi link next to it there is a yellow exclamation point and when I click it it gives me error code 52. Windows cannot verify the digital signature for the drivers required for this device. Please help.!!
