My wireless worked perfectly until yesterday, i have been trying to fix it but... I have a dell inspiron 15r, first off, its not searching for wireless networks, secondly when i diagnose it, it says it cant install my wireless adapter, but when i check it under device manager, it says there is no problem with the device, and that it is installed and updated, also, this may not be relevant but, i had been hearing a shaking from inside my laptop recently, and yesterday i took off my battery and a small metal clip fell from the area behind the access panel, but i dont know whats behind there... sorry if i explained this badly, any help?
