One of our laptops is a Sony Vaio, about 5 years old. Recently, it started having an issue where it will disconnect from the wireless router. None of the other laptops are doing this, nor is the PC.
Is it likely that the internal wireless card has just gone toes up? Is this fixable or is it better to just scrap the laptop for a new one?
Thanks!
