Sony VPCEA3JGX Wifi
You are better off buying a new wireless USB adapter and install it, than it is to replace any type of OEM adapter you might have. The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your wireless router or modem. A lot of newer wireless adapters are plug-n-play, which means you simply plug it into a USB port and the OS will handle everything from there. Finding a WiFi adapter is easy because the only thing you have to know is the operating system that is installed on your Sony VPCEA3JGX.
Simple indications poorly running onboard WiFi
- The wireless adapter driver cannot be installed
- Your WiFi signal has trouble connecting all the time
- The wireless adapter on your laptop is unable to connect to the internet
