Sony VPCEA46FM Wifi
The WiFi in your laptop, if so equipped, uses a piece of hardware to communicate with your home network. Finding a WiFi adapter is easy because the only thing you have to know is the operating system that is installed on your Sony VPCEA46FM. You are better off buying a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. A lot of newer wireless adapters are simply plug and play, which means you simply plug it into a USB port and the system will install the drivers automatically.
Some warnings of a worsening wireless card
- The WiFi adapter driver suddenly shows as uninstalled
- Your WiFi signal disconnects itself throughout the day
- The wireless adapter on your laptop is unable to connect to the internet
