It will be easier to buy a new wireless USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. Finding a WiFi adapter is easy due to the fact that all you need to know beforehand is the operating system that is installed on your laptop. A lot of newer wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there. The WiFi in your laptop, if so equipped, uses an adapter in order to connect to your home router.
Major signs the wireless card should need replacing
- The wireless adapter in your Sony laptop cannot see the SSID coming from your router
- The wireless adapter driver cannot be installed
- Your WiFi signal disconnects itself throughout the day
