Sony PCG-NV109M Wifi
It is much simpler to buy a common WiFi USB adapter and just plug it in, than it is to replace any type of OEM adapter you might 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. The WiFi in your laptop, if so equipped, uses an adapter in order to connect to your router and modem. Buying a wireless adapter is quite easy because the only thing you have to know is the current operating system on your Sony laptop.
Indications to watch for in a bad wireless card
- The WiFi adapter in your Sony laptop will not connect to your router anymore
- The wireless adapter driver gives errors when installing
- The WiFi disconnects and reconnects throughout the day
