Sony PCG-FRV25 Wifi
Most new Wifi adapters are plug-n-play, which means you simply plug it into a USB port and the OS will handle everything from there. It is much simpler to buy a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses a piece of hardware in order to talk to your router and modem. Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is the current operating system on your Sony laptop.
Indications to watch for in a bad wireless internet adapter
- The WiFi drops for no reason all the time
- The WiFi adapter driver suddenly shows as uninstalled
- Your WiFi in your Sony laptop will not connect to your router anymore
