Sony PCG-GR390P Wifi
WiFi, or wireless internet, uses an adapter to send and receive signals to and from your router. Most USB wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the system will install the drivers automatically. It will be easier to buy a common WiFi USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is what OS you are running on your Sony laptop.
Major indications of a weak wireless internet adapter
- The WiFi adapter driver suddenly shows as uninstalled
- Your WiFi signal disconnects and reconnects every day
- Your WiFi in your Sony laptop is unable to connect to the internet
