Sony VPCZ1390L Wifi
It is cheaper and easier to purchase a new USB adapter and install it, than to replace any built-in adapter your laptop may have. WiFi, or wireless internet, makes use of a wireless adapter to communicate with your wireless router or modem. Searching for a new adapter is simple because the only thing you have to know is the operating system that is installed on your laptop. Most USB wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will handle everything from there.
Symptoms your internal WiFi is in need of replacing
- The laptop wireless driver suddenly shows as uninstalled
- Your WiFi signal goes in and out over and over again
- The wireless adapter in your Sony laptop does not connect at all
