Sony VGN-TXN25N-B Wifi
The WiFi in your laptop, if so equipped, uses a piece of hardware to communicate with your router and modem. 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. Most new Wifi adapters are simply plug and play, in that you just plug it in the USB port and the OS will install the drivers on its own. Buying a wireless adapter is quite easy because all you need to know is the operating system that is installed on your laptop.
What warnings should I watch out for to know if my wireless card needs to be replaced?
- Your WiFi signal goes out randomly over and over again
- The wireless adapter in your Sony laptop is unable to find a signal from your router
- The laptop wireless driver shows it as not installed
