Sony VGN-TZ240N Wifi
It will be easier to buy a new 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 an adapter to send and receive signals to and from your wireless router or modem. Buying a USB wireless adapter is quick and painless because the only thing you have to know is the current operating system on your Sony VGN-TZ240N. Most new Wifi adapters are simply plug and 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.
Important clues to watch for in a failing wireless card
- The laptop wireless driver shows it as not installed
- The WiFi adapter on your laptop does not connect at all
- The wireless signal has trouble connecting every day
