Sony VGN-BX540BW Wifi
It is cheaper and easier to purchase a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. A lot of newer wireless adapters are plug-n-play, which means you simply plug it into a USB port and the system will install the drivers automatically. WiFi, or wireless internet, uses a piece of hardware to communicate with your wireless router or modem. Buying a wireless adapter is quite easy because the only thing you have to know is the operating system that is installed on your laptop.
Some clues of a weakening wireless card
- Your wireless internet connection disconnects and reconnects all the time
- The WiFi adapter driver shows it as not installed
- The WiFi adapter in your Sony laptop does not connect at all
