Sony VGN-C291 Wifi
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. The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to talk to your home network. It will be easier to buy a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. A lot of newer wireless 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.
Major indications the wireless card should need replacing
- The WiFi adapter driver suddenly shows as uninstalled
- The wireless signal disconnects and reconnects every day
- Your WiFi in your Sony laptop does not connect at all
