Sony VGN-CR590 Wifi
It is cheaper and easier to purchase a new wireless USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to connect to your home network. Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is what OS you are running on your Sony laptop. 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.
Symptoms of an unhealthy wireless card
- The wireless adapter driver suddenly shows as uninstalled
- The wireless adapter in your Sony laptop is unable to find a signal from your router
- The WiFi disconnects itself every day
