Sony VGN-TT290N Wifi
Buying a USB wireless adapter is quick and painless because all you need to know is what OS you are running on your laptop. The WiFi in your laptop, if so equipped, makes use of a wireless adapter to send and receive signals to and from your home network. It will be easier to buy a common WiFi USB adapter and install it, than it is to replace any type of OEM adapter you might have. Most USB wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will install the drivers on its own.
What are the clues to watch out for to know my wireless internet adapter is not working properly?
- Your wireless internet connection drops multiple times throughout the day
- Your WiFi in your Sony laptop is unable to find a signal from your router
- The WiFi adapter driver shows it as not installed
