Sony VGN-AR570E Wifi
WiFi, or wireless internet, uses a piece of hardware to send and receive signals to and from your wireless router or modem. It will be easier to buy a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. 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-AR570E. 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.
Key clues of an inadequate WiFi adapter
- Your WiFi signal drops for no reason over and over again
- The wireless adapter on your laptop cannot see the SSID coming from your router
- The laptop wireless driver gives errors when installing
