Sony VGN-SZ440 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. Most new Wifi adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there. The WiFi in your laptop, if so equipped, makes use of a wireless adapter to communicate with your wireless router or modem. Searching for a new adapter is simple because all you need to know is what OS you are running on your Sony laptop.
Easy warnings the WiFi adapter will have to be replaced
- The wireless adapter driver shows it as not installed
- The WiFi adapter on your laptop does not connect at all
- The WiFi drops multiple times over and over again
