Sony VGN-TT250N Wifi
You are better off buying a new USB adapter and install it, than it is to replace any type of OEM adapter you might have. Finding a WiFi adapter is easy because all you need to know is the current operating system on your laptop. 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. The WiFi in your laptop, if so equipped, uses a piece of hardware to communicate with your wireless router or modem.
Main clues the WiFi adapter is in dire need of a replacement
- Your wireless internet connection goes out randomly every day
- Your WiFi in your Sony laptop cannot see the SSID coming from your router
- The wireless adapter driver gives errors when installing
