Lenovo ThinkPad X201 Wifi
You are better off buying a new 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 operating system that is installed on your laptop. Most USB wireless adapters are simply plug and play, which means you simply plug it into a USB port and the system will install the drivers automatically. The WiFi in your laptop, if so equipped, uses a piece of hardware in order to connect to your wireless router or modem.
Clues to watch for to know your internal WiFi is on its last leg
- The laptop wireless driver gives errors when installing
- The wireless signal disconnects and reconnects every day
- The wireless adapter on your laptop is unable to connect to the internet
