Lenovo ThinkPad L412 Wifi
You are better off buying a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the system will install the drivers automatically. Finding a WiFi adapter is easy because the only thing you have to know is what OS you are running on your Lenovo laptop. The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your wireless router or modem.
Some warnings the wireless card needs replacing
- The WiFi adapter driver gives errors when installing
- The WiFi drops for no reason over and over again
- The WiFi adapter in your Lenovo laptop cannot see the SSID coming from your router
