Lenovo G400S 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 new Wifi adapters are simply plug and play, which means you simply plug it into a 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 home router. Buying a wireless adapter is quite easy because the only thing you have to know is what OS you are running on your Lenovo laptop.
Simple signals your wireless internet adapter needs replacing ASAP
- The WiFi adapter on your laptop is unable to find a signal from your router
- The laptop wireless driver cannot be installed
- The wireless signal has trouble connecting throughout the day
