Lenovo IdeaPad P400 Wifi
Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is the current operating system on your Lenovo IdeaPad P400. A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the system will install the drivers automatically. WiFi, or wireless internet, uses an adapter in order to talk to your router and modem. It is cheaper and easier to purchase a new USB adapter and install it, than to replace any built-in adapter your laptop may have.
Elements to watch for in a failing wireless internet adapter
- The wireless adapter driver cannot be installed
- The wireless signal disconnects itself during the day
- The wireless adapter on your laptop will not connect to your router anymore
