Lenovo IdeaPad Y400 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. The WiFi in your laptop, if so equipped, makes use of a wireless adapter to communicate with your home router. Searching for a new adapter is simple due to the fact that all you need to know beforehand is what OS you are running on your Lenovo IdeaPad Y400. Most new Wifi adapters are plug-n-play, in that you just plug it in the USB port and the system will install the drivers automatically.
Subtle cues of an inadequate WiFi adapter
- The WiFi adapter in your Lenovo laptop is unable to connect to the internet
- Your wireless internet connection goes in and out all the time
- The laptop wireless driver suddenly shows as uninstalled
