Lenovo M490S Wifi
The WiFi in your laptop, if so equipped, uses an adapter to send and receive signals to and from your router and modem. Most USB wireless adapters are plug-n-play, which means you simply plug it into a USB port and the operating system will take care of the rest. Buying a USB wireless adapter is quick and painless because all you need to know is the operating system that is installed on your laptop. It will be easier to buy a new USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have.
What are the signs that the wireless card has to be replaced?
- Your WiFi signal goes out randomly during the day
- The laptop wireless driver suddenly shows as uninstalled
- The wireless adapter in your Lenovo laptop is unable to connect to the internet
