Lenovo ThinkCentre 7638 Wifi
WiFi, or wireless internet, uses an adapter to send and receive signals to and from your router and modem. It is cheaper and easier to purchase a new USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. Most USB wireless adapters are plug-n-play, which means you simply plug it into a USB port and the OS will install the drivers on its own. Searching for a new adapter is simple because all you need to know is the current operating system on your desktop.
Clues to watch for to know your internal WiFi will not live much longer
- The WiFi adapter in your Lenovo desktop cannot see the SSID coming from your router
- The wireless signal disconnects itself every day
- The wireless adapter driver cannot be installed
