Lenovo ThinkCentre 3491 Wifi
You are better off buying a new wireless USB adapter and just plug it in, than to replace any built-in adapter your desktop may have. Searching for a new adapter is simple because all you need to know is what OS you are running on your Lenovo desktop. Most USB wireless adapters are simply plug and play, which means you simply plug it into a USB port and the operating system will take care of the rest. The WiFi in your desktop, if so equipped, uses a piece of hardware in order to talk to your home router.
Important clues of a worsening onboard WiFi
- The wireless adapter in your Lenovo desktop will not connect to your router anymore
- The wireless adapter driver suddenly shows as uninstalled
- The wireless signal disconnects and reconnects throughout the day
