Lenovo ThinkCentre 2491 Wifi
Most new Wifi adapters are plug-n-play, which means you simply plug it into a USB port and the system will install the drivers automatically. 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 desktop. WiFi, or wireless internet, uses an adapter in order to talk to your wireless router or modem. You are better off buying a new USB adapter and install it, than to replace any built-in adapter your desktop may have.
Clues to watch for to know your internal WiFi is on its last leg
- Your WiFi on your desktop is unable to connect to the internet
- Your WiFi signal has trouble connecting every day
- The wireless adapter driver suddenly shows as uninstalled
