Apple PowerBook 540C Wifi
Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is what OS you are running on your Apple laptop. It is much simpler to buy a common WiFi USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses an adapter in order to connect to your router. 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.
Major clues your wireless internet adapter will have to be replaced
- Your WiFi on your laptop cannot see the SSID coming from your router
- The wireless adapter driver suddenly shows as uninstalled
- Your wireless internet connection goes in and out during the day
