Acer Aspire EC-471G Wifi
A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the system will install the drivers automatically. It will be easier to buy a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. Buying a USB wireless adapter is quick and painless because the only thing you have to know is what OS you are running on your Acer laptop. The WiFi in your laptop, if so equipped, uses a piece of hardware in order to talk to your router.
Clues to watch for to know the wireless card has very little life left
- The laptop wireless driver suddenly shows as uninstalled
- Your WiFi signal disconnects itself throughout the day
- The wireless adapter on your laptop cannot see the SSID coming from your router
