Acer Aspire 4520 wierless not working


You certainly can because apparently, it has an Acer InviLink 802.11b/g wireless LAN, Acer SignalUp technology for enhanced antenna efficiency, WI-FI CERTIFIED™

All that means is that if you aren't already seeing an icon saying your have access to wireless networks, the chip may not be turned on. Look along your Function keys for the wireless graphic icon - a circle with brackets similar to ((O)) and hit that key at the same time as the Fn key.

If there is no icon there may be a physical switch on the front of the laptop.
