Should I use WPA2, WPA or WEP network encryption on my network? You should use the strongest encryption that is compatible with your network. If your home network is compatible with WPA2 encryption, that should be your first choice. WPA2 provides the strongest protection among the three commonly-used encryptions. WPA should be your second choice if you have incompatibility issues with WPA2. WEP should be used if neither of the WPA encryption standards can be used.
