Due to extra security around Clover Mobile and Clover Mini devices, Clover Mobile and Clover Mini will be compatible with WPA2 networks. They will not be compatible with WEP networks.
How can I tell if my network is WEP vs. WPA2?
If you have an Windows OS computer, view “Wireless Network Connect” to view your wireless networks. Each wireless network will designate whether they are a WPA2 network or not.
If you have a Mac OS computer, view “Network”, click Advanced… and find the network name of interest. The type of network will display under “Security”.
