One is poor configuration and the other is poor encryption. Two types of vulnerabilities can be found in the Wireless LAN. But in ad hoc networks, there is no access point each node connects in a peer-to-peer way. Infrastructure networks have one or more access points that coordinate the traffic between the nodes. Wireless networks are based on IEEE 802.11 standards defined by the Institute of Electrical and Electronics Engineers (IEEE ) for ad hoc networks or infrastructure networks.
