Some devices with dual-band wireless network connectivity do not allow the user to select the 2.4 GHz or 5 GHz band (or even a particular radio or SSID) when using Wi-Fi Protected Setup, unless the wireless access point has separate WPS button for each band or radio; however, a number of later wireless routers with multiple frequency bands and ...
Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network.
The Wi-Fi Alliance standardized these methods as Wi-Fi Protected Setup; however, the PIN feature as widely implemented introduced a major new security flaw. The flaw allows a remote attacker to recover the WPS PIN and, with it, the router's WPA/WPA2 password in a few hours. [ 45 ]

A successful ARP spoofing (poisoning) attack allows an attacker to alter routing on a network, effectively allowing for a man-in-the-middle attack.. In computer networking, ARP spoofing (also ARP cache poisoning or ARP poison routing) is a technique by which an attacker sends Address Resolution Protocol (ARP) messages onto a local area network.
Router2 manages its attached networks and default gateway; router 3 does the same; router 1 manages all routes within the internal networks. Accessing internal resources If PC2 (172.16.1.100) needs to access PC3 (192.168.1.100), since PC2 has no route to 192.168.1.100 it will send packets for PC3 to its default gateway (router2).

A special case of private link-local addresses is the loopback interface. These addresses are private and link-local by definition since packets never leave the host device. IPv4 reserves the entire class A address block 127.0.0.0 / 8 for use as private loopback addresses. IPv6 reserves the single address ::1.
