WEP WIFI Protocol is Not Secure
If you log on to a WIFI network that is using either WEP (Wired Equivalent Privacy) or TKIP (Temporal Key Integrity Protocol), you should be notified by Windows 10 that the network is not secure.
While the WEP protocol dates from 1999, internet service providers may still use it by default on routers. WEP encryption can be broken in a few minutes. One of its key shortcomings is its use of the same key for long periods of time for devices on a network.
TKIP has some of the same weaknesses that WEP does since it uses some of the same elements.
