WPA-Personal and WPA2-Personal remain vulnerable to password cracking attacks if users rely on a weak password or passphrase. WPA passphrase hashes are seeded from the SSID name and its length; rainbow tables exist for the top 1,000 network SSIDs and a multitude of common passwords, requiring only a quick lookup to speed up cracking WPA-PSK.

In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used. [ 1 ] Key
The Wi-Fi Alliance refers to their approved, interoperable implementation of the full 802.11i as WPA2, also called RSN (Robust Security Network). 802.11i makes use of the Advanced Encryption Standard (AES) block cipher, whereas WEP and WPA use the RC4 stream cipher.
Both WPA and WPA2 support EAP authentication methods using RADIUS servers and preshared key (PSK). The number of WPA and WPA2 networks are increasing, while the number of WEP networks are decreasing, [34] because of the security vulnerabilities in WEP. WPA2 has been found to have at least one security vulnerability, nicknamed Hole196.
A major security flaw was revealed in December 2011 that affects wireless routers with the WPS PIN feature, which most recent models have enabled by default. The flaw allows a remote attacker to recover the WPS PIN in a few hours with a brute-force attack and, with the WPS PIN, the network's WPA/WPA2 pre-shared key (PSK). [3]
Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware.
Firewall and Antivirus Filters This field lets you know that PRIVATE WiFi’s free firewall (Netfilter) and antivirus software (ClamAV) is turned on. Keep in mind that our protection is only effective when PRIVATE WiFi is activated. Change Location This drop-down menu allows you to change the server location you are accessing.
