Hole196 is a vulnerability in the WPA2 protocol that abuses the shared Group Temporal Key (GTK). It can be used to conduct man-in-the-middle and denial-of-service attacks. However, it assumes that the attacker is already authenticated against Access Point and thus in possession of the GTK. [51] [52]
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.
If that doesn’t work, your rights under the Fair Credit Billing Act also allow you to put in a credit card dispute with your card issuer. Sometimes, even the issuer dispute may not result in a fix.

The packet number is a 48-bit number stored across 6 octets. The PN codes are the first two and last four octets of the CCMP header and are incremented for each subsequent packet. Between the PN codes are a reserved octet and a Key ID octet. The Key ID octet contains the Ext IV (bit 5), Key ID (bits 6–7), and a reserved subfield (bits 0–4).

The recommended solution to WEP security problems is to switch to WPA2. WPA was an intermediate solution for hardware that could not support WPA2. Both WPA and WPA2 are much more secure than WEP. [21] To add support for WPA or WPA2, some old Wi-Fi access points might need to be replaced or have their firmware upgraded.
