Data Rate Won't Exceed 54 Mbps When WEP or TKIP Encryption is Configured
What is the problem?
Client device's Wi-Fi data rate will not exceed 54 Mbps when wired equivalent privacy (WEP) or temporal key integrity protocol (TKIP) encryption is configured.
What is causing the problem?
The IEEE* 802.11n draft prohibits using high throughput with WEP or TKIP as the unicast cipher. If you use these encryption methods (for example, WEP, WPA-TKIP), your data rate will drop to 54 Mbps. The latest Intel® Wireless Adapter client drivers connect using a legacy IEEE 802.11g connection rather than failing to connect altogether, which complies with the IEEE 802.11n draft.
Solution:
- Contact your Wi-Fi access point (AP) or router manufacturer to download the latest firmware version, or get information on particular models supporting High Throughput.
- Disable packet bursting or similar features
- Configure the Wi-Fi client device's profile to use Wi-Fi Protected Access* (WPA2-AES or WPA2-TKIP).
- Configure the AP or router to match the client profile.
| Note | Some AP or router manufacturers may not have updated firmware solutions for devices sold outside of the United States. |
