Removal of TKIP Encryption to Speed up osuwireless

Advanced Encryption Standard (AES) replaced Temporal Key Integrity Protocol (TKIP) as the preferred Wi-Fi encryption method in June 2004. OCIO has been supporting both AES and TKIP encryption for osuwireless, but will be doing away with TKIP at midnight on December 20. After that time, users will no longer be able to connect to osuwireless using TKIP.

Why are we doing this?

Clients using TKIP communicate more slowly to wireless access points, which in turn slows down performance for all clients using the same wireless access point. Currently, less than 0.3% of osuwireless clients use TKIP. Removing TKIP will ensure better performance for all users of the network.

What do those using TKIP need to do?

If you have been identified as using TKIP on one of your devices, follow these steps to update your settings:

  1. Make sure that your device’s wireless network driver is up-to-date. If drivers available for the device do not support AES, you will need to get a new wireless network adapter.
  2. Run our wireless configuration utility.
  3. Manually check the network settings to ensure your device is using AES and update if needed.

If after running through these steps, you still need assistance with your device, you may visit one of our BuckeyeBar locations and our staff will be happy to help.
