Open issues

• Improving false radar detection in Cisco Catalyst 9105 Series APs, Cisco Catalyst 9115 Series APs, and Cisco Catalyst 9120 Series Aps
• The controller does not send the correct association ID (AID), causing APs to reject new client associations.

• Cisco Catalyst 9130 Series high channel utilization and client lags with 9 or more clients using MS Teams.

• Cisco Catalyst 9130 Series APs drop packets on air, for the Phoenix WinNonlin application.

• Cisco Catalyst 9120 Series APs show a high client count while the neighboring APs have very few clients associated

• Tx power for Microcell created by AP for slot 2 of Cisco Catalyst 9130 Series AP

• Cisco Catalyst 9115 Series APs report DFS on channels incorrectly

• Cisco Catalyst 9130 AP causes unexpected fragmentation of packets when using data encryption

• Cisco Catalyst 9115 AP displays CAC behavior when it moves to another wireless controller
