I'm having Roaming-Problems with 7925 Wireless Phones. The 7925 in some cases lose their connection during Layer 3 Roaming to another controller.
- 7921 Wireless Phones
- 2 WiSMs (4 4402 Controllers)
- 1142 Access-Points
- 1 Mobility Group
- Multiple AP-Groups using different Subnets
- L3 Roaming using Symetric Tunneling
To fix the problem I manually removed the client association, which deletes the mobility anchor too. The telefphone gets a new IP-Adress in the current AP-Group.
