Disable Multicast Firmware Upgrade
There might be network configurations in which you cannot use multicast. If you disable
multicast on the AP Upgrade Setting screen, the firmware upgrade process uses unicast,
which is a slower process because the firmware upgrade is applied to groups of access
points instead of simultaneously to all access points. The time that the unicast firmware
upgrade process takes depends on the network load and on the type of Ethernet interface to
which the wireless controller is connected.
 To disable multicast firmware upgrade for access points:
1. Open a web browser. In the browser’
s address field, type the wireless controller’s IP
address.
By default, the IP address is 192.168.0.250.
The wireless controller’s login screen displays.
2. Enter your user name and password.
If you did not yet personalize your user name and password, enter admin for the user
name and password for the password, both in lowercase letters.
3. Click the Login button.
The wireless controller’s web management interface opens and displays the Summary
screen.
4. Select Maintenance > Upgrade >
AP Upgrade Settings.
The AP Upgrade Settings screen displays.
5. Clear the Enable Multicast check box.
This check box is selected by default.
6. Click the Apply button.
