Upgrading Slave Access Points

When the GWN76XX is being paired as slave using another GWN76XX Access Point acting as Controller, users can upgrade
their paired access points from the GWN76XX Master Controller.
To upgrade a slave access point, log in to the GWN76XX acting as Master Controller and go to Access Points.
Make sure that firmware server path is set correctly under Maintenance, check the desired APs to upgrade, and click on
to upgrade the selected paired access points.

Sequential Upgrade

If you choose multiple slave devices to upgrade their firmware, two options are available: "All-at-Once" and "Sequential". "All-
at-Once" will use the default method, all checked slaves will upgrade their firmware at the same time, while using "Sequential"
upgrade method, the slaves will upgrade their firmware one by one in order to:
Avoid entire Wi-Fi service interruption by full system firmware upgrade.
Reduce network bandwidth consumption caused by firmware downloading.
