Resolving iOS issues with Ubiquiti UniFi Access Points

This fix will work for issues where devices (primarily Apple devices) disconnect frequently, or disconnect when the screen is off and will not automatically reconnect without you going into settings and manually reconnecting. Note that each of these steps does cause reprovisioning and a few seconds of downtime will occur.

1. Login to UniFi Control Panel and click Settings
2. Go to Wireless Networks and click Edit under the SSID in question (complete this task for any SSID experiencing issues)
3. Expand 802.11 RATE AND BEACON CONTROLS
4. Uncheck Use default values and set DTIM 2G and 5G Periods to 125 (you may find that another value gives you better results depending on your setup)
5. Click Save and test

If this does not fully resolve your issue, you will most likely need to seperate the 2.4Ghz and 5GHz bands. There are multiple ways to do this, but the easiest way to do this with minimal amount of downtime for the client is to:

1. Go to Dashboard
2. Expand WLANS
3. Click pencil next to actions under each SSID you need to override and rename the SSID and select Save
4. Complete these steps for 2.4GHz and 5GHz bands
5. Once back to the Dashboard select Queue Changes, then Apply Changes under the WLANS section
