Additional information:

- All URLs use HTTPS. This assumes your device(s) are running 3.7.56 or later and that the device's date is properly set. Please change URLs to HTTP for device(s) running earlier firmware or if the date is incorrect (e.g. if device can't reach a NTP server).

Instructions:

- All URLs use HTTPS. This assumes your device(s) are running 3.7.56 or later and that the device's date is properly set. Please change URLs to HTTP for device(s) running earlier firmware or if the date is incorrect (e.g. if device can't reach a NTP server).
- You may start to see EVT_AP_RestartProc events in the controller log. If you see these, please report if there is anything specifically in your setup that triggers the events. The processes restarting is not new, but the reporting of the restarting is, and we are using these reports to clean up these issues.
- US-XG-6POE upgrading from 4.0.2 or earlier will take a long time to upgrade. Don't be surprised if your switch is unavailable for 5-10+ minutes as 4.0.3+ also updates the PoE firmware to improve PD compatibility.
- UIS-8-450W upgrading from 4.0.33 and earlier will have their PoE firmware upgraded automatically to improve PD compatibility. That process will take a few minutes. PoE will be unavailable during the upgrade process.
- USW-16/24-PoE running 4.0.44 cannot directly upgrade to firmware 4.0.60 or later. Please upgrade to THIS release first via custom upgrade and then you'll be able to upgrade it to firmware 4.0.60+.

About Access Point Firmware:

If you update the Access Point (AP) firmware, your device can benefit from changes that fix multiple issues encountered by wireless clients, correct different user interface problems, add various functionalities, and include support for newly developed protocols.

Before performing this task, we recommend that you read and understand all the installation steps, because there are many AP models and manufacturers available. Each producer strives to make the procedure as simple as possible, but there are cases when it's anything but that.

It is also advisable that you apply a new access point firmware in a steady power environment (UPS unit will satisfy this need), using an Ethernet cable rather than a wireless connection. The latter can be easily interrupted.

With this in mind, if you wish to apply this version, click the download button and install the package on your access point. Remember to check back with our website as often as possible so that you don't miss a single new release.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
