# Upgrade

## What should we do if it prompts you "failed to upgrade" or "upload failure"?

1. Please double check whether the network connection is normal;
2. Please select the device(s), click "Cancel" and then click "Upgrade" again;

## What should we do if it's failed to detect the encoder via Device Manager after upgrading?

1. Please double confirm whether the encoder can be powered on and running;
2. Please manually add one more IP for your PC under the same network segment 1 like 192.168.<mark style="color:red;">**1**</mark>.XXX, or else it might cause upgrade failure.
3. Please follow below steps to upgrade the firmware again if 1st is confirmed:

* Run Device Manager if you already installed the latest version;
* Go to Configuration->Change HTTP Port from 80 to <mark style="color:red;">**6868**</mark>;
* Click Manual Add->Select the device you just manually added;
* Browse the Latest & correct firmware->Enter User Name and Password->Click "Upgrade"
* The device will be reboot and you can try to search the device later;
* If failed to upgrade, please try to connect it to your PC with ethernet cable and try again;
