# Traversal Cloud

After enabling the **Traversal Cloud**, you can access and control the WiFi extender anytime, anywhere, on a web browser. It offers the easiest way to look over your networks. No public IP address and DDNS configuration is required. **It’s completely free!**

A web proxy is pre-built in the firmware. The traversal cloud is turned off by default. You can follow the below steps to enable it.

1. Log in to the admin, go to `Services` > `Traversal Cloud`.
2. Click the checkbox `Enable`, then click the button `Save & Apply`.
3. Now you can access your extender at the `Cloud Address` on a web browser

Recommended to set up a strong extender password (go to `System` > `Administration`) before enabling the traversal cloud.
{% endhint %}

If unable to access the cloud address, please check the below factors.

1. Please ensure the traversal cloud has been **enabled**. After enabling the checkbox, please click the `Save & Apply` button.
2. Before accessing the traversal cloud server, the extender must have an Internet connection. Please check the Internet connection on the router.
3. If you once turned off the traversal cloud function within a power cycle, please reboot the extender to refresh the traversal connection session.

&#x20;**\*\*\* REMINDER \*\*\***

The traversal cloud is relayed on the carrier's gateway. Some carriers might block the traversal technology. We do not 100% ensure the cloud address works perfectly. The traversal cloud is provided for free, and it's not involved in the extender quality or working performance.
