DD-WRT firmware and Cloud4Wi


[Please note that this article refers to an older version of the product and may be outdated. You can find the most recent guide here]

Many access points support the DD-WRT firmware, and this allows you to use Cloud4Wi even if the original firmware of your product does not directly support Cloud4Wi.

To find out if a specific router is supported and which file you need to download to install DD-WRT on it, please check here on DD-WRT website:


This guide shows how to configure a device running the firmware DD-WRT, in order to use each single Access Point as a HotSpot.

Please note that the images contained in this article may contain outdated configuration data. Therefore, please check the data contained in the article "Parameters for the Solution" at the bottom of the page, as they are certainly up to date.


It is mandatory that the device supports any stable version of DD-WRT including Chillispot. For any information about supported versions, please refer to Is my router compatible with DD-WRT and Cloud4Wi?.

If you have a supported firmware available, then the following conditions are required:

  • Connect the device to the Internet
  • The WiFi interface is enabled
  • The DHCP server for WiFi clients must be disabled

Accessing the AP

Please access the device through the web interface.


Wireless interface configuration

As the first step of the configuration, through the Wireless > Basic Settings menu it is necessary to make sure that the WiFi interface is enabled.

Any WiFi access encryption should be disabled, since in the Hotspot scenario the authentication is performed through the RADIUS server. This can be done through the Wireless > Wireless Security menu.

To end this configuration, it is necessary to set the value Unbrigded for the network corresponding to the interface chosen.
This can be done through the Setup > Networking Security menu.


Hotspot configuration

The last step of the procedure is opening the Services > Hotspot menu to configure the WiFi device as a HotSpot. Here it is necessary to enable Chillispot, and then specify the RADIUS server details, the Splash Portal URL, the Radius NAS ID, and in some cases the interface that Chillispot will use for the Hotspot.
The Radius NAS ID parameter set in the device must be unique for all the Hotspots belonging to your network. Otherwise the HotSpot will not be correctly integrated with the Solution.


Walled Garden

This feature makes it possible to configure the Walled Garden. The following articles are available for more information:


Allowing free access to the CDN

As explained in the article Improving the performance of Control Panel and Splash Portal by enabling the CDN, it is necessary to add some IP addresses to the Walled Garden in order to support the access to the CDN.
The IP addresses to add for this purpose are:


Retrieving the identifier for the Control Panel

To integrate the Access Point with the Solution, you msut enter its details into the Control Panel.

To get further information on how to do that, please see How to add a Hotspot. Secondly, in the Control Panel, a field called Identifier will be required by the web interface. For DD-WRT, as said before, it corresponds to the RADIUS NAS ID value that has been configured in Services > Hotspot, in the Chillispot section.

Parameters for the Solution

The parameters indicated above for the Mode Settings section are mandatory for the proper functioning. The parameters to integrate the device with the Solution are the following:

Primary Radius Server IP/DNS
Backup Radius Server IP/DNS:
Redirect URL: https://splashportal.cloud4wi.com/
Shared Key: (it will be communicated by Cloud4Wi)

Please note that it is necessary to enter the Splash Portal URL exactly as it is written above.
If you enter the Splash Portal URL in different formats (e.g. https://splashportal.cloud4wi.com/c4wportal/mysplashportal), then the redirection to the Splash Portal will fail and the end-user will not be able to see the Splash Portal.

If these parameters change in the future, we will promptly inform you about new values.
