Updating Wi-Fi Settings
One of the first recommendations made to users of the REV Control System is to update Wi-Fi settings, specifically the name and the password.
All Control Hub's come with a default network name and password. It is useful to change the name and password especially in environments where there are multiple Control Hubs running like at an event or in a classroom. Changing from the default adds an element of network security to the Hub by reducing the potential for access from outside sources.
The Control Hub (REV-31-1595) can utilize either the 2.4 GHz or 5 GHz Wi-Fi band. REV Robotics advises that during competition teams utilize a 5 GHz channel for robot communication. Consult the table below for Driver Station devices that can operate on the 5 GHz band.
Supported Android Devices and Wi-Fi Band Capabilities
As of the 2024-2025 FTC season, Android phones must be running Android 7 (Nougat) or newer to be compatible with the Driver Station App. Please check the game manual for full rules.

The following section will highlight how to access and make changes within the Wi-Fi settings. This section will use the REV Hardware Client to showcase how to make these changes. Once a user has connected to the Robot Controller Console, either via the Hardware Client or a web browser, the steps for accessing Wi-Fi settings are the same.
The following steps assume that users have already connected to the Robot Controller Console. Please go to the Connect to the Robot Controller Console if this is not the case.
Steps to Updating Wi-Fi Settings
While in the Robot Controller Console select the menu button. In the image below the menu button is highlighted by an orange square in the upper right-hand corner.
When the menu opens, select Manage.
The Manage page is where the Wi-Fi Settings live. The following steps will show and discuss each change as it is made. Please keep in mind the following warning while moving through the steps:
You will need to reconnect to the new Wi-Fi network after changing the name and/or password. This is true for any Wi-Fi connection, but if you are accessing the REV Hardware Client via a USB connection the Hub will stay connected. Though, you may need to close and reopen the Hardware Client in order to see the changes.
Not all aspects of the Wi-Fi settings need to be changed. If you need to change name and password and do not need to mess with the Wi-Fi band or channel, leave those settings at default, and click Apply Wi-Fi Settings.
Changing Control Hub Name
Under Wi-Fi Settings, there is an option to change the name of the Control Hub.
It is useful to change the Control Hub name to something unique, especially in environments where there are multiple Control Hubs running like at an event or in a classroom.
For FTC teams you will want to change the name from the default to team number - RC. (i.e. 99999-RC)
Changing the Control Hub Password
Under Wi-Fi Settings, there is an option to change the password of the Control Hub. There are not any restrictions on the password. Changing it from the default is advised but it does not have to change to anything complicated.
The default password 'password' is a well know password by Control Hub users, since it is the default for all Control Hubs. Staying with the default password significantly reduces network security. Changing from the default adds the element of network security back to the Hub by reducing the potential for access from outside sources.
Changing the Wi-Fi Band and Channel
The Control Hub is capable of utilizing either the 2.4 GHz or 5 GHz Wi-Fi band. This change is also made within the Wi-Fi Settings.
The Robot Controller Console makes it easy to change between the 2.4 GHz an 5GHz bands. It is advised to check the Legal Android and Wi-Fi Band Capabilities table to determine which band to operate in.
Once a Wi-Fi band is chosen there are two options for dealing with Wi-Fi channels. One option is to let the Control Hub auto default on a channel. The other is to set a specific channel. Both options can be accessed via the drop down menu under the Wi-Fi channel section of the Wi-Fi settings.
It is valuable to know how to change the Wi-Fi Band and Channel as technical staff at an event can request to change those settings.
The Wi-Fi band and channel can be changed via the Driver Station Application. For more information on how to make these changes from the Driver Station please see Managing the Wi-Fi Network section.
