By default, the SBG6782-AC is set up to use WPA wireless security with the Wi-Fi security key (sometimes referred to as the wireless password). Â The Wi-Fi Security key's string of characters would need to be entered into a wireless client (such as a laptop or tablet) in order to have wireless connectivity.
At times, it may be desired to change the wireless key. Â This can be accomplished by logging into the Web Manager of the SBG6782-AC. Â This document describes how to change the Wi-Fi security key.
NOTE: The SBG6782-AC is configured by default with WPA wireless security. Â To support legacy wireless devices using WEP wireless security please refer to article # 8159Â - SBG6782 (v8.4.x): WEP Wireless Setup (Primary Network).
To Change the Wi-Fi Security Key
- Launch a Firefox or Safari browser.  Enter http://192.168.0.1 into the address box, and press the Enter key. Â
NOTE: A browser message on Chrome, Edge, Firefox, and Opera, may appear when accessing the Web Manager. Â The message includes 192.168.01 uses an unsupported protocol and ERR_SSL_VERSION_OR_CIPHER_MISMATCH. Â The Web Manager uses an earlier version of the TLS protocol and does not match the version allowed by the web browser. Â Safari browsers on Apple PC and mobile devices are not impacted. Â The workaround to access the Web Manager with a PC is to use the Firefox browser and set the TLS version to 1. Â For workaround instructions refer to article #Â 19435 - 192.168.0.1 uses an unsupported protocol.
 - A security or private risk alert may appear on the web browser advising users to proceed with caution when accessing the Web Manager.  There is no risk in proceeding to the Web Manager.  For instructions to bypass the alert screen, refer to article # 18181 - Alert Message for Web Manager Access.
 - On the Login page, enter admin or a customized username in the Username field.
 - Enter motorola or a customized password in the Password field.
NOTE 1: On later versions of the SBG6782-AC, the Wi-Fi Security Key is used as the default admin password printed on the bottom white label. For assistance with Web Manager Access, refer to article # 18755 – SBG6782-AC: Web Manager Access.

 - On the Wireless - Primary Network Settings page:
a.  Select the desired frequency tab to modify (2.4 GHz or 5 GHz).
NOTE 1: Choosing the Wireless Interface only determines which frequency settings are desired to be modified. The 2.4 GHz and 5 GHz frequencies are already enabled simultaneously by default.
NOTE 2: The 2.4 GHz frequency supports 802.11 b/g/n wireless clients, while the 5.0 GHz frequency supports 802.11n wireless clients only.  802.11n devices will generally perform better in the 5GHz range.
NOTE 3: In this example, the 2.4 GHz frequency has been selected to modify.
b. Passphrase - Enter the desired WPA key (wireless password) to use. The WPA key must be 8 - 63 characters.
