Objective

This article is all about Bridge Group Names (BGNs) on a Cisco Business Wireless (CBW) mesh network. Topics include the purpose of BGNs, how they are created, how a mismatch can cause issues with connectivity, and how to view/edit them.

Introduction

BGNs are created to optimize connectivity between APs that are supposed to work together, even when the APs are in close proximity to another wireless network.

If you set up your network with all APs at factory default

When you conducted the Day Zero configurations for your mesh network, a BGN was automatically created. It is the same as the first Service Set Identifier (SSID) you entered, up to the first 10 characters. This BGN is used within APs to associate and make sure the APs are staying connected properly. If you set up your Primary AP and then join subordinate APs, the BGN should automatically match with no further configurations needed.

If you reset a Primary AP or moved a configured AP to a new network

If you perform a reset to factory default on the Primary AP, or move APs from one configured network to another, this can cause a mismatch of BGNs.

When an AP tries to join a network in a scenario where the BGN doesn’t match any networks available, the subordinate AP will attempt to temporarily join the network with the strongest signal. The AP will be able to join the network if it is Allow Listed and approved.

Once the AP has joined the network, since the BGN doesn’t match, the subordinate AP will continue to look for a matching BGN every 10 to 15 minutes. This will cause the connection to drop and then join again if a matching BGN isn’t found. This can cause a lot of problems with connectivity in the wireless network, especially when there might be a stronger wireless signal coming from another wireless network.

As a simple solution, for all APs to work together, you should make sure the BGN on all APs match exactly. To clear out the BGN on the other APs, you can do a Reset to Factory Default on them, or you can manually change each one to match.

Beginner Help

This toggled section highlights tips for beginners.

Logging In

Log into the Web User Interface (UI) of the Primary AP. To do this, open a web browser and enter https://ciscobusiness.cisco.com You may receive a warning before proceeding. Enter your credentials.You can also access the Primary AP by entering https://[ipaddress] (of the Primary AP) into a web browser.

Tool Tips

If you have questions about a field in the user interface, check for a tool tip that looks like the following:

Frequently Asked Questions

It is recommended that BGNs get assigned to the mesh extenders with the most hops be configured first, working up to the least number of hops. After that, the Primary Capable APs bridge group names should be assigned. The Primary AP BGN should be configured last. You can view and change them one at a time by performing the following steps.

Step 1

Log into the AP and enter your credentials.

Step 2

Switch to Expert View by clicking on the arrow icon.

Step 3

Navigate to Wireless Settings > Access Points. Click on the edit icon of the AP you want to edit or view.

Step 4

A pop-up will ask for confirmation that you want to edit the AP configuration. Select Yes.

Step 5

Click the Mesh tab. Here you can view and change the Bridge Group Name. If you make changes, be sure you click Apply.

Step 6

Repeat the steps for each AP in the network you want to check. Click the save icon to permanently save any changes. Keep in mind that when a bridge group name is assigned, the device performs a reboot. Since a reboot interrupts Wi-Fi, it is not recommended during business hours.

Conclusion

Congratulations, you now have a decent handle on Bridge Group Names. This knowledge can be used as another tool in your toolbox, helping to keep your wireless network connected. If you need more guidance, check out more articles below.
