Wireless clients can ping wired side but cannot ping neighboring wireless clients. They are also unable to get the IP address from the DHCP server on one VLAN
In order to make sure that the wireless clients can communicate among them, configure the bridge-group 1 command on the radio interface.
Note: When the bridge-group 1 command is issued on the radio interface, these commands are automatically issued:
Do not disable these commands. These commands are required for the wireless communication to occur. If these commands are disabled, wireless clients may not be able to communicate with each other.
Also, if the bridge-group command is not configured for the VLAN, the wireless clients are not able to get the IP address from the Dynamic Host Configuration Protocol (DHCP) server on one of the VLANs.
To overcome this situation, you can bridge on any interface, including any serial interface, regardless of encapsulation. Bridging can be configured between interfaces on different cards, although the performance is lower compared with interfaces on the same card. The serial interfaces must be running with High-Level Datalink Control (HLDC), X.25, or Frame Relay encapsulation.
To assign each network interface to a bridge group, issue the bridge-group command in interface configuration mode. To remove the interface from the bridge group, issue the no bridge-group command. The number of the bridge group to which the interface belongs must be in the range of 1 to 255.
Configure Bridging on VLANs
Perform these steps to configure integrated routing and bridging on VLANs, beginning in global configuration mode:
Command or Action
bridge [number | crb | irb |mac-address-table]
Router(config)# bridge irb
Specifies the type of bridging.
The example specifies integrated routing and bridging.
interface name number
Router(config)# interface vlan 1
Enters interface configuration mode.
We want to set up bridging on the VLANs, so the example enters the VLAN interface configuration mode.
Router(config)# bridge-group 1
Assigns a bridge group to the interface.
Sets other bridge parameters for the bridging interface.
interface name number
Router(config)# interface bvi 1
Enters configuration mode for the virtual bridge interface.
ip address address mask
Router(config)# ip address 10.0.1.1
Specifies the address for the virtual bridge interface.
Repeat Step 2 through Step 6 above for each VLAN that requires a wireless interface.

Hello,I'm migrating from AireOS controllers to these new 9800. In order to decrease the number of SSIDs emitted by each AP we were using interface groups in AireOS and it was working as expected; depending on the IP of the client, it's traffic was placed ...
