Hi  @Dkawayevu 

Thanks for posting here.

Will the main EAP bridge be wired to the EAP772, or will you plan to use wireless connectivity?

It will work if you plug the EAP main unit into the EAP772 with an Ethernet cable.

Internet---EAP772---wired--EAP bridge_main ))) wireless ((( EAP bridge_sub      √

Internet---EAP772))) wireless (((EAP bridge_main ))) wireless ((( EAP bridge_sub     ×

But EAP772 only has one Ethernet cable. So this is not possible with the current installation.

Do you have another EAP unit? If so, you can build a mesh EAP772 with other EAP units, which will save the Ethernet port for the EAP bridge.

The topology would be:

Internet---EAP772_1))) wireless ((( EAP772_2---wired--EAP bridge_main ))) wireless ((( EAP bridge_sub 

Feel free to let me know if anywhere unclear, or you have any other questions.
