I have a different take on how to configure your hardware from the posts above. I try to set up the system for the easiest operation by cruisers that move from place to place. This entails a double nat at minimum but a double nat is not a problem for most cruiser.
The configuration attached to this post is a default configuration from a Groove 52ac that has a level 3 license and is by default a CPE. You have a GrooveGA 52ac which is has a level 4 license and is by default an AP making the configuration more difficult for you.
The configuration has been modified from the original default by changing the IP's being used from 192.168.88.0/24 to 192.168.89.0/24 so that the Groove will work with your hAP default configuration. It also has the default wireless settings changed to the 2.4Ghz band rather than 5Ghz.
1. Using winbox drag and drop "config-89.rsc" into the flash folder in Files
2. Go to System->reset and check mark No Default Configuration and Do Not Backukp. Set Run After Reset to "flash/config-89.rsc" and then click "Reset Configuration".
Your Groove will be configured as a CPE with the LAN as a DHCP server. It will operate as a stand-alone when connected to a computer LAN port or with a router if plugged into the WAN port.
Start with your hAP ac set to its default configuration. If you use the POE that came with your Groove you can plug the Groove into Port 1 on the router and start using it.
To set your hAP so that port 5 can be used as a WAN port and provide POE-out to your Groove I like to remove port 5 from the bridge and create a new bridge called bridge-wan that contains both port 1 and port5. It is an easy modification to the hAP and works. You lose 1 port which isn't normally important to a cruiser.
To make port 5 a WAN port:
1. Go to Interfaces->Interface List and delete WAN
2. Go to Bridge and create a bridge called bridge-wan.
3. Go to Bridge->Ports and delete ether5 from bridge then add ether1 and ether5 to bridge-wan.
4. Go to Interfaces->Interface List and add WAN=bridge-wan
5. Go to IP->DHCP Client and change the ether1 entry to bridge-wan
6. Go to System->Reboot and re-boot the router.
In your browser or winbox you will enter 192.168.89.1 to get to the Groove. On the Quick Set page you can quickly choose an AP and connect. Check that you get an IP in the Wireless section in the upper right quarter of the Quick Set page this shows you are connected and communicating with the AP.
This is just a minimal setup. You should set the Frequency Mode to "Regulatory Domain", the country to the appropriate setting and the antenna gain to an appropriate setting based on how strong the received signal is. Don't leave the Antenna Gain at 0.
You should add a login password to the Groove and the router. The Groove can be set up to scan both 2 & 5 ghz signals by using the Channels tab in wireless.
