hex rb750 to hap ac lite

Hi all.. we I am trying to connect my hap ca lite to my hex rb750. I get the internet with the hex but doesnt let the hap connect. I have tried to do a static route but wasnt successful. Any help would be appreciate. Thanks

Plug Ether2 of the hap into the hex.
Turn off DHCP Server on the hap
Delete the default 192.168.88.1 IP (under IP > Addresses)
add a DHCP Client for interface: bridge-local

Now you have 1 LAN. If you plug ether1 of the hap into the hex, you end up with a sub-LAN and certain functions like printer discovery won’t work.

Thanks for the reply.
What I did was put the hap lite into PTP Bridge AP on the quick set menu. At this point i log out of winbox and then i was able to see the 2 routers on the login page as before i was not. With this set up i am able to use the 5g wifi on the hap but thats the only signal, i am not able to use the 2g and guess. Does anyone know if this can be fixed to use all channels?
