Hi

I currently have a hap aclite which I am using as an access point
my internet feed is coming from a 4g Mikrotik SXT (this is new)

at the moment the access point is only giving out the ip address 192.168.88.254
even though the sxt is set to 192.168.1.1

I am looking to see how I can force the access point to use the correct address range
192.168.1.x

any help would be greatly appreciated.

Thanks

Post the config of both machines (my automatic signature below tells you how to anonymize them). It seems that the AP acts as a router with a DHCP server, so it gets its WAN IP from the SXT and keeps assigning addresses from 192.168.88.0/24 to clients on its LAN. Which may be what you actually want or not, so also describe what is the intended result.
