Hi,

I would like to add LTE failover capability on fore mentioned mikrotik device.
Does anyone have a device list compatible with this model?

You need set your LTE device on passthrough mode to get your ISP address on your hAP AC2. Simply make sure that the route distance is bigger than 1. I assume that this can be configured on LTE device also. Simply make sure that LTE device it's a MikroTik device.

Regards.

Hi,

Nah man, I need a compatibility device list (USB dongles) that can detect and work on the HAP AC2.

***EDIT*** Oh and I need it to have a micro SD slot also.

Good luck. I suggest to you contact directly with MikroTik support for that.

Regards.
