N500 and N550

Is anyone having issues getting a cnReach N500 AP to talk to a N550 EP in 450 band?

What firmware should each one have?

We have a N500 AP with two N500 EP’s in place for couple years. One of the EP’s quit. We replaced it with a N550 and we cannot get the AP to talk to the new N550 EP.

N500 should work with N550. Just make sure to connect N550 to internet to upgrade to latest version. N500 and N550 are compatible. Please open a support ticket if you need additional support
