@mkck Are you talking about an access point that is not Omada? In that case, the portal will not work.

@SergioQuesada you can't restore until the controllers are on the same version, when you get the update for your OC300 I don't know, I don't think TP-Link knows either But in the meantime, you can...

@SergioQuesada it is only possible to restore to the same version or 5.15.6.xx in your case

@PoKai1992 yes, but you must have two sites, you can only have one router in each site

@ASD_AuZ I think it works really well, one of my kids has an EAP225-Outdoor meshed to an EAP620 HD and it just works. never any problems

@mkck Try and explain yourself a little better, no one understands what your problem is.
