@AxKa You can see the difference here https://www.tp-link.com/en/compare/?type=smb&typeId=5795&productIds=73647%2C59293

@dahls log into the controller locally not via the cloud

@VentoVinte Make sure you have 1gb to the access point. Link speed is probably 100mbps

@dahls you probably have to wait until the people who work at tp-link wake up. They will probably be at work in 6-7 hours. I have no idea what the problem is, if there are not very many access points...

@dahls yes, unfortunately not all updates go without problems, I have had problems many times. what about the router and switcher, is it the same problem with them or is it just the access points?

@dahls then I don't know, it sounds like you have trouble. is all local or are there some romote sites that are the problem.?
