@safefly 

Thank you for posting on the TP-Link Community.

The maximum whitelist rules is 16. If you want to block some unknown devices to connect to the network, you can add them to the blacklist.

While we will also pay attentions to this kind of request, and will feedback to the related department, they will evaluate if this can be improved in the future.

Implementing the access control on my new Archer C80 wifi router (I couldn't find it in the models list), I realize the whitelist is apparently limited to 16 entries, which effectively renders the access control unusable: obviously not enough clients !

Plus, if you think about using the feature, the whitelist edition capabilities are very limited, its import/export capabilities are not provided

Any workaround would be appreciated...

Left a message to customer support - will advise

@safefly it's incredible, I just configured my archer c80 today, and be happy because my old tp-link accepted 30 or more clients in White list to control de.access, and obviously, this is a modern model more expensive, for.sure, I could do it, but when I set 16 client a message: the table is full, its unbelievable, I feel.cheated. My next router, probably won't be a tp-link one. 

@Montoj Hi !

You're right this limited number of entries suck.

It clearly degrades the quality of the unit...
