Hi, EAP110 doesn't have an extra spare wired port.

Is your product EAP115-wall?

You may give the port a non-exist VLAN ID to avoid the situation.

With this configuration, clients plugged into that port will have no access to anywhere.

Hi Vincent

Thank you for your reply.

My EAP hasn't got a spare port so I guess your suggestion will not work.

Probably the solution is on the switch port that's connected to the socket/EAP but I´m not sure how.

I have an option on the switch port to select a VLAN but If I choose the Guest Option only probably when I connect the EAP to this port the LoT wifi will be also off.

If I understand correctly,  you want the EAP110 to be the only client that can get Internet access from the switch cable.

You are using SDN switch, right?

You may refer to the following guide to configure 802.1X authentication, and the EAP110 is the client.

Thank you @Vincent-TP 

I can´t very your suggestion because this is too complex and I´m using a Macintosh

  @Vincent-TP this one looks super simple, I will try.

Thank you so much!
