Question: [![enter image description here](https://i.stack.imgur.com/I8qAm.png)](https://i.stack.imgur.com/I8qAm.png)I want to have a wired Internet connection before or after a PoE access point.

Is that possible?

Answer: 
As far as I understand your problem: on the location of the AP you want another, wired Internet access? You can run the AP's patch cable through a switch to add ports to the network.

However, (usually) PoE doesn't pass the switch, so you'll need to connect the switch to the LAN side of the PoE injector. Then, from the switch, run another cable through the PoE injector and then to the AP as before.
The Access point has the Ethernet port,there you can connect a PC or Switch.from that port you can get access

user will get access on the same AP IP range.
