Hello, 

I have 6 ''Deco E4 AC1200'' at home and have a problem with CCTV and Intercom system (All is Hikvision devices).

I'm unable to find devices on network that are connected to Deco via WiFi or via LAN cable. I think some ports are blocked by firewall or something similar. Hikvision by default use TCP port 8000. 

Tried with other option: Used TP-Link TL-WR840N as Range Extender and it works normally.

Please if anyone have any solution, please write down and i will test it.

Thanks in advance.
