Dear @MekkaKelvin,
I am unable to complete configuration on my cpe510 device, It started when I tried making use of the quick setup, as an Ap router. It brings up a popup screen "failed to get file"
You may refer to the following FAQ to set the CPE as AP Router mode.
How to Configure the Access Point Mode on the Pharos device, https://www.tp-link.com/support/faq/723/
Note: after the quick setup, the port on CPE510(LAN port of PoE injector) will work as a WAN port,
the PC won't be able to get a connection from it, please connect to your Internet for connection instead.
