Not sure what you mean. Of course, if you disconnect the CPE510 from your LAN or turn off the power you can't connect to the CPE anymore. If you indeed mean that after powering on the CPE again or connecting it to the LAN again you can't connect, then either you did forgot to save the settings permanently or you use DHCP and the CPE probably got a different IP from your DHCP server.

Hi thanks for replied, Sorry for my broken english. I can reach the IP and setup GUI, but when i unplug the cable or restarting the power, All the settings are gone, need to press the restart button first, than i can reach the default configuration. Hope you understand what i mean

every time i unplug the lan cable or turn off the power POE, CPE510 can not connect (no valid IP). it can re-connect when I press the reset button and configure from first time

Now I Wonder Why you need to unplug the LAN cable or turn off the power. To reboot it manually?

because it is installed in our store, when the store closes, we turn off all the electricity. The problem we faced when we turned the power on again, all configuration reset and we can not connect to CPE to configure ( no valid IP). And we need to reconfigure again with press the reset button. Dunno why this happen

Yes, I can understand, but I cannot reproduce this behavior.

Make sure you " Save Changes" after " Applying" any settings. Set a static IP for the CPE, then " Apply", then " Save Changes".

Next, reboot. If the CPE loses its settings even after changes have been saved, your device may be faulty.

I'm sure i already save all the configuration. If the device fault, why it can connect when i press the reset button and reconfigure ? Theres no hard reset on CPE / cmos rest ? or something else :(

I understand it better now.
But would you mind telling us the settings configured on the CPE510? Is it a P2P link or P2MP link？Your network layout really matters. Also the quantity of CPE. Does the issue happen on only one CPE510 or all CPEs？ A static IP for CPE and what is it? You mentioned you have a store. I just think about that your main house also installs a CPE510.

All configuration reset is really abnormal as long as it reboots. How did you judge it? Did the link between two CPE510 disconnect? Or you can not go to Internet with CPE510?
