Unfortunately, I had a reset two days ago on the repeater that have only power pairs attached to it. Meaning, it has no relationship with the POE Adapter.I was logging every power surge during this time and what triggered the reset was a simple power disconnected. Not sure if any peak happened, but from 5 CPEs on the same grid, only one lost the connection.No lucky :-(

Yesterday I went to my parents and wired the grounding for the equipment that was losing settings.
As i was wiring it, with the equipment still on, I noticed it would quickly charge up with static. If I touched the grounding terminal every 20 or so seconds, it would discharge at me at a very noticeable degree...

i will keep you guys posted, but I feel that indeed all I had to do was RTFM and act as trained personnel when installing something designed to be installed by a trained personnel

Well, here I am again...

The problem seems to be gone! Over 1 month without a reset.
I acted on it as much as I could.

In summary, the actions were:
-Grounding of the power supply
-Grounding of the CPE210
-Changed the ethernet cable to a shielded one
-Installing an access point between CPE210 LAN Port and the Mikrotik Routerboard CPE (WISP equipment).

As theses changes were very time consuming, i could not do them as scientifically as needed to point what has actually solved it...

Hi there , can you share the topography of your installation , Im trying to install 4 cameras , and I dont know if i should use a base station JWBS510 or just cpe210 , another question how you connect 2 cameras to 1 CPE210 . Sorry if the question is silly im new in this busienss . thanks

It's lucky that I find this post. I have same issue with you. Thank you all for answering nicely. Have a good day!

Hello all, I have the same problem with all of my 4 cpe210 which i am using. Settings stays for 2-3 days, sometimes 7-10 days. and suddenly goes to default setting.

192.168.1.46 is what i use the IP in one of the four cpe.

It looks like you do not have the latest firmware.

 

One of the improvements of 20190928 version is:

 

Modifications and Bug Fixes:
1. Fixed the problem that the device may be reset to factory defaults due to unstable power.

 

Go to your country's tplink support page, then you you might find it.

 

I have been installing TP Link gear for years including CPE210 and never grouded any of it, ever! I can understand if its attached to a metal shed or something but the init is plastic and its bracket is plastic. I think its a load of nonsense. I have over 100 of these TP Link devides out in the wild and non of them are grounded either, not a single unit has packed up or given any issues even in severe lightning storms. The onle time I had a device reset its self was when a joiner put a nail through my cable one time. 

 

Try upgrade the firmware on your devides should be ok also save the settings then reboot the unit by pulling the PoE out and then login again, if you see it say save settings at the top again then I would just replace the unit. It should save the first time. As for grounding, its a load of bull crap.
