Hello - need some advice.

I have four DECO BE10000 units. I will name them Main, #2, #3 and #4:

• Main is connected to an internet modem.
• Main is connection via ethernet to #2, #3 and #4,

Most of the time, everything is great.

But periodically, when I look at the DECO Android App, it reports that #2 of the remote BE10000 is unreachable. Then a few minutes later, it will report that #3 BE1000 is unreachable, as soon as #2 is back one line. Then a few minutes later, #3 will return back online, but #2 is again unreachable at the exact same time. A few minutes later the cycle seems to repeat. I am not sure how long this repeats. It eventually seems to clear somehow.

This cycle is not always between #2 and #3, but may involve #2 and #4, or #3 and #4. It never seems to involve Main.

Today I looked at the light on on the #2 and #3 as this occured and I do not see it breifly flashing like it was reset or power pulled and was rebooting.

It will continue this cycle for some time.

Today I powered off #2 and #3, the problem stopped, and everything returned to stable. No further repeat of this cycle in a few hours.

It does not do this all the time. Most of the time everything is stable.All devices up and stable.

Any ideas what might cause this cycling?

Thanks in advance.
