Back-UPS causing WAN and Wifi to go down

[Anonymous user]

Hi,

I have had a BE550-UK since March 2015. Since then it has been connected to the same equipment: a router, a server, a printer, a NAS and a Sonos bridge. 

It has worked very well since then until last week. 

My router started dropping WAN and wifi regularly. Sometimes as often as every ~15 minutes. 

I started turning off all my equipments one by one. I even replaced the router (with the same). Same problem was occurring. 

I then disconnected all my appliances from the Back-UPS. The problem disappeared. 

So it seems my router, including the new one I purchased to troubleshoot the problem, is losing power from time to time from time from the Back-UPS, causing it to reboot. 

Any idea?

Thanks

Found the problem.

I had activated the energy saving option.
