Hello, I do not know if this will be the correct section, they tell me anything and I go to the corresponding section. You see, I have internet through a WISP, in my home I have an antenna that has a Nano Loco M5. 2 days ago I bought a UPS, this is: https://www.linio.com.ar/p/ups-asium-r1000-1000va-600w--x0crym. The voltage output ranges between 195VAC-255VAC, I have connected a 650W pc with 2 monitors, a router and the POE, whose input range is 190V-240V. As I mentioned earlier the UPS output varies, it is never in 220V, it is usually in 208, 210, 240, 245 etc. The problem with the antenna is that the configuration is reset and it just happens that this problem started when I connected the POE to the UPS. The technician told me that it is a voltage problem and that when the antenna detects a voltage peak it restarts. So to have more than one version of this problem I turn to you. Maybe I should connect the POE to a stabilizer and the stabilizer to the UPS since I suppose that the stabilizer will be able to maintain the output voltage range with less variation at the same time that in case of power failure it will continue to work. Specifically I have these doubts: 1) Is it true that the M5 resets the configuration while connected to the UPS? 2) Isn't the UPS supposed to maintain the voltage output at 220V? Regards!
