UPS makes wifi router squeal

post #1 of 11
Thread Starter 
i just got a [ame="http://www.amazon.com/CyberPower-CP1350PFCLCD-1350VA-810W-Compatible/dp/B00429N19M"]cyberpower 1350PFCLCD [/ame] to hook up all my equipment..

i noticed my cisco WRT610N (flashed modded to E3000) started making a constant annoying high frequency "mosquito" noise. so for a second i thought my router pooped the bed, had aha! moment, quickly reverted the only thing that had changed (the power source) and the noise stopped

noisy power = no squeal
clean power = squeal

WAT!?
THE!?
HELL?!

could the noise be a harmonic of the "pure sine wave" the UPS puts out?

Sounds like a good time to throw something across the room. Had a router do this and had to go exchange it.

Is the noise actually coming from the router or from the router's AC adapter? How old is it?

Reason I ask is because I've seen AC adapters start squealing as they get older, probably from aging components (caps?). If it is a good router and is the AC adapter squealing, you can probably buy a cheap universal adapter for a few bucks.

its coming form the router itself, turned over it gets louder as the sounds leaks from the vent holes

/bump 4 my silly inconclusive non-experiments


ok so i bought a new router and it started doing the same awful noise the first day i got it. i used the UPS to power it, so again i blamed the UPS and myself for ruining my new top of the line router by overpowering it (or so i thought)

amazon sent me another one as replacement. for a few hours i pondered what to do with the 2nd new router. should plug it to the UPS to test my stupid theory - if it starts squealing the UPS somehow is delivering to much power permanently damaging some capacitor making it whine/squeal. the UPS display even read "output: 124V", i thought - "those 4 extra volts! aha!" rolleyes.gif

eventually i slapped myself out of it and plugged it straight to the wall outlet never using the UPS... well guess what. same.effin.noise. wth.gif

are my hearing abilities getting better as i get older? isnt it supposed to be the opposite confused.gif lol

i guess just going to have to move the noisy thing to the other side of the wall and run a cable to a gigabit switch near all the devices. wouldnt surprise me if the switch (owned for 2 years now no problems) starts squealing too.

All large computing equipment such as routers, switches, drive arrays, and servers made after about 1996 uses the Power Factor Corrected supply and consequently for this type of equipment the power factor is 1.

1350VA /60 = 810!! HA a manufacturer thats honest can't believe it.

Ok you did open the UPS up and onnect the battery right?
If you don't do that, the interior circuitry can be bumping around all over the place on fluctuating line voltages, and you have no low line or power outage protection.

If you did make sure the battery contacts are in their proper places.
You may have "dirty" power and the UPS is constantly switching over to handle the unconditioned power. But you cant expect much from Cyber Power heh?

Next time get a APC or a better brand. But to me it look like your UPS mate

seems like you are slow, or just lazy and did not read the other 7 post in this thread besides your 2 posts. "
  1. how is the UPS at fault if the 2nd new router (3rd router if you count the old one) was never connected to the UPS at still made noise? anyhow, this UPS is compatible with Active PFC equipment, so im not sure wat are you talking about and how it applies to a consumer router kookoo.gif
  2. my UPS sits on a sturdy table inside my brick&steel-construction home on land away from tectonic plate faults and volcanic activity... explain "interior circuitry bumping all over the place" ?! anyway it doesnt matter, see point 1.
