Power conditioner, avr or ups?

Just another thought: dsl comes in on pretty thin wiring and requires twisted pair to reduce interference - a bad pair might be the issue. Your ISP has diagnostics and might b able to do line test for you. Otherwise, they might just try another twisted pair (you have been a customer for 10 years and you want their help). Good luck.

Hmm techs come out all the time to service the line, but less lately because it hasn't rained much in ages. In most of the time I've lived here and had this isp, whenever it rains hard, I lose my connection completely for awhile. I call a tech and they come out and do whatever they do and all is well until the next hard rain. I think I've heard a tech mention twisted pairs, but I haven't educated myself on any of that stuff tbh. The older I get, the more I actually prefer stuff to be plug and play. I suppose it is fair to say the issue has always been somewhat intermittent. In the last couple days it's been almost non existent, ironically. In general though it comes and goes and being related to power, the phone line and dsl seems likely. Getting a ups is something I wanted to do for ages anyway, but my main hangup has always been fire risk because my place is somewhat warm and can be humid and not the greatest ventilation so a big battery kinda makes me nervous. Also possible odors, the unit itself having an audible hum or some other electrical noise, etc. That consideration is all compounded by the fact that my power almost never goes all the way out and in fact my system is on 24/7 365. Never had an outtage destroy anything and at least use decent very high joule surge strips for any major events that could happen. That's why I started this thread out asking about conditioners. I wanted thorough line cleanup or whatever else can be done without a battery backup.

"whenever it rains hard, I lose my connection completely" - sounds like the cause. Consider corrosion if connection goes out when wet. Can result in power fluctuations in signal from ISP. "The nominal battery (system) voltage is 52.1 V, based on a 24-cell lead-acid battery. The voltage at a subscriber's network interface is typically 48 V between the ring and tip wires, with tip near ground and ring at -48 V. "

So modem gets all this fine voltage - and rain and corrosion mess it up.

I had similar situation but on cable. Took 10-12 phone calls on wet days to get a 'senior field engineer' to properly test. When he 'certified' the problem, it still took 3 visits to fix. Turned out to be squirrels breaking into the wiring cabinet on the pole. They had to replace the cabinet, the connection board and some of the wire. Squirrels are nuts.

Line conditioning is probably sufficient. I tried UPS but got tired of the battery replacement cycle - so you might find one you like .. or not.

Well, I didn't read the whole tread, so if this is a dupe suggestion, forgive me.

It sounds like you've tried everything but a TVRI filter on the line.

I don't know if TV radio interference filtration is built into UPS devices, but it is a lost cost avenue for experimentation.

Here's my search results google page on the topic:


Now that's an impressive link... :rolleyes:

Plug all pc related stuff into it? Or just pc, display and modem?
I found the printer to overload the device and as they are relatively cheap, I don't plug into a backup-power-protected slot. I do add all network equip so as to sustain a full power outage.
Also what about odor, I hear the battery can have an odor and my pc area isn't all that well ventilated.
my CP800avr is right in the corner of my desk and never had an issue.

Thanks for all the replies guys! Will be buying a unit in the next few days and after using it for a week or so I'll update. Looking to spend 200 or so and want sinewave model from either CyberPower or APC.

The most frustrating thing about this issue all these years is how random. Please understand that I am not tormented day and night by this and it's quite sporadic. Last couple days I've watched a few movies and done lots of gaming and no issues. On average if I had to summarize, I'd say 80+% of the time I can hear audio free from these interference, but when it does happen it's just very jarring. I would venture that there are a lot of people who would live with it and not try as hard as I have to address and fix it. Mainly because my pc is so stable otherwise.

Certainly interesting choice.

  1. this is much more expensive than the CB800AVR or APC units (about 1/2 of this choice)
  2. also does NOT contain a battery, so it will not help in cases of power outages

As my 800AVR is right on the desktop, I can hear it engage and disengage. Many times it's just for a minute or less.

I do believe this choice would be better technology, but only serve to cleanup the AC wave shape and clear line noise.

As I mentioned before, the power almost never goes out. In 10 years less than 10 times and any time it went out, nothing was ever damaged, hence I'd ideally like a solution free of a battery, but the jury is out. I will probably try the unit I linked first and if it doesn't help I'll get the cyberpower puresine 810w model.

Sorry I left this thread hanging guys. I appreciate all the replies and feedback as I did learn some things and get some input and validation for some of my thoughts. The truth is I am a lazy procrastinator who is relatively poor so never quick to spend money. Because the issue is intermittent, it hasn't like ruined my life or anything and if I'm being honest, I'm on my pc all day every day and the issue does really come and go and can be very sporadic. Long story short, if I do nothing, my life, computing and gaming will go on mostly fine and mostly livable. Last night I ordered a simple Furman power strip with some very basic noise filtration as a first very cheap and easy step to put my toe in the water. Even if it doesn't help, I wanted to replace my tripplite iso 6 because it has no spaced outlets for bricks. Will update.
