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.
