Using an UPS on a surge suppressor is also a HUGE no no. Also if this home wiring has no ground why use surge suppressor strips? they will do NOTHING to protect your equipment on non grounded wiring. are you using powerline ethernet? if so you should not use non powerline Ethernet surge suppressors on the same circuit. the link shows the type of suppressor/powerline im talking about. »tiinetworktechnologies.com/repos···0108.pdf Also many surge suppressor manf. dont recommend using more then 1 total suppressor on 1 circuit. DONT plug/unplug HDMI with devices plugged/powered in/on,,,i know people who have started house fires doing this and or destroy equipment "serious on this" have you checked all plugs for reverse polarity? if not please do so on all plugs »www.homedepot.com/p/Gardner-Bend···Y9pOG2So not saying this is your issue however.....

I'm trying to understand why this is happening, and its getting to the point where we will have to rewire these stupid outlets to a grounded and to a different circuit entirely! Even if you did this and dont find the cause you will still end in same result with voltage on a new grounded line on a new circuit. i had an issue like this and could not find cause, had outside breaker box replaced and grounding rod installed, house does have proper grounding now all this and still had power returning on cable line.... the end result a linux router/pc was at fault. it was one of the power supply fan connectors touching the pc chassis

alexintexas join:2003-01-11 San Antonio, TX Reviews: ·RoadRunner Cable ·Clearwire Wireless	reply to scififan68 also have you exchanged the modem? new modems do go bad one way to test, touch the cable connector on the modem, warmer the you? warmer then room temp? more then likely a bad modem. 3 total arris modems have done this all 3 new out the box, current arris connector is room temp to touch,,last one was very very warm to touch = not good...

scififan68 join:2010-10-02 Fremont, NE Reviews: ·Time Warner Cable	We have no ups in this house and I have no idea why they choose a surge protector and its not like any of the devices have a ground pin anyways and only the tv has a ground pin and I've also noticed that cable boxes and modems aren't grounded either. No Powerline networking, only C2G Cat6 Ethernet cables and wireless N via the gateway device. I've checked the outlets with my tester and it says open ground which is to be expected for 1948 romex like power wire. Now I was thinking of putting the dvr box and tv on a new wire back to the circuit box and if one of the devices We have a dlink media streaming box, a dvd recorder/player and an audio receiver that is plugged into that power strip when we have sporadic issues. Could one of those devices be causing this issue or is it something else? Yes we swapped the TG862G for another and swapping did nothing, it still rebooted, but now its not rebooting, but the stray voltage causes the uncorrectable errors to jump up and errors to happen on the modem and these issues happened with my Zoom 5341J and Sb6141 as well, so the modems being bad is unlikely. It seems that different chipsets handle this differently, but all show high amounts of uncorrectable errors. Now the coaxial port is a bit warm, but this gateway/modem has been on for 9 days now and the small amount of heat is from the inside chips. We have a fairly large network of computers and the router part is holding up very well, and all errors are with the cable modem part.

This port should not be no more then room temp if its warm to touch its more then likely a bad modem,,now if power returning on the cable line is the cause of this warming i could not say. also my point on surge suppressor use in non grounded homes. my point is that there is no need to get a false sense of security "all it equals is an expensive power strip" because a surge suppressor is useless in non grounded homes = wasted money where a power strip is much cheaper. now i know you stated you have checked the drop itself and no voltage correct? if you are sure there is no power coming from the drop then its something in your home that is shorted. i do wish you luck on isolating this. in my case my linux router pc was in this condition over 2 years only reason i found issue was the pc started doing grinding noises, i took side cover off "pc powered on" in doing so i got a huge array of sparks which led me to the shorted fan connector to chassis, the grinding noise was a failing hdd one more question. do your lights dim on one side and get bright on the other? if so is it more pronounced in windy conditions? if you dont have this problem ignore the question. if you do call your utility co ASAP to fix this added could you please post your complete event log from your modem and status page, you could be having signal issues

alexintexas join:2003-01-11 San Antonio, TX Reviews: ·RoadRunner Cable ·Clearwire Wireless	reply to scififan68 also try posting in the direct forum ask them if they can setup a line monitor. you also state removing a power strip and there is no voltage, but putting the same power strip on a different plug in the home when you moved it what was then connected to that strip? seems you maybe close to isolating the fault and yea i know its frustrating, you then say removing the power strip completely then using the new surge protector voltage comes back? if this is the case unplug everything undo all hdmi leave hdmi unplugged, start plugging things one by one checking voltage after each what are the results? in my case again i was as stumped as you,,at the time all appliances in the home where brand new, stove, washer, dryer, fridge etc, all tv's new flat screens, i was stumped. so i unplugged everything in the home except for the faulty pc router, home pc's, network gear. tested all plugs in home found one with ground fault and another with reverse polarity, fixed both those, but cable still had power on it...it never dawned on me it could be the faulty pc router = stumped and frustrated

scififan68 join:2010-10-02 Fremont, NE Reviews: ·Time Warner Cable	reply to alexintexas There was no doubt voltage coming from the dvr boxes coax, but there seems to be noise on the line still, random periods where the SNR drops to 34-35dB(normally 36-37dB), and signal drops from 3-4dBmV to -2.5dBmV to -1dBmV, but I have no idea why it does that. But it eventually stops and the signal stays at normal levels(2-4dBmV) for most of the time and it seems to be coming from under 723MHz, which is in the 700MHz cellphone block. Downstream 1 4 741.00 MHz 2.01 dBmV 36.84 dB 256QAM 7517740075 24844 138011 Downstream 2 1 723.00 MHz -2.43 dBmV 34.21 dB 256QAM 7168202330 21178 99715 Downstream 3 2 729.00 MHz -0.31 dBmV 35.08 dB 256QAM 8481790404 25048 106910 Downstream 4 3 735.00 MHz 0.89 dBmV 36.17 dB 256QAM 7408372641 25506 134860 (Most of the codeword errors came from the backfeed I believe, so they aren't relative) I'm wondering if the snr dropping is caused by something like cellphone band interference? There is some codeword errors still, but most has gone away. I have checked the coaxial cables and found no voltage on any of them. No dimming of the lights as far as I can see, and the power works well except for the backfeed. I thought it happened more during windy weather and during heavy snow, but that was before I knew of the backfeed.

alexintexas join:2003-01-11 San Antonio, TX Reviews: ·RoadRunner Cable ·Clearwire Wireless	even tho you dont show upstream stats your wide download signal variances do indicate noise on your line ie: -2.43 dBmV 34.21 dB 2.01 dBmV 36.84 dB contact direct support and ask if they can setup a line monitor. are these numbers from no voltage on the line or voltage?

I've been in contact with DPC, which is above Tier 3 support level and they see some variation but nothing out of the norm. But as you can see something is leaking into the system and its not the backfeed voltage, since I already checked for that and found nothing. Doesn't seem to kill my internet or cause any issues, so I probably shouldn't worry too much. It's just something I've noticed that happens even with the power strip unplugged.
