Customers say
Customers like the performance, power levels, and signal of the electronic cable. For example, they mention it works great, reduces downstream power levels perfectly, and is an amazing solution to reduce signal power from cable provider. That said, opinions are mixed on connectivity and upstream signal.

Good product.
This unit does exactly what it’s suppose to. I wanted a pad that wouldn’t cause loss in the upstream bandwidth like a splitter does. Dropped an 8 to 9db signal down to 1 to 2db on the downstream channels of my cable modem while only causing 1db additional power need in the upstream channels.

Check your signal levels – you might need this attenuator (and NOT an amplifier!)
It works well. Cablevision/Altice user. One single “home run” from the cable service to my cable modem (no splitters or other cable runs etc.). One day my Internet kept cutting out. Checking the signal levels on my cable modem showed the downstream signal strength was *extremely* high (+12 to +15 dBmV). My upstream power levels were fine, so I opted for two of these forward path (“downstream”) attenuators, in series, between the cable line and the cable modem.This fixed all issues!I also have a MoCA filter shown in the photo but that’s a “just in case” and “being a good neighbor”, should I ever use MoCA devices.*Bottom line: spend a few minutes researching what your signal levels should be – it may save you from endless frustration and bewilderment!* You may think you need to amplify the signal when you actually need to attenuate the signal strength (an amplifier would have worsened my problem).

perfect signals
using comcast internet and cable tv, tech installed an attenuator and said my signal was too hot, but the attenuator they installed had my snr levels down to 33, which is still considered good but also had distorted channels of espn 2, nfl network and nbcsn. using a netgear cm 1000 modem and xr500 router and extreme 2 way bds102h splitter. after research and good reviews on this attenuator I gave it a try and works perfect. Have 2 of these, one connected to the back of my modem and the other to the back of my cable box. Mostly fixed my download power and distorted channels. Also helped my xbox one x wired download speed from 151 Mbps to 290 Mbps and upload from 22.6 Mbps to 23.8 Mbps. Here is a before and after of this attenuator and what is recommended.download power before: +6.5 dBmV to +8.9 dBmVdownoload power after: -0.1dBmV to +2.0 dBmVrecommended Power Level: -5 dBmV to +5 dBmVdownload snr before: 39 dB to 42 dBdownload snr after: 39 dB to 42 dB recommended Signal to Noise Ratio (SNR): 32 dB to 50 dBupstream power before: 39 dBmV to 40 dBmVupstream power after: 40 dBmV to 42 dBmVrecommended Upstream Power: 32 dBmV to 50 dBmVno distorted channels

6dB Forward Path Attenuator, fixed cable modem timeouts and restarts
Like: fixed cable modem uplink problems, low cost, no wall wart/power supply needed. Dislike: don’t know why it works so well. ** So: before I got this little helper, I was considering to buy a Return Path Amplifier such as $40 Antronix RRA1-10 (used this before for same kind of problem). Problem was: all power level were still in the “should still work” range, for instance 0db downstream channels, 45-50db up, the SNR over 30dB, yet the internet connection became disconnected on daily basis. I had an 6 year old (4×8) cable modem, with 4 channels uplink, and 8 channels downlink. Replaced it with 4×16 capable, brand new modem, but it didn’t help, as T3 timeouts persisted with new modem just as well, and daily modem restarts could be seen from modem logs. Then I installed this FPA and magically: no more T3 or modem restarts, for many days in a row. Now with this FPA installed, been running over 2 weeks in a row with squeaky clean event log. The oddest thing is that nothing dramatic happened on the power levels, as it now stands -2 to -5 dB downlink, 46 to 49 dB uplink depending on what time of the day. SNR on downlink (forward path) is 35dB or better and no uncorrectable errors (FEC) seen on downstream counters. I’m glad I tried this product first. There were even lower cost similar for sale, but I chose this source, based on having a reputation.

It works well
Have a new Docsis 3.1 modem on WoW 200x10M and thought would try this out, though my downstream power is decent. Average is maybe 8.0 dBmV. Upload is marginal, 3 of 4 channels slightely above 50, but under 53.After attaching this, downstream is very nice, just over 0.0 for most, 3 slightly negative. However, for upstream have 51.0, 47.0, 53.0, 51.0, up just a very little bit.I will probably remove this attenuator and set aside maybe for another day.For the upstream, I am not interested in paying $50+ for an Active Return Amplifier if not truly needed.Mine does not have the pretty green.

Great, simple little solution
Over the last few weeks we’ve had intermittent internet. Sometimes our modem would lose the signal for a few seconds, sometimes a few minutes, sometimes a few hours. The info the modem was giving us in the error log just seemed to corroborate what we were experiencing, random intermittent signal drops. A little research on the error logs was getting some results telling me to get a technician out to replace the line from the telephone pole all the way back to my modem; some search results told me to check the incoming signal power levels first. Apparently even when your incoming signal is an acceptable range, some modems can be picker than others. This little attenuator took all of 30 sec to install and it took us from a max of 9.8 dBmV downstream to a max of 3.9 dBmV. This pleased out picky little modem so much we’ve a had rock solid connection since installing, as well as zero (!!!) corrected or uncorrectable packets thus far.
