This is common for the readings to vary at different times of day.  It can reflect goings-on on the power grid, people leaving for and returning from work, street lights, and other things.

So it's best to filter when things are the highest.  Then you will be protected when things are the worst.

We do not use DD-WRT, but our firmware does support CTF (cut-through-forwarding). It must be enabled (default is off) by going to Advanced > Miscellaneous.

However, some other advanced features could interfere with CTF on this router. Features such as QoS could disabled the CTF.

We don't offer a whole lot of support via phone or Internet for advanced features like this, but the router does support this one :)  We will certainly try to help you how we may.

Just make sure your cord is grounded properly at ONE end (we recommend the end that plugs into the computer) where the user is located.  So make sure the other end is isolated - you can use one of our isolators for that if it is plugging into a metal switch or router that is already grounded for example.

Yes, that's correct the cables we sell will both perform the same for EMF.  We cannot recommend or speak to other cables, because there are many designs for cable construction and shielding.  We have seen some very bad designs out there that will not do a good job for EMF/EMR/EMI purposes, even though they are labeled Cat6 or Cat7.  So best to stick with our cables.

Just make sure you properly ground the cable at ONE end.  We recommend grounding at the end near you - where your computer or device is.  Then the other end can plug into a plastic port on a switch or router.  If you have a metal switch/router, then we recommend using the ethernet isolator at the switch/router.  For laptops that have either plastic Ethernet jacks (ungroundable) or NO Ethernet jack at all, the Ultimate grounding USB to Ethernet adapter is the way to go.

Does this answer your question?

Would it be OK if we made your question and our answers public so that it may help other people out?

Run everything off of DC to begin with.  Do not use an inverter.

I would only recommend using an inverter if absolutely necessary, and then I would only run it during that time as little as possible and disconnect it completely when finished.  But these days you can find DC appliances and devices and adapters for everything, so 120 volt AC is really not needed at all.

We don't have any published information on that right now.  But the parallel DNA filters work very differently than the Satic filters.  The readings will be lower on the Satic filters than the PxDNA or RxDNA filters, but the frequencies will be totally different.  We have witnessed capacitor-style filters such as the Satic/Stetzer/Greenwave can show an increase of some frequencies on the line.  This was noted on an NFA1000 meter.  No filter, not even the DNA parallel filters, seem to be perfect.

Some people complain about capacitor filters.  Some people report their lives have been saved/changed by them.

We hope to have some testing results we can publish in the future.

What method/meter/device are you using to measure or detect the EMI.  What is it showing or reading?

A higher number means more unwanted energy (microsurge electrical pollution also called dirty electricity or EMI) is on the line.

My guess is that the battery backup is helping from the standpoint of other power quality issues such as brief sags or drop in power causing your system to glitch.  Does this make sense?  While it's helping with one thing, it is also not providing cleaner power, if that makes sense.  Over time dirty power can also wear out a computer circuits causing premature failure of electronic components.

This is not something we have measured.  Different models may operated/behave differently and at different frequencies.  Do you happen to know the frequencies they use for data transmission?  Most likely the meters are producing microsurge electrical pollution (dirty electricity/emi) as they most likely use a switch mode power supply.  The filters will help with that issue.
