Hi all,
I'm continuing my experiments with my bad reactions to large file downloads via high speed internet (DSL). I had hopes that replacing my unshielded phone cable (to the modem) and unshielded ethernet cables with shielded versions would make a difference, but I've replaced them both with double-shielded cables, and my reaction is the same. I guess this shouldn't be surprising to me, because shielding rarely helps me. About the only time I've noticed a difference with shielding was my use of a triple-shielded VGA cable, but even then it could be the double ferrite cores on the cable that made the difference. So next I will experiment with EMF protection devices placed on the cables, router, modem, etc. I have already proven to myself that the Quantum Home placed in the room helps, but I haven't done much experimentation with devices placed directly on the modem, router, cables, etc. And I've already experimented with using different ethernet interfaces on the computer, by using 2 different computers and also using an ethernet to USB adapter. All of those are bad. I'll figure this out... Marc |

Has anyone had any improvement in symptoms using snap-on ferrite cores? I could certainly add all sorts of ferrite cores around my desk -- on power cords, ethernet cables, monitor cable, mouse/keyboard cables, USB cables, etc. Of course, there seems to be a wide variety of ferrite cores on the market, and I'm not sure what exactly I should be looking for when buying one. Or whether it is worth pursuing at all... Marc |

Seems like a good idea. Some are geared for higher or lower frequencies.
But if you're at the computer the main problems could easily be the components themselves and not the cables. The AM radio test might shed light on that...

Could be the hard drive activity? I'm pretty optimistic that
solid state drives will be better. See if you can save directly to a memory stick? I do like the OLPC which is disc free but unfortunately seems a little slow and the screen is quite small...

I know a fellow who has a bad reaction whenever
video is streamed. His computer is over 50 ft away using fiber optic video and USB. So it seems that the problem may be the DSL land line and not the computer itself.

Hi, Marc,
I have that problem too (I have DSL). I don't react except when downloading or uploading large files or streaming video. So, I avoid doing this,and when I have to down or upload something, I just leave the room. I have thought it is from my hard drive, but maybe I am wrong??? Did you have this problem before you went to DSL? You just switched recently, right? Good luck with your experiments!

I did however get a new computer, and I think the new computer is worse than the older one when it comes to Internet activity. So certainly the computer is part of the problem. I've briefly tried high-speed cable Internet just recently. but have gotten fried every time I try it, so I guess cable is worse than DSL for me. But I'm continuing to experiment with various types of cables and wire positions, so I haven't concluded anything yet... other than the Quantum Home definitely helps this problem. That may end up to be my solution, but I'm going to experiment some more... Marc |

Thanks, Marc,
For the info. I got some info from my new doctor on some possible remediations but I cannot write about it this go round--been online too long. lol Will try in 3 days to send the info. When my last computer went belly up, I did not react at all to it. The newer one fried me. The newer ones have twice or more the hard drive power of the older ones plus allthe infernal wifi and broadband cards,..... I tried to get a dumbed down computer but they don't make them anymore! Will share soon--don't know whether it will work better than the Quantum Home tho, Diane --- On Tue, 1/27/09, Marc Martin <[hidden email]> wrote: From: Marc Martin <[hidden email]> Subject: Re: [eSens] DSL To: [hidden email] Date: Tuesday, January 27, 2009, 5:14 PM > I have thought it is from my hard drive, but maybe I am wrong??? > Did you have this problem before you went to DSL?

When my last computer puk replies - perhaps you should consider the concerto effect of the elctronics as a whole in the new pc these hit the right notes or in your case the wrong ones. You might also consider the neuro adaption that may take place as your body may take a while to decide wether the new equipment is good or bad but given the density of electronic components in a laptop the chances are that you will get a bad reaction as they simply throw out all manner of RF.

Marc, did you ever figure this out? I shielded my DSL modem before thinking about the wires because it has built-in wireless and seemed to be a problem even with that turned off. I still had trouble, and had to shield both the wires and the modem before I got a perceptible improvement. Since you mentioned downloads being a problem and one computer being worse, it might make sense to try saving files to a flash drive. (You probably already know this, but just in case,) hard drives don't always store files contiguously, especially big ones. If they have to break a file up, the read-write head often moves in and out on the disc's diameter, and there's a powerful neodymium motor that drives it. That could be your problem. |

When was this written? :-)
My computer and internet are fine these days... I'm using a desktop tower and using cable internet. All wired, of course. And yes, I've got an SSD as my main drive, and a regular hard drive for additional storage. But yes, I was having problems with only wired components -- my modems didn't even have wi-fi to turn off. I think most of my problems with the cable internet was due to a ground loop, which I fixed with a cable isolator.

Oh, I see, that was written 7 years ago!
I've since updated to a new computer, and dumped the DSL for cable. I've also updated from an LCD monitor to an LED monitor, and change computer speakers. So everything has changed... :-) Marc |

Yeah, I know :) I did a search because I didn't want to start a duplicate thread, and I saw that there was no resolution to this one. I'm not sure if WiFi was really the problem on mine. I think the DSL signal is probably in the high kHz or low MHz range, and there have to be conductors inside carrying it as well as something to produce it. |

Says here that DSL can go up to 2 Mhz:

One other thing to consider with DSL is that the filters won't have been designed with ES in mind, so they might allow too much noise through. It should help to install the modem where the phone line enters the house and use one filter to reduce the noise before it goes any farther. It might also help to build/buy a better filter. Searching on Google for "low pass filter" will turn up some technical articles, but it looks like you can also buy filters:
http://www.ebay.com/itm/like/262600679483?lpid=82&chn=ps&ul_noapp=true http://www.ebay.com/itm/like/400483561306?lpid=82&chn=ps&ul_noapp=true http://www.ebay.com/itm/like/111991394002?lpid=82&chn=ps&ul_noapp=true I'm not sure whether any of those would perform better than a stock DSL filter (or even work at all), but it might be worth looking into. |
