The most RARE bizarre network speed issue I've seen!

I am hoping by the slightest-ever chance, someone else has stumbled upon a *phenomenon* and remembers what ever fixed it.

I have never seen this happen before in my over 8 years of moderate-to-high computer/network experience. Please read fully before you try to assume what I am asking or what my issue is - And please ask any questions if you need clarification on anything.

Five computers on wired/wireless network: Three desktops via wire and two notebooks wirelessly. This network has been in place for about four months now, but the "phenomenon" I am about to mention just started occuring last weekend. My ISP is Comcast, my modem is Motorola and my router is a Linksys. I think (off memory) it is a WRT54G Wireless-G (Will edit post to add model numbers to modem and router when I get home.)

Okay here goes! Two of the desktops and both notebooks are great/perfect/no issues etc! Great, no worries. Okay, now the OTHER desktop (less than six months old, great condition): Sometimes with no known ryhme or reason, all the sudden the bandwidth takes a dump! Here I am happy-go-lucky getting great 800K downstream/50ish ping playing games online/etc then *suddenly* my ping (only on this machine, not the others) goes into the thousands, and I cannot download any faster than 10ish/k per second! Must be another PC on the network doing something, right? Nope! Completely physically disconnected them from the router and disabled wireless. No help. Some weird background/software process on this desktop? Nope! Did a full/clean reinstall, and randomly it starts to do it (the speed problem) again. Perhaps a temporary "burp" from the modem/ISP? Nope! I test download something on another machine meanwhile and it gets the 800k and great pings still.

You know what DOES fix it, at least for a while? Swapping the ethernet cable to the PCI NIC! Problem solved right? THOUGHT SO! But nope! A few minutes, or sometimes hours later, SAME PROBLEM happens on THAT card too! I swap it back again to the original/integrated NIC - Normal speeds again! Then again, few minutes/hours later, ping and download go to near nothing once more! I am finding myself having to swap between the two NICs (one integrated, one PCI) quite regularly when I see my bandwidth take a dump. And yeah, the computer is regularly rebooted 1-3 times a day too.

Oh... my... gosh! You have no idea how baffled I am! I have never seen something like this before! I have narrowed it down to three (unlikely) possibilities:

1. Modem (I don't see how)

2. Router (Going to try straight modem connection to internet this weekend, but again, I don't see how the router could be responsible for random bandwidth-capping to only this machine, and not doing it to the others.)

3. Motherboard - In case the issue was with integrated NIC - I went and bought a new NIC and popped it in - It's the NIC I mentioned above so if it could still be the MB I would love to know how.

ANY insight appreciated! Thanks!!!!
 
Yeah I did try that actually also with no luck - Used the new cable that came with the new card, plus tried different router ports. Good question though
 
Hi!

I know one possibility, which might seem pretty much grabbed from the air, so to say. Nevertheless - I've seen that computers have network issues (no-go or awfull rate of package disapearence) at certain locations due to a phenomena called "energy streams". Those "energy streams" are "lines" with a heavy energy field, which criss-cross the planets surface. For example, if your bed is on/partly on such a "line", you'll expierince some trouble with sleeping (morning headaces, tierdness after a supposingly refreshing sleep and so on) - some people are more receptive to this than others - or, as for computers, some might not work or work partly with problems. I'm not talking trash here - those "lines" (I call them that way, because I don't know any proper expression in english) are absolutely scientifically proven and doctors as well as technicians advise to avoid sleeping on these "lines" or putting any vital devices on them respectively.

So, what I'm saying is - try to move that computer to another place or change places with another computer - just for a few days to see if the issue really isn't something else than the one described above.
 
Interesting what edijs desribed to be "energy fields." I've had an interesting experience myself with radio. I turn a pair ordinary computer speakers to maximum amplification. Next, instead of plugging the audio wire into the computer, I put it onto a piece of non-coated metal (ex. computer back panel). Surprisingly, I can hear our most popular radio station in town with excellent quality!!!!!!!!!!!!!!!! When I moved these speakers and tried this at another location in the room, it didn't work as well and the quality was way lower.:mad:
 
I have had a experience like that as well... I had one pair of real Old-School Soviet production non-electromagnetic-isolated (ie when the speakers were near my CRT, the colors got all messed up - standart appearence) stereo speakers. The odd thing was that when they were unplugged (but powered, of course) and volume was turned completely down, I could hear something like a radio station (very, very faint, but fairly clear). Not a local one - trying all AM, FM frequencies, I didn't get such a station.

Later, it occoured to me that those voices were changing and always a dialoge was being led. Yeah, it's exactly what I wanted to say - my final guess is - those were intercepted cell phone signals.

Allright - that was for some weird things :D ; but if we're talking seriously - try to change that position and see how things change.
 
Since it's only one machine, I would look towards missing option #4: Operating system issues. If somebody's using your system as a spam relay, that would definately explain that type of behaviour. Have you tried sniffing the traffic with Wireshark? That might give us a better idea of what's going on.
 
Hey don't feel bad i have the same issue where out of nowhere my ping will spike to up around the 1000's

[ot]ehh, interesting. Could u by any chance direct me to a link of a publication about this or something? [/ot]
 
@ DaRuSsIaMaN

I reffered to that phenomena as "energy streams" because of their effect on both biological beings and machines. I found that a direct translation for them into english is "underground water (stream)" (and, since your nick is DaRuSsIaMaN, I assume you might speak russian - "жилка" - "zhilka").

You can throw a look in here. This is just a small article. The effects are so heavy that architects avoid building in places, having these underground water streams, because they seriously contribute to cracks appearing in the walls of structures + the effects can be felt exactly as heavy in the 1st level as in the 16th (measurements have been taken from within EVEN planes). That's a serious thing.

Scientists have no idea wether these effects are electromagnetical or whatever type... they just see the resutls.

Somewhat interestning. People are actually even working as "underground water stream detectors". :x:
 
Hmm strange. Thanks for the link. After reading your linked article I also found this wiki page (of course wikipedia has something to say about it lol), which offers more background info:
Geopathic stress - Wikipedia, the free encyclopedia

Definitely not sure I believe it though, lol.

And yes I speak russian and understand "жилка" :).
 
Well, I myself, have not experienced any great changes when moving off a supposed "stress" location. Still, my mother, did. As I mentioned earlier - some people are more sensitive to this than others.

Anyways, when nothing else helps, you gotta dig into some possibilities :) , so I just though that this odd network issue could be explained that way.
