CA3LE reacted to xs1 in 0.15 Mbps (day) to 102.9 Mbps (overnight) - Major fluctuations and high packet loss - Suggestions?

I see what your ping plotter is saying, but what's up with the latency results?? Other than to google and amazon, your latency is outrageous just about every where else! I almost wonder if you have a bum splitter somewhere causing all your irrationalities.
Here's a latency test i just took..
CA3LE got a reaction from dncellisd in How much speed variation is acceptable?
First, I will be changing variance to standard deviation in the future.
Let's use this result of your as an example.
TestMy.net Test ID : 5zlOE7tGc
Ideally this flat lines and doesn't deviate from start to finish. Sometimes though, if the result is much lower than your line speed this flat line can be an indication of a bottleneck. Most of the time a flat line with 0% variance is a good thing.
One of my recent results as an example.
TestMy.net Test ID : fUJ4g~VHj
Here's the actual calculation from the program.
round(($maximumThruput - $minimumThruput)/(($maximumThruput + $minimumThruput)/2)*100)
So your example above would be
round((0.32 - 8.32)/((8.32 + 0.32)/2)*100) = -185%
The difference from the min and max divided by the average of the min and max... then calculated into percent.
The higher the number the more it indicates that the connection was heavily fluctuating during the test.
Using standard deviation from your example above you'd get 2.4 Mbps [https://testmy.net/working/deviation/standard-deviation.php?arr=3.28,2.91,1.79,1.84,3.04,4.93,1.43,0.32,0.34,1.31,1.91,3.34,1.89,1.73,3.9,7.28,8.32,8.18] -- Again, ideally this number would be 0 Mbps.
My result above's standard deviation is 42 Mbps... higher number but not relative to the result. [https://testmy.net/working/deviation/standard-deviation.php?arr=155.34,345.77,338.49,338.49,340.88,347.01,334.96,331.51,338.49,338.49,345.77,349.53,348.26,342.09,348.26,347.01,339.68,343.31,344.53]
So the standard deviation then needs to then be turned into a percentage of your average.
$standardDeviation / $middleAverage
Your example: 2.4/2.93 = .82 ... or 82% My example: 42/342.24 = .12 ... or 12%
Using standard deviation I think will be much easier for everyone to understand. To understand the current formula myself I had to go into the program... my users don't have that luxury.
Long story short: Variance shows what I wanted to show but makes it overly complicated. I'll work on that for you.... actually -- I kinda just did, just need to work that all into the program.
CA3LE got a reaction from dncellisd in ISP Provides Continuious Run Around
WideOpenWest (wowway.com) is a cable provider, right? You use a cable modem connected with coaxial cable, correct?
Just because you haven't touched anything doesn't mean that you don't need service. I'll explain a few scenarios...
1) When you were originally installed the tech may have seen low levels and needed to amp the signal... good at the time but what happens if the feed signal levels return to normal? ... it becomes over amplified and actually degrades signal.
2) Or the opposite could have happened, the tech may have seen signal levels that were too high and needed to purposely drop the signal level. To get the optimal service the levels need to ride in a zone. Techs will purposely add splitters or DC taps even when they aren't necessarily needed for splitting or tapping. ..... but then if the feed signal levels return to normal levels the customer can have issues.
3) The barrel connectors in your wallplates, your splitters and the cable and its connectors can have issues too. Especially if they run on the outside of your home. Weathering of the coax and internal oxidation of the splitters ruins signal. I've seen many splitters that looked perfect from the outside... crack it open and it's all rusted and oxidized all over the internals. They can also pass your TV signal fine but have issues with JUST the frequencies that the cable modems use.
4) Something as simple as a 90 degree kink in the cable... happens a lot. People don't realize that coax can't cut corners like that.... they try to mold it around sharp corners and the sharp bend causes the signal to echo within the line. I've even seen electricians do this! RG-6 must maintain 75 Ohm impedance to be effective.
How much bend is too much. Coaxial and optical cables are rated for bend radius, some can bend more than others before the impedance is affected. A good rule of thumb is that you take the OD (outer diameter) times 20. RG-6 is the most common coax cable, which has an OD of 6.8 mm (0.27"). 5.4" would be a safe minimum bend radius.
5) Another commonly overlooked cause is a tiny tack or nail puncture or pinch the line.
First the outside, sometime contractors, electricians and do-it-yourselfers will use the wrong kind of staples...
Even that little pinch in the coax can cause echoing within the line. Sometimes they staple right through the cable (seriously, idiots), I've seen it dozens of times. What are they drunk or something?
Types that I use...
for concrete for wood
Many types are great, I use anchor and screw type in some situations. The point is to again, maintain that impedance... nice round cable with no kinks.
Inside, 'carpet fishing' (where the cable is hidden under the carpet) can be an issue. People who run cable this way don't usually think about the carpet tack board, you need to hammer the nails down at the entry points otherwise it will puncture the cable and turn the little nail into an antenna to the outside... leaking air signal into the cable and destroying your cable signal. This is definitely a scenario where things can be great one minute then bad the next. Could sit fine for years with the nail just resting on the outside of the cable, then you're moving furniture or something you bump it just right...
The possibilities of what the problem could be are endless. Could also be your equipment... or something as simple as a signal level adjustment at the tap... or the drop to your home could be damaged.
Good luck, I hope that it gets fixed soon and you start getting what you're paying for. Let us know how it goes and what they find.
... by the way, Welcome to TestMy.net!
Have you tried hooking up directly to the modem, eliminating the router? Try that before you call them. Hook it up to ethernet, directly to your computer. Unplug the modem for 10 seconds and plug it back in... give it a little bit and retest once you're online.

I'm a Telecoms Engineer for Wightfibre, based on the Isle of Wight.
We have been rolling out our own fibre optic network for the past two years.
I'm currently testing 10G to my home, which was installed with fibre not long ago.
This is the fastest test I could do until it told me it was fake! (Rate limiting)
I can provide further proof if you require
CA3LE got a reaction from mudmanc4 in Speed test doesn't complete
The automatic speed test communicates with the server you have selected outside of its normal test sequence... it's testing your latency in the background.
When you're using this test, you shouldn't be surprised when my servers talk to you... it's how the test works.
If you think I'm doing anything malicious... don't use my program. You always have control over turning it on and off.
Fact is, all my code does is try to help you improve your connection. Dig apart the client-side code as much as you want... as with any good program it only does things you ask it to do.
I've been doing this for over 20 years, I respect my users and value their visiting and sharing my resources. I wouldn't do anything to jeopardize my users or the trust and reputation I've built. I wouldn't anyway, "Do unto others as you would have them do unto you."
.... it may not have done that for you in the past because you weren't a member. You have to be signed in for that feature. If you think your wireshark is going nuts now you should see what I'm building.
CA3LE reacted to JereSalo in Different download speed in Laptop and PC
Hi! Thank you both for your help.
I solved this issue 2 days ago, I had a problem in my Windows 10 desktop and I investigated it for a few days till I found this:
I wrote this on my CMD: netsh interface tcp set global autotuninglevel=normal
And it worked!
Now if I run the test on my desktop pc I have more than 30Mbps and before I had 3. I don't know why Windows was configured in that way.
Have a nice day and thank you for your time!

Is your laptop also Windows 10? I'm trying to differentiate your results. If you go to https://testmy.net/mysettings you can select an identifier. Do this on your laptop and desktop to help sort the results.
Unless your problem has been resolved I'm going to guess that this is your laptop...
TestMy.net Test ID : Qdf6F52b4
... and this is your desktop...
TestMy.net Test ID : otO225XBt
Looks like you're in Buenos Aires, is that correct?
How old is that desktop computer? Similar in age to the laptop? Have you seen connection speeds that you'd expect to see using that computer in the past?
You mention antivirus... have you tried disabling all of that stuff to see if maybe that's the thing holding you back?
When all else fails you can try a refresh, reset or restore. [Please read and understand what you're doing first.] I would suspect software issues before I'd look to the controller, cables port or router. (based on the info you expertly provided) Personally, I like to do a complete re-install of windows every 6 months to a year... even if I don't have issues. As windows takes on some of the changes slated into the future I don't see this being necessary moving forward. But right now... it still benefits from a fresh install. Especially if you use that machine a lot. Windows just becomes a steaming garbage pile after enough use...... again, I don't see this being an issue in the future with the changes windows has in the works. But we aren't in the future, yet. ... OSX and linux don't have that issue. 100% of my OSX fleet have never had the OS re-installed. Some still working perfectly snappy for well over a decade. My windows machines are constantly being re-installed, otherwise I feel it.
And I'm not anti-windows or pro-mac... in fact I have a big fat bar of black tape covering the glowing Apple logo on the laptop I'm using right now. I'm just pro-having a computer that works correctly. Windows has done that for me in the past, Apple does that for me in the present but I have no allegiance to either into the future. If the SchwettyBalls Pro (or whatever) came out and made my job/life easier I wouldn't care what the name is... as long as it does exactly what I tell it to do better than the others.
Please let us know if this helps.

CA3LE reacted to bp3 in large up/down speed difference between laptop and phone?
Its a new 2019 macbook - so it has no ethernet port - probably some dongle I could get... I did manage to get it up over 200 Mbps by moving from 10ft away to right over my wifi router so definitely something going on there. Maybe my router is 'intelligently' limiting it or something. Anyways thanks for the suggestion!
CA3LE got a reaction from Vitorio in Difference Between Speed Test Sites?
Yeah, companies always get away with stuff in the fine print. The best we can really do is try to educate people on their practices and recommend ISPs with better practices. I just hope that the information here has and will continue to help make the internet a better (faster) place.

It was failing everytime but I just ran it twice now and got my combined results. I will keep testing. I don't think the code has a bug per se just that in India where my connection is so variable I think a more robust way of dealing with errors would be good.

Hi DJ, Welcome to testmy.net!
Yes, that's all still accurate. Millions of people still regularly use TMN, only a small percentage are members. An even smaller percentage of members actually use the forums here. Before facebook, these forums were much more popular.
To legitimize any of my statements all you have to do is search the internet. I feel that other people have scrutinized and legitimized what I'm doing over the years, my methodology and core principals never change. Many have put TMN under a microscope. In my development I put it under a microscope too. Maybe I should post more of those findings but if I focused my time on that... it would have to come from somewhere. I think it's better left said by other people.
Funding comes from generous support from viewers like you... just kidding, PBS quote. I have ads. Maybe one day I won't have to.
