Why is my download speed only 1.5MB/s?? Open | Networking

It’s just an Ethernet cable that runs to my pc but It’s always been capped around 1.5MB/s

Are you sure you're paying for 25MB/s (megabytes per second) and not 25mbps(megabit per second) one megabyte is 8 megabits.

56

u/Upper-Job5130 Oct 16 '22

Even worse, if you're paying for 25 mebibits per second, that's just shy of 3.3 megabytes per second.

36

u/TaxOwlbear Oct 16 '22

And it's probably "up to" and no actual guarantee.

10

u/fiddlerisshit Oct 17 '22

It is not probably but always "up to". I have never hit the advertised speed on any ISP or telco.

3

u/RandmTyposTogethr Oct 17 '22

On the other hand, I've hit it quite constantly. But definitely "up to". Often there's some minimums they must meet but that also depends on country and ISP

u/bretto2004 Oct 16 '22

... you're still waiting for somebody to argue mebibits, aren't you? /s Lol.

4

u/HalfAnOhm Oct 17 '22

Absolute worst case scenario, you’re paying for 25 meganibbles per second, which is 50 megabits, or 6.25 megabytes per second, respectively.

Always read the fine print…

u/ZoixDark Oct 16 '22

What do you get if you use speedtest.net?

u/AndrewFrozzen Oct 16 '22

Speed test is half-bad as a tester.

They run a internet speed test but it's converted in Mbps, which, mind you, is not the same as MB/s

They are Megabits per second, not Megabytes per second.

So in my case, I get 100Mbps on there. Converting the numbers it gets me 12.5 MB/s

99

u/Elrandra Oct 16 '22

It's always been this way...What you pay for is also measured this way. When they tell you your speed is 100, it's in bits not bytes. It's not bad as a tester at all. It shows you bits because it's there to test that you are getting the speeds that you are supposed to, which are advertised to you in bits. If it converted it to bytes, there would be a ton of people complaining that they aren't getting the speed they pay for, because a lot of people just don't know it is done this way.

-97

u/AndrewFrozzen Oct 16 '22

It's half-bad, well half-missleading might be better words.

And I never said it hasn't been this way. It always has obviously.

And now they won't switch over to MBs because it's more convenient for them, more numbers, bats and eye more often.

Speed test is good, but it can be a bit misleading.

53

u/ZoixDark Oct 16 '22

Everything networking has been measured in bits since the beginning of time. I pay for 1gbps and I get 1gbps. I'm asking OP what speedtest gets to see if they say 25 or 200.

-66

u/AndrewFrozzen Oct 16 '22

And I never said it hasn't been measured from the beginning. I was agreeing with you two. You can make the conversion obviously but OP probably or others didn't know that. I was speaking for others thinking "Oh it says 100 on speedtest but I get 12" I was confused too.

27

u/Hamshamus Oct 16 '22

But why are you converting to bytes at all?

-3

u/AndrewFrozzen Oct 16 '22

They are easier and most Launchers like Steam and Epic and Battle Net use bytes.

22

u/Hamshamus Oct 16 '22

Does your ISP advertise speed in bytes?

-5

u/AndrewFrozzen Oct 16 '22

No, they advertise in bits because they are bigger numbers.

As I said, 12 Mega Bytes per second is 100 mega bits per second.

u/GOKOP Oct 16 '22

They show bytes because they're downloading files, which after being saved on your disk always take a multiple of a byte. Measuring network speed in general in bytes is meaningless

12

u/mrjimi16 Oct 16 '22

That isn't remotely misleading. Internet speeds are advertised in Mb, so it actually makes more sense for them to use that, along with the fact it has been industry standard basically as long as the industry has existed.

u/acr_8133 Oct 16 '22

if you really want to know...

bats and eye should be bats an eye. sounds almost the same but not quite

boneappletea should be bon appetit. again sound almost the same but not quite

dont know if i make sense, english isnt my first language

u/AmyIsabella-XIII Oct 16 '22

I was thing it was meant to be bats an eye, but I couldn’t make sense of that either in context. Thanks for responding!

u/Galotex Oct 17 '22

How is it misleading lmao

u/ThePantyArcher Oct 17 '22

Under settings you can change it to MB/s i believe. You might have to log in.

u/0mni000ks Oct 17 '22

by this logic arent the only ones being deceptive/misleading the ISP?

1

u/AndrewFrozzen Oct 17 '22

Not wrong, that's why I said "half-missleading" for Speed Test.

Because they just follow what the general people do. ISPs are the ones that won't change it. Speed Test are just following suit

u/pringles_prize_pool Oct 16 '22

speedtest-cli allows you to output Bps instead of bps, if that would be more convenient for you 🙃

u/iAmmar9 Oct 16 '22

You can change it on the website too iirc

u/totally_not_martian Oct 17 '22

Uhh you do realise that internet services are sold in megabits per second not megabytes right?

2

u/FunkTrain98 Oct 17 '22

That’s exactly how it works though?

24

u/atlienk Oct 16 '22
  1. Do you have another machine that you can use to test? There’s a small chance that your machine has negotiated the wrong speed.
  2. Though, the more likely scenario is that your ISP is throttling you so confer with them. Also, try a few different speed test sites before you do to confirm your results.

u/delcera Oct 17 '22

Literally nobody in this thread trying to attack the issue instead of the terminology.

Try a new Ethernet cable. If yours has a bad pair it will cap your speed arbitrarily; I have a gigabit line at my house but my desktop only gets 100 meg. I know for a fact it's a bad pair (because its a flat 100 mb) but I'm too lazy to climb into the attic to fix it.

You can get a new cable at Wal-Mart for a tenner, and it'll be a lot less hassle than bitching your ISP out for a bad connection. If the cable doesn't fix it you're out nothing because a spare Ethernet cable will come in handy someday (I promise; learned this the hard way) then try the following:

1) reboot your router and modem. Physically remove the power cables for at least 10 seconds when doing so. Your router is a computer too, and it can start acting up just like your desktop can. And your modem, assuming you have cable internet and not dsl or fiber, can build up interference at the cable connection which will cut your speed. Removing the power clears it.

2) check that you don't have anyone or anything using your bandwidth without your knowledge. Check the devices connected to your WiFi as well. I've had neighbors "borrow" mine and tank the speed by running Netflix and stuff.

3) check that you're not connected to a VPN or similar.

4) call your isp, tell them that you've done the above, and they'll take your report seriously instead of just blow smoke up your ass.

u/Shivaelan Oct 17 '22

I’m glad someone said this and actually answered the question.

A new cable is where I would start, because cables DO go bad and that’s probably the simplest solution to start this round of troubleshooting. From there, basically follow the steps above; I’ve worked in IT on and off for 20 years and this is what we do to make ISPs properly escalate issues in the ticket system so they can get handled. If you’ve checked everything on your end, then they’ll have to eventually fix their issue.

I’ve also seen folks recommending speedtest and such on here - remember that these are extremely popular tools that have blown up into the mainstream consciousness. This means your ISP knows about them too, and will artificially inflate your results on those sites to prevent you from realizing just how bad your speeds are.

2

u/RandmTyposTogethr Oct 17 '22

Well, they don't fake the results, they just connect you to their Speedtest servers next to the switch your connection terminates to so the results seem better than what you get in real world. You should be able to force a select server to circumvent this though I think?

2

u/Shivaelan Oct 17 '22

You could once, not sure now as I’ve transitioned out of IT but largely we weren’t directing clients to do that as most of them would likely find trouble getting out of a paper bag. Regarding that, thanks for cleaning up my reply; it never turns off, but the second I open my mouth I’m back in “teach grandma about the power button” mode.

12

u/TigTex Oct 16 '22

You are probably mixing bytes per second and bits per second. Internet speed is usually in bits per second and most software displays speeds in bytes per second. 8 bits = 1 byte so you need to convert the units.

1.5MB/s is usually the speed that an ADSL modem gives you when it's synchronized at 16mbps. If you are using this technology, you are lucky to get that much speed.

5

u/mrduncansir42 Oct 16 '22

Is it only your PC that gets the speed capped? What about Wi-Fi on other devices?

3

u/MCwMS Oct 16 '22

u/Background_Success61 - while there is lots of debate about the measurement of bandwidth, what are you trying to download that seems capped at 1.5? Specific site, anything, everything? What else have you tried?

u/Oasis0 Oct 17 '22

I'm guessing it's a steam game, which would explain why it's lower than expected.

This. Until we know what you’re paying for, we can’t really say if what you’re seeing is right.

u/jomjomepitaph Oct 16 '22

ISPs usually sell their internet in Mb/s not MB/s

27

u/y0um3b3dn0w Oct 16 '22

I have never seen download speeds advertised as MB/s. However, even if its mbps, you should still get around 3MB/s

14

u/Drevway Oct 16 '22

Aaand they usually advertise a theoretical maximum and not what you usually get IRL. OP should also look up the guaranteed minimum in the contract.

5

u/y0um3b3dn0w Oct 16 '22

I've always got within 95% at the minimum of the advertised rate. Majority of time it's more than advertised rate

-1

u/nikhoxz Oct 16 '22

Idk, in my country, by law, they can't advertise more than what they can guarantee.

So there are not "up to" speeds, what you pay for is what you always get.

7

u/mrjimi16 Oct 16 '22

If it actually is Mbps, considering overhead and that you'll never actually get close to it, I'm not sure 1.5 MB/s is that unreasonable.

-5

u/y0um3b3dn0w Oct 16 '22

That's pretty much half of what he should be getting. I'd say that's pretty unreasonable

3

u/mrjimi16 Oct 16 '22

Half of a small number isn't that big of a number itself. Whatever his package is, it isn't uncommon to not get that number, so we can drop a little bit while being reasonable. Network overhead will also eat up a bit of it. For example, I have a storage server. My network is on Cat6, my switch is gigabit, both my computer and server have gigabit networking, and yet when I copy things between them, the best speeds I get waste nearly 150Mb out of the 1000. Not every one of those bits is transferring data, a good chunk can be just facilitating that transfer. Frankly, they didn't give nearly the kind of information necessary for us to make any real diagnosis.

3

u/cinyar Oct 16 '22

do note that you're most likely paying for "up to" 25. Very few (if any) ISPs offer guaranteed speeds as default. Back when I worked for ISPs you would pay a hefty premium for "at least" 25. So check your contract for the wording and "guarantees" they make.

3

u/kushari Oct 16 '22

You’re paying for 25 Mbps not MBps. The b being small is bits not bytes. Everything in networking is measured in bits. You need to divide by 8 to get your download speed in Bytes, as there are 8 bits in a byte. So your maximum theoretical download speed is 3.125MB per second.

6

u/Dingdongpro Oct 16 '22

I would contact them and ask for an tech support to come over and see what’s happening.

u/greyflam Oct 16 '22

Your ISP should be able to run a line test to see if it’s a problem with the line or with your equipment

1

u/unevoljitelj Oct 16 '22

25MB/s is roughly 200megabits, so you are paying for 200megabits per sec or 25megabits per sec? 25megabits per sec is not much but its better then nothing.

1

u/FunkTrain98 Oct 17 '22

You’re paying for 25mbps. That’s about ~3MB/s. So yes your speed is slow, but that package won’t ever be “fast”

u/mossipb Oct 16 '22

Yeah op unless you are getting symmetrical dia connection that is 99.9% MBps you are only going to get best effort mbps for most ISP’s

1

u/Crimtide Oct 17 '22

25 MB/s is not what ISP's rate their subscriptions on.. I think you are confused.. 25 MB = MegaByte (big B).. 25 Mbps = Megabits (small b).. 1 Byte = 8 bits..

That being known.. 25 Mbps / 8 = 3.125 MB/s is your MAX capable download speed.

Downloading @ 1.5 MB/s seems correct in the sense that you have other devices on your network using the internet, and even your own computer running services using the internet..

2

u/razenet Oct 17 '22

1.5 could be true if they are getting half duplex. And with a 0.94% to account for overhead it would be 1.46.

OP. I would double check your router model to see how old it it and if your computer or router are connected to half duplex.

u/theoriginalwesh Oct 17 '22

Do you have Comcast?

If so then they'll throttle the shit out of you. I speak from years of experience....

u/toybuilder Oct 17 '22

Ethernet cable... Unlikely, but just to be sure, you're not using an old Ethernet cable, are you? Older cables are likely to have signal degradation issues that prevent reliable high speed operation.

1

u/homiecydxl Oct 17 '22

You’re mistaking Mb/s with MB/s. What you’re getting is accurate to what you pay for.

1

u/MrLeapgood Oct 17 '22

You might have a bad cable. I literally fixed this problem last week. My cable went bad (or was always bad and I didn't notice) and my Ethernet was capped at 10 Mb/s.

I figured it out by doing a speed test with my phone on the WiFi network, which came in much higher than the Ethernet connection. Although that still might not work depending on the cable between your modem and router, I guess.

u/RandmTyposTogethr Oct 17 '22

ADSL? Old modem? Has it ever gone over 1.5? If Speedtest gives you 12 Mbps and you pay for 25 Mbps, then your modem needs to be replaced to a newer model, or just reconfigured

u/ClaudeVS Oct 17 '22

u/IgazHarcos Oct 17 '22

Make sure to check if your adapter is set to 1000Mb/s. For some reason mind was set to 100Mb/s defaultly.

u/andredewerdt Oct 17 '22

How anyone can get things done at those speeds.... Living in Europe, moved from NL to FR... Went from 600mb down/50mb Up to 800mb symmetrical.... and that for € 34 a month.

But actually trying to resolve issue (from easy/ less hassle to doing actual work) - reset modem/router/pc etc (1min) - try other PC /laptop (5min) - try/buy other cable (30 min) - call ISP (days)

u/StopLurkingTakeTheL Oct 17 '22

So uhh I just ordered 500 Mbps what kind of speeds should I expect from spectrum fiber optics please tell me I didn't get screwed I wanna become a streamer/ I play PC alot

u/Intelligent-Way1288 Oct 17 '22

If you want a 'fair test' this is what I recommend: firstly log out all devices using the router and access points - make sure you desktop/laptop is the only connected device. Disable proxies and vpn on your devices if you have any, use dhcp on your router and/or device... wherever it's applicable.

Update router and device firmware / os if required.

Close all apps and clear chaches on your device. Then test speed: Ooklah is an 'ok' app to use to test speed.

If the problem persists, chances are it's down to faulty router hardware, or perhaps there's a problem with a junctionbox if you're using something like FTTC internet. In this case best to contact your service provider to get a field engineer to test hardware and local exchange points.

In the mean time, as other are saying re-read the providers T&Cs. Getting 1Gbps doesn't mean you'll by getting this consistently or even regularly, but may just indicate peaks. Change service provider if above does not work and if in doubt about quality and integrity of services here.

I'm not a professional but this is what I would do.
