has anyone noticed that ooklas resulits are very erratic lately.
going from 4mb download and 30 mbs a minute later.
that sort of thing.
i have recently been upgraded to RBI 4G.
my upload is often faster than my download.
just before down was 27mbits and up was 29 mbits
why would this be

Are you testing over WiFi?

When I test over Wifi, I have erratic results.

I also see wild swings up and down on the "grunt-o-meter" as it's calculating the speed.

i rung vodafone tech and they said they would check it out.
it is cycling
if the down load is 27 mbits about 80% runs through fast , then it stalls and goes real slow till it finishes .
the upload will then be about 2mbits.
if i go test again it will be on about 2 or 3 down and 27 mbits up.
next time it will be on the next cycle.
it is like someone is repetitively up and downloading large files and jaming the network.
we are remote rural with an aging population, a lot of who do not even text, so i am thinking it must be a business.
i did not notice it on 3G, but i was not looking.
i will see if it is happening tonight

Does it matter? Is your Internet connection generally fast enough for what you do?

Mobile data ramps up. If it was sitting idle before test, then it takes slightly longer to start ramp up. The speedtest will think "slow connection" don't send too much data. Won't ramp up enough to do a decent test. Next test, connection not idle, starts fast, speedtest thinks hmm fast connection I better send heaps of data, connection ramps up a lot more.

Thank you. For info
It is fast enough.
But I realise just because it is 4G does mean.if I am watching light box and my husband is playing games and my son watching utube and our weather.station and weather cam uploading, that it is not going to have a moment

If you are on RBI you cannot expect the connection to perform to the same levels as a wired or fiber connection does.

It would be interesting whether the slow down is consistently at a similar part of the test (e.g. 80%) which could indicate some traffic management is being applied. If random (e.g. sometimes gets full test at high speed) then more likely to be other user activity. Any comments from Vodafone?

I honestly don't know if VF do any form of traffic management, but in general, it should be the last thing anyone thinks is an issue with BB in NZ. Seriously, in nearly every instance it's going to be something else.

I just don't get it.

it is consistently in the same part of the test if it slows down from a 20 mbits plus speed.
my LTE phone connects at 50mbits a second to the same tower.
i have 4 bars of signal and an rssi of 57 on RBI
i am line of site 6 klm from the tower
did test today and download was 2mbits a second and half an hour later 28 mbits
my 4 G signal and coverage much weaker than my 3G

It is a bit strange you seem to be getting two separate quite different answers. Another type of Speedtest may be worth trying. SpeedOf.me (that's the URL) works differently and while it is probably sourced from Sydney could still be useful.

This could explain variability with an increase during the test but the reported symptom is slowing down after a certain amount of traffic has been downloaded. Could still easily just be other activity on this shared access starting up but may be too repeatable for that explanation.
