50mb speed suddenly halved...

[schuey100]

Hey there

My speed has suddenly more than halved, my best speed now is 21mb, before calling Vodafone again (they said there was no problem...) I was wondering if someone could look at my power levels and see if there was anything glaring that stands out...

Any ideas? Help much appreciated!

downstream marginal high upstream could be a bit higher.....

why you callign vodaphone????????

edit: post your modem config just so i can check it aint been dociss file cock up

[schuey100]

Hahaha, whoops, meant Virgin of course ;)

Here's the config..

[Andrewcrawford23]

i thought you meant virgin just was wondeirng if you had really called vodafone i would have bene interested in the chat oyu had with them lol

ok... modme configs are fine

i am assuming you are testing speeds with speedtest.net?

[schuey100]

I am yes :( Just so weird because I don't see anything drastically wrong, I tried going wired, even changed ethernet cables etc but no luck.

[Andrewcrawford23]

try these two tests

http://speedtest1.virginmedia.com/speedtest

Username – trials
Password – Tr14lz57

http://mcs.lushsoft.com/myspeed/mycapacity_50mb.html

there more accurate, teh virgin one will test your connection most accurately as it in virgn interal network, the other uses udp so gives better test result of external network to virign

I'm in NW London and am getting crappy speeds to.

power levels fine mmmmm 32mb is quite a bit lower than i expect for 50mb

ill post some other tests in second

---------- Post added at 17:42 ---------- Previous post was at 17:41 ----------

run these tests please

for windows open command prompt

ping -n 100 bbc.co.uk
tracert bbc.co.uk
pathping bbc.co.uk

ill post another test ina minute or two

[qasdfdsaq]

Do this test:

http://mcslhr.visualware.com/myspeed/mycapacity_50mb.html

If your line capacity comes back at or near 50mb, it'll be a VM congestion problem.

[Andrewcrawford23]

download all these files at once you should be able to donwload 10 files at once if not you will have to tweak your registry which i will post if oyu need

once you have started donwloading them reort the mb/s or kb/s of each file once oyu have post it cancel the downlaods

i already said it above :p

[schuey100]

Here's some more screenshots for the two tests...Definitely not 50mb :)

[Andrewcrawford23]

nope try th fie download tests ad the comman promtp tests

[schuey100]

Well I'm on a Mac but I used network utility to get a tracer and ping, I could download all 10 files but it took ages to get them going, had to pause one or two and restart them.

[Andrewcrawford23]

it looks like congestion nothing you can do it peaks hours

[qasdfdsaq]

i already said it above :p
Oops.

the downstream power levels are too high...
but i dont think that would be cauing the pseed issues you have, seeing as your speeds seemed to be stuck at 25mbit(ish) it looks like you have QoS or similar enabled on your router

[schuey100]

Except it's not just during peak hours, it's like this continuously...

QoS definitely isn't enabled.

[craigj2k12]

could be a load balancing issues as you are only using 4 of the available channels?

You've lost me, I'm too much of a noob for that :) What do you mean and how would I fix it>?

[Andrewcrawford23]

you cant fix the mode automatically will do it to allow more channels as the upgrades are done

[craigj2k12]

really, what are you on about?

the VMNG300 uses a max of 4 channels, the superhub a max of 8

Where as area has been upgraded, there will be either 5, 6, 7 or 8 channels available, which are bonded and the load is spread between them, as you are only using 4 of the available channels, its a possibility that the load on your set of channels is higher than on the other 2.

The above however isnt likely as you seem to have a steady speed of around 25mbit. I meant to ask, are you using wireless? or are the tests run wired?

If wireless, then thats probably the problem

that kinda wha ti was saying :s

[craigj2k12]

no, you said it would allow more channels automatically, and it wont

[AndyCalling]

You haven't seen a tall black chap with a grey goatee beard fiddling with your street cabinet have you? He may have pressed the 'Half Speed' button instead of the 'Double Speed' button by mistake...

[Andrewcrawford23]

no, you said it would allow more channels automatically, and it wont

and i have said many times bfore i am dsylexica how i put things across a lot of time isnt right but i can assure you what you said is what i meant

[craigj2k12]

then pointed at the air with both hands.... lol :D

[thenry]

GINGER. :no: grey

[craigj2k12]

and i have said many times bfore i am dsylexica how i put things across a lot of time isnt right but i can assure you what you said is what i meant

you said "it will add the new channels automatically"

when the truth is: "it wont add more channels automatically"

so yeah you put it across slightly wrong :dunce:
