Slow upload speeds on 20meg
 

Hi,

Although I'm a newly registered member, I usually check on here if there's something wrong, and usually find help. But this time around I cannot seem to.

The problem is, I've been 20meg Virgin for well over a year now, and recently my upload speed has dropped from around 720kbps, to 150kpbs. Quite recently aswell, early January ish.

I've spoken to Virgin, they say it's my antivirus, which it definitely isn't because I've had it on since I've had Virgin Broadband, and my upload speeds have been fine, and it's recently dropped so it's definitely not that.

Any help? Thanks

Post what modem you have and your power levels from your config pages of your modem. The should be a sticker on the bottom saying what model.

Open a browser and in the address bar put or click the link > http://192.168.100.1/ the password and username are both root if required.

What I want you to post is the Downstream power levels including the SNR and the Upstream power levels for me thanks.

DO NOT POST YOUR MAC ADDRESS OR SERIAL NUMBER

I'm finding slow uploads on my 20Mbit too, when I had non-VM 20Mbit from 2 other providers I had 2.5Mbit upstream now I'm down to 768k ;)

Hi, thanks for the quick responce, but I had gone off and could not reply.

As for the Modem. There is no sticker or anything under the modem, but all I can say is it's a Scientific Atlanta modem. This one exactly...

Sorry if this was not what you asked for, bit a noob when it comes to modems etc. :)

Re: Slow upload speeds on 20meg
 

Your power levels appear to be fine, I would advise you to call Tech Support so they can run some tests on the connection to try and find the issue, possibly oversubscription on the uBR.

Re: Slow upload speeds on 20meg
 

uBR? What's that?

Any help?

Re: Slow upload speeds on 20meg
 

Brilliant, thanks very much for your very quick responses, but silly question, what's oversubscription? :)

Re: Slow upload speeds on 20meg
 

A UBR is like a big router that your modem connects to on the network, tech support can check if this is full to capacity or if some other issue is causing your problem.

Re: Slow upload speeds on 20meg
 

To many people on your uBR/exchange causing high traffic at peak times which can cause slow speeds.

Ok thanks, i will phone support and let you know what they say, thanks

Ring during the day to try and ensure a UK call centre.

Re: Slow upload speeds on 20meg
 

Yes good idea, thanks :)

Re: Slow upload speeds on 20meg
 

It's rare for oversubscription to affect upload and not download. Three questions:

How are you uploading?
Where are you uploading to?
Are your speeds affected at the same times of day, or is it constant?

Re: Slow upload speeds on 20meg
 

Hi, unfortunately, at the mo i am using torrent sites and utorrent
My speeds seem to be at all times with the slow upload speed.

However, i would like sign up to maybe giganews newsgroup but need advice as to exactly how to download from it, as i hear it's full speed and not tm'd.

Thanks in advance.

Re: Slow upload speeds on 20meg
 

Right. So it's your uploads through the torrents that appear to be being restricted? Have you checked the settings on your torrent software? It can be limited there. Furthermore, you may be saturating your upload as other torrent users download from you. It may well be that you aren't seeing your connection at its best because other people are making use of it.

When you're experiencing the slow speeds, could you go to the command prompt and type netstat -a ? That will list every active TCP and UDP connection. Approximately how many are there?

Re: Slow upload speeds on 20meg
 

The settings on utorrent i use are i set the speedguide to 20m.bit, set the download and upload to unlimited and that's about it really.

I used to upload at around 700kb/s but now it wont go faster than 70-80kb/s,
and as said before, d/l are at a max of about 500.

Next time i'm downloading i will type in netstat-a and let you know, but i really want to get away from torrents and use newsgroups, apparently they are much better, but have no idea how to start.

Thanks.

Re: Slow upload speeds on 20meg
 

How are you tracking the upload speed? Is this a field you're getting from your torrent client, or is this from a speed test? I'm assuming the former. It could, theoretically, be misreporting.

As for newsgroups, I'd say that google is your friend. Beyond any possible legal implications, I use USENET for conversation. Yous binaries types are sullying the good name of fair NNTP.

Re: Slow upload speeds on 20meg
 

Hi, i track the upload speed using speedtest.net, and utorrent.
Thanks, i will look into newsgroups.
