Why is it when I upload something the internet drops to 0/Kbps?

I think it's worth it. They're Mac people as well.

Not the same thing. Speed issues are affecting ADSL2+. My and Netgem21's problem is that we can only upload or download, not do both at the same time.

That is most odd, things are fine here, so contacting support would be prudent, odd how some people have issues and some do not, the vagaries of the internet. It's nice and sunny outside though

Below is my speedtest data whilst uploading to mobile me,something's going on looking at the ping result,see signature for earlier result.

Just repeated the test with another upload to mobile me and a completely different result which looks normal whilst an upload is in progress.

Tried several more speedtests whilst a mobile me upload is in progress the above pattern is repeated for me some normal and others respond with the very long ping time. Whether this is specific to mobile me or due to the fact that an upload is in progress I don't know.

Pings will increase during large downloads, Steve, so it's likely to happen on uploads too I suspect.

Steve · Jun 17, 2009, 08:57:06

I agree you need to able to control the upload bandwidth (like P2P software can)to permit a useable connection, if your upload grabs the majority no other use is possible.

Update:

Contacted support who, after going through all the "try different machine, router" etc., checks which made no difference, are stumped. Apparently it shouldn't be possible for uploads to severely limit downloads. They do though

Support are (were) unaware of this thread, so anyone with a similar problem should contact them please.

Rik · Jun 17, 2009, 18:14:49

They've had their hands a bit full this week.

I haven't checked every post in this thread so I may have missed something... have you checked that

SysPrefs => Network => Ethernet => Advanced =>Ethernet => Duplex

is set to full-duplex, flow control?

If it's set to half-duplex I'm not sure if it will cause your problems, but it sure won't help!

Dopamine · Jun 17, 2009, 20:46:09

Where do I find SysPrefs?

I haven't checked it, but the problem is occurring on three different PCs, still occurs when the router is changed to an alternative, is the same on XP and Vista, and only started 24 hours ago. I can't believe it's a machine issue, but anything is worth a try.

Ah, I should have read more posts... I thought you had a Mac. Sorry

Just did some post-interleaving-activation speed tests. Here are the results:

Test1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 8128 kbps(DOWN-STREAM), 448 kbps(UP-STREAM)
IP profile for your line is - 6500 kbps
Actual IP throughput achieved during the test was - 4920 kbps

Also, I'm still having the problems with upload/download performance.

Rik · Jun 18, 2009, 16:49:03

Your profile hasn't caught up yet, it will move to 7150 over the coming days. I really don't know what to suggest on the performance issue. Do you run something like NetMeter (if there's a Mac equivalent) so that you can see the actual traffic levels?

Me too. Support don't understand the problem and are apparently contacting BT. In the meantime, my download speed has dropped badly. BT speed test just showed 2177kbps throughput for a 7150 profile.

What pipe are you on? I'm .net, having been moved from gw6.

I have no idea how to find that out - all I know is that my username ends in .dsl4

Simon · Jun 18, 2009, 17:03:07

That's it, so you're on the DSL4 pipe.

I've emailed support about the performance. The only thing I can show you is traffic over my wireless network - I don't know any software to give me graphs on actual internet speeds.

Sorry, I'm only any good at the bleeding obvious.

It seems you're on a different 'pipe' to Dopamine, but I wouldn't like to say what it means.

Big time, dsl4 is only for the premier customers.

Seriously though, there shouldn't be a difference between the pipes.

Rik · Jun 18, 2009, 17:28:31

My gut instinct is that something in the machine is maxing out the processor.

I've discounted that by uploading with one machine and simultaneously downloading with another. Whenever an upload is in progress, downloads are severely slowed. Absolutely everything has been changed: routers, filters, PCs, operating systems. Very, very frustrating.

Rik · Jun 18, 2009, 18:22:29

I can understand that, Dopamine, it just doesn't make sense.

Steve · Jun 18, 2009, 18:22:35

Certainly activity monitor on the mac and task monitor on wibdows will give real time measurements of CPU ativity and which process is using what.

I had very poor speeds on .net yesterday evening until quite late which is unusual. Unfortunately today the prodigal son has returned so P2P is running so unable to comment this evening.

Do you know the rate of upload ? From my own line any signifant uploading via P2P has always made my connection unusable.

Dopamine · Jun 18, 2009, 18:33:47

My upload is always at full speed, around 400kbps.

My .net pipe was showing peak time congestion yesterday evening too, and has been slow this afternoon since about 4:30pm. Support say their network isn't congested, BT say my exchange isn't congested either, so someone is wrong. Presumably, all those moved from gw6 to other pipes must have placed additional burden on those pipes, so does anyone know whether gw6 is back on stream?

Simon · Jun 18, 2009, 18:49:18

I think only IDNet would be able to tell us that, Dopamine. It does seem a very strange problem, even more so that only the two of you (on the forum) seem to have been affected by it, and you're both on different pipes. I can understand the frustration.
