View Full Version : Internet Speed Slow

12th May 2008, 07:14 PM

I have a strange problem and was wondering if anyone can assist me.

From the start of this month, my internet speed has been noticeably slower on my mac, I had not changed anything on the mac or with my internet plan. On sites I used to get speeds of 150.0kbs to 200.0kbs I now get 40 - 50.

I am using a Dual 1.42 Ghz Power Mac G4, running 10.5.2. I use Firefox and Azureus ans use a Netcomm NB5 ADSL-2 modem Router connected via Ethernet.

If anyone has any thoughts or suggestions I would be more than grateful.

Go to Speedtest.net - The Global Broadband Speed Test (http://www.speedtest.net) and do some tests to see if it is really as bad as you think.

If it does turn out to be the case, it is possible that your ISP has changed the port speed of your connection by mistake. What sort of plan are you on? ADSL2? ADSL1?

That happen to me also with my downloads. I guy at work said to enable port triggering on the same port as the torrent client.
Tried it.
Viola. immediate increase.

You've probably not set a limit on the upload speed of torrents, so because it's flooding your outgoing connection, it consequently means incoming data is slow. This is due to all packets sending in return an "ACK" or acknowledgement packet. If sending this back is slow, then further packets are delayed.

Thanks so much for your replies, just a couple of things:

I tested my modem and connection on a laptop and the speed was perfect . . . . .

My speed is slow even when azureus isn't on.

Why not post your speed test results then? You really can't say that everything is perfect but it is slow. Surely you can see that it is a contradictory statement? :)

EDIT: using default Azureus upload speeds will destroy your connection (just too many packets). While I admire the work they (coders) do, this is one setting where they have it badly wrong.

Other than your upload speed killing the connection (as mentioned) - maybe try calling your ISP?

If a torrent app that you can control the uploads is required- try xtorrent. You won't be disappointed :thumbup:

This is what I got when I did the speed test, not sure what it means though.

Did you run the test with nothing else using your network connection?
What sort of plan are you on?

Sorry guys, this is the test with nothing else running. What I was trying to say in my previous post was that when I plug my modem in via ethernet into a laptop the d/load speed is normally what I get. but for some reason on my mac it is not and I have no idea why.

I haven't had my coffee yet this morning, so I'm a bit slow on the uptake...

Which results are from your Mac, and which are from the other laptop you referred to? Were both tests done using an ethernet cable connected to your modem /router? No wireless connections?

Is the slowdown ONLY when you have your torrent client running? All the time?

Sorry to be peppering you with questions - there's just not enough info (for me anyway) to try and guess what the problem might be.

The above results are from when i tested the laptop, it doesn't make sense as they are nearly the same.

I realise how strange this sounds but I will try and give and example.

If I use my mac with the ethernet cable connection (not wireless) and without the torrent client running and attempt to download a file from a google page the speed sits around 10-30kbs.

If I plug in the same ethernet cable into my laptop and attempt to download from the same site and same file the file will download in excess of 100kbs.

It affects everything, you tube clips and general web browsing.

I realise this is a really confusing question but it is really frustrating the hell out of me. And just to throw a spanner in the works I was downloading a torrent the other day and the speed got over 100kbs, so I quickly tested the internet again and the same slow speeds came up.

I hope this is enough info, I am happy to answer as many questions as is needed.
