You could, with Plusnet, take the 40/20 Mbps service . . .

I am waiting for a symmetrical offering to become available.

Yes I did wonder about that myself.

I'd check again at non-peak, just to make sure its not congestion.. either on the SVLAN or via the ISP..  and also just to make sure that any settings on the TT side have chance to catch up.

However, it should not...  and must not stay like that, because it means that if you download a file, or surf or stream HDD, then you are going to be limited to 20Mbps.  Whilst I appreciate it may still be more than what you were previously getting..  it means that you are not getting the full amount of what your line is capable of.  20Mbps on a line that should be able to cope with 86Mbps isnt right :/

[broadstairs]

Yes I agree. I've been doing a bit more testing and I get approximately the same download speeds on the TT Speed Tester and I have also tried with a cable direct into the F1000 rather than via my gigabit switch and even on wi-fi and all I get is about 20mbps any way you cut it. In the morning I'll test with the HG635 to eliminate any router settings issues and if I get similar speeds then I'll raise an issue with their support forum. I know both routers sync'd at 39998 kbps. My current SNRM is 18.4db down and 24.3db up. I do wonder if my profile is correct since the max I would have seen on ADSL2+ would be about 20mbps but that does not explain why x6 download on TBB gives me a much higher speed.

try adjusting the mtu to 1492 as 1500 will only work properly with jumbo frames on pppoe.

1500 is standard ethernet mtu, it should not require jumbo frames (7500 or 9000 are jumbo frames)

[broadstairs]

Well 1492 or 1500 makes no difference.

I just looked at the logs of the ZyXEL and about every 2 minutes I see a set of entries like this:-

Code: [Select]

Any idea what this means?

I have this morning tested my connection with the HG635 instead and it made no significant difference to the TBB Speed Test so I have put back the ZyXEL. I have run the TT Speed Tester as well and that show I can obtain a download speed of 29.35mbps but they do not explain what kind of transfer they are using but even on that I still feel it is under performing.

I have created a thread on their forums asking them to take a look. We will see what happens.....

Netmeter is a good tool to have to measure throughput speeds
http://www.metal-machine.de/readerror/index.php?action=tpmod;dl=item23

Then grab one of the files from TBB http://www.thinkbroadband.com/download.html and watch what Netmeter records for a single thread.   Its also useful to monitor bandwidth for such things as HD streaming etc. 

Also an excellent site for diagnosing throughput issues is http://myspeed.visualware.com/index.php
Run some of the advance tests such as 'Quality' and it will tell you if it suspects things like MTU or QoS or congestion problems.

[broadstairs]

Netmeter wont be useful for me as I run Linux. Running it under a VM will not be a reasonable test. The visualware stuff seems to show a higher speed download right now giving between 27 and 30mbps.

ifstat or iftop for linux

[roseway]

... or better still, dstat.

Interesting a different speed test result using Chrome rather than Firefox....



Stuart

[broadstairs]

Just to prove it was not a fluke I have repeated the TBB speed tests on Chrome and then FF and on a sigle download FF gets about 20mbps and Chrome see about 29mbps so it would seem that There is a problem with FF at least on Linux and the TBB speed test (the one using Flash). There is still a difference between the single and 6x tests on Chrome, 29mbps and 37mbps respectively.

While using the HG635 TT want me to turn off the router for 30 minutes and then power it back up to see if it makes any difference, dont see why this might make a difference but hey I'll give it a go...

I wonder what you might see if you try http://labs.thinkbroadband.com/ispa/  ?
