I havent jelv.   My nettage seems real screwy tonight.

Ive not really used the internet since I tested the settings on Saturday, and although Ive put everything back how it was, its being a right PITA and I cant get pages to load properly.  I can get to google fine, but if I click on a link it just sits there waiting forever for the page to load, anything cached is ok.  It feels like a DNS issue (which is why I visited the PN forums & saw the parental control post there), but Ive changed to googles DNS servers and Im still having the same problem.

Its totally doing my head in. 
The fact that I havent used my PC over the past few days, means I cant for certain point the blame at changing the parental settings being the cause...  because I dont know when the DNS-like slowness exactly started.

Damn i cant get stuff all on the ipad..   Ive 'broken' my internets
nor if I amend this post can I see any amendments..  I guess Im just seeing the cached page.

...and on that note Im off to watch TV or something, because I don't have the inclination tonight to mess any more to try and get my internet sorted, if its something that may resolve itself tomorrow.
Good night from a grumpy kitz.

Sorted -  I also had to reboot my BTmodem & resync before everything went right again.
Whilst a reboot of the TG582n seemed to resolve the speed issues, for some reason the DNS type symptoms didnt clear until I did a full resync of the connection.

Use of address based filtering in the parental settings for certain cause 2 separate issues:-

• DNS like symptoms where web pages are very slow to load or wont load at all unless the page has already been cached.
• Speed throughput limited to 7.01 Mbps downstream & 0.5 Mbps upstream. This equates to throughput for adsl1 after allowing for tcp/ip overheads

A further observation is that opening multiple streams can increase throughput but also implying that something is also wrong with QoS.
 
Analysis of the test performed on 09/11/13 indicated issues with QoS data flow.  The graph provided here shows strong signs of artificial shaping and QoS restrictions.

This is possibly related to the already known issue with QoS.

Quality of Service  Queue-based rate limiting has no impact.

------------
It is highly likely that adsl2+ lines would also suffer the same symptoms, but not quite as obvious as when used on FTTC.
Im therefore moving this thread to the router hardware section as its a problem specific to the TG582n rather than just fibre. 

[kitz]

I still have concerns over this router.

Something I happen to have noticed since carrying out the above tests and have put everything back 'as was', is that although I can achieve 70Mbps+ on speedtesters, this is because they use multi-threading.

If I try to use single threads then my speed is more like 24 Mbps.
You can see on here, what single thread speed is.



Ive tried downloading http files and ftp..  and unless Im using multi-threading then my speeds are vastly reduced.   This is not right!

[kitz]

Is there anyone else on VDSL2 please that can do some testing on this and make sure its not just me thats seeing this, because if this is the case then this router is not fit for vdsl/vdsl2.

Tools that may be useful are

Net Meter.
- Set Options to Graph -> Kilobit for UL/DL speeds.

JDs Speedtester.
- Make sure you turn off multi-threading in Menu -> Configuration -> Download -> Tick box at the bottom of window.

ThinkBroadband Test files.

I'm not sure if this is helpful or may it just raise more questions
This is the TG582n on PlusNet with address based filtering


Using a Netgear DGND3700v2 as a router with same filtering


Results from speedtest.net are 20Mbps/0.7Mbps with TG582n and 48Mbps/15Mbps with Netgear

[kitz]

Oh my 
Thank you for that digbey.   The address based filtering results are 'backwards' to what you'd expect   
It certainly does raise more questions about how the TG582n is handling each thread.

I think I shall give azakka a poke and see if Zen are seeing the same thing.

[digbey]

I'm happy to try out any other tests if you can suggest anything.

How about this other weirdness between the TG582n and the Netgear DGND3700v2 both with fairly light single user.
The Netgear produced similar results on BE ADSL2+

TG582n


DGND3700v2

Quick question: I take it these tests are being run via Ethernet and not via Wireless, also are all these tests being run via the same providers? or different providers?

Kitz, would you (or anyone else for that matter) be willing to use the Zen F/W for the 582N?

Whilst i think of it, the 582N's being used, do these have the Gig Ethe Ports or normal 100mb ports.

[kitz]

@ digbey wonder wth is causing that on the netgear :/ 

It would be interesting is to see what download speeds you get whilst downloading a file from here.

Youd need something like netmeter though to see the throughput.

No matter what I do I cant seem to get much more than 30Mbps (see attached)

[kitz]

@ azzaka

Yes Ethernet. The 582n has the normal 100mb ports and not GigE   

[kitz]

Im currently doing some testing.   This may not be the TG582n afterall. 

I'll post full results when I have them all.

[digbey]

Using Ethernet here also

Using Netmeter

TG582n without address filtering
Down 48Mbps         Up 1.75Mbps

TG582n with address filtering
Down 6Mbps           Up 225Kbps

[kitz]

Thank you very much digbey. 

I think its pretty certain that the address based filtering on the TG582n definitely limits a single connection to adsl1 speeds and multi-threading is needed to achieve anything more :/

This afternoon Ive been doing some further testing with regard to the limitation of circa 28Mbps that Im seeing on vdsl2.
The 30Mbps limitation would not appear to be a restriction of the TG582n nor the Huawei Modem.

Ive opened up a new thread here to discuss this and Im still gathering results.   
So far the 28-30Mb is looking like it may be Plusnet specific :/


 

[Azzaka]

Hey Digby,

I take it you are on PlusNet too? Kitz/Digby is the 582N locked down at all? If not would you be willing to test a different F/W for the Address based filtering?

[digbey]

Hi Azzaka
Yes I'm on PlusNet. I don't normally use the 582n and have no idea if it's locked down but I am happy to have a go to test your F/W if you give me some details.
