I think the problem here is local network congestion. Also a protip when somebody posts a small image is to remove the "blog" from the start of the image filename (in the URL) to give you the full image.

ditch the crappy technicolor and try a different modem it may be overheating in the evenings when it is mostly used.

You have a high downstream attenuation of 34.5dB, so your ADSL stats are about as good as you would expect.

 

I've never had an ADSL connection that didn't slow down during peak periods.

This is this mornings test and modem has been on all night. Connections are fairly stable unlike evening times.

is there anything else going on in the evening when you are testing? ie any downloads (streaming torrenting etc) or any uploads (icloud backups or other backups?)

 

it does look like local conjestion.

 

are you rural or urban?

No, nothing else going on.  the same thing happened last year at this time.

 

 

 

I have been told of another Feilding resident who from his property to the Feilding exchange, 1ms. From Feilding to Auckland 2000ms (2 seconds). Off to the USA 8ms. And returned data was about the same. The bottle neck was getting from Feilding to Auckland. In digging around and treating legal action with the Telco, he found out the bottle neck is here in Palmerston North where there was only ONE connection point to Auckland to service Palmerston North, Ashhurst, Feilding and other surrounding areas. As more people log on, the system cannot handle it and throttles everyone's speeds down so that the whole system does not melt down.

 

 

 

I don't know this is a fact but it is what I have been told.

given you are on ADSL2 its likely the cabinet/exchange you are fed from is connected via fibre back through the rest of the chorus/ISP's system and its very unlikely that its going to be congestion on that side of things.

 

have you absolutely ruled out congestion in your own network, and how did you do that? about 80+% of threads on here about congestion turn out to be something in their own network causing the issue

There are only two things on my network. My PC via Ethernet and my wife's cell phone via wireless.  The issue only resurfaced again when the weather got cold and wet so I am thinking it may be online TV and games usage has increased and the local system can not handle it.

like i said its highly unlikely thats the case and you really need to rule out your own network as the cause of the issue

 

can you give us your approximate location so we can see what sort of equipment you are connected to

ps it doesnt matter if you have 2 or 20 devices on your network, they can still cause congestion so you really need to rule those out

Palmerston North will be the Ethernet Aggregation Point for the whole region but any such talk of the "system cannot handle it" is really just compete rubbish. RSP's have a choice of buying their own backhaul or using Chorus tail services for transit, so any claims there is one connection point is simply not correct.

 

Those ms figures are also incorrect - it's around 130ms RTT to the West Coast of the USA from Auckland. 1ms to the cabinet/exchange is only possible on VDSL2 with DLM-1 and not on ADSL2+ or VDSL2 with any other profile.

 

At the end of the day you're seeing a ~20% drop during peak time. Many people would argue that this is perfectly reasonable, and if you look at the Truenet results you'll see that isn't abnormal normal for many RSP's. If you have totally ruled out upstream saturation as causing a slowdown in downstream it looks like your RSP is simply suffering (very minor) congestion on backhaul out of that region. Your best option is to find another provider if you're wanting to get better speeds, remembering that expecting to see linespeed 24/7 is an unrealistic expectation. You might see you peak time increase by another 1Mbps or so which at the end of the day is highly unlikely to deliver any measurable difference in performance as your latency doesn't seem to be affected by the possible congestion.

Thank you.  The terminology you use is lost on me but i get the drift. You think the evening losses are OK.

 

 

 

What happened to "Speeds as fast as your line will allow"?  My line allows over 11Mbs

it doesnt say all the time though does it :) if you looks in the terms and conditions im sure you will find a clause that says they cant guarantee it 24/7
