The last few nights here in ChCh my speeds have plummeted in the evenings. Usually I get 38Mbps. At 7.15 tonight speed has dropped to 19Mbps.
Last night at 9pm it was below 7Mbps. I have lodged a complaint and so far I've had a reply asking the usual things...are you testing over wifi etc.
Testing speeds over ethernet via Spark website. I've been taking screenshots...provided Spark with one at 38 and the other at 6.
I know about the "Netflix effect" supposedly affecting most ISPs but is anyone else being affected this badly?
Not a happy camper!!! :(

Just now at 7.30pm as I finish typing this it's 17Mbps.

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

 



 

If you are posting regarding DSL speeds please check that

 



 

- you have reset your modem and router

 


 

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

 

- you are not being throttled by your ISP due to going over the monthly cap

 


 

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

 


 

- you read this topic and follow the instructions there.

 



 

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

 



 

- Your ISP and plan

 


 

- Type of connection (ADSL, ADSL2, VDSL)

 


 

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

 


 

- Your general location (or street)

 


 

- If you are rural or urban

 


 

- If you know your connection is to an exchange, cabinet or conklin

 


 

- If your connection is to a ULL or wholesale service

 


 

- If you have done an isolation test as per the link above

 



 

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

 



 

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

 



 

I recommend you read these two blog posts:

 



 

- Is your premises phone wiring impacting your broadband performance? (very technical)

 


 

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?




I am the Geekzone Robot and I am here to help. I am from the Internet. I do not interact. Do not expect other replies from me.

Please answer PeterReader's questions.

Your problem sounds like congestion in your actual network likely caused by somebody downloading.

Is anyone else in Christchurch experiencing a similar issue?

Spark VDSL unlimited. Urban .

Bandwidth (Up/Down) [kbps/kbps]: 10,354 / 40,460

Line Attenuation (Up/Down) [dB]: 13.8 / 6.5

SN Margin (Up/Down) [dB]: 28.3 / 12.2

I've had a couple of replies from Spark this evening basically asking for a few more details.

At least they answered this time. Still waiting on a reply to a query from last week.

Now below 7Mbps at 9pm.

What is on your network at the time of testing? What services are running on your computer? Do you have Hola installed on any computers? Have you tried on another computer on Ethernet to ensure it is not your computer?

Nothing new on my computer and nothing connected that should cause this. Just my wife and I here during the days that this has been happening. Not using any streaming services.
It returns to normal after "peak hours".
Spark has asked for 3 days of test results for download speed and pings, morning, afternoon and evening.

Same thing happening to me. Used to have real good speeds on VDSL. Check these speeds from yesterday (today is just as bad), as you can see it starts dropping very quickly in the evenings and NO nothing has changed in my house except I changed plan to "unlimited" a few days ago. Unfortunately I can't provide speed test prior to that. Anyway have also contacted Spark and got the "we will have a techy look at your line, give it two to three working days". Tomorrow is deadline and you can bet I will be on the phone if I am not contacted by tomorrow evening, Paying for VDSL speeds and not getting it is freaking annoying.

I get the same in the evenings and am in chch. This is a test done just now.

I am on a wired connection and vdsl , During the day I get 50-60 mb/s but after 6pm it plummets. I guess its congestion.

Sounds like you need some sort of SLA managed service if you're relying on your connection for work purposes.

I added in my latest reply to support a link to this thread to show it's not an isolated incident.

WJAM where abouts are you? I see Presso is in ChCh like me.
