I've been struggling to understand how my Fibre100 plan has dropped to Fibre30 speeds. I called SPARK support to investigate. I was told my plan was Fibre100 and hadn't changed (incidently I've never had another plan speed). We then ran through a few test options


Current connection is through a Linksys WRT1900AC. It's connected directly to the ONT. I ran the router's ookla speedtest (included util), and ran one (spark one) from the PC connected via ethernet to the WRT1900AC - both consistently produce download results under 30Mbps. Media prioritisation is turned off, so no router shaping.


I've restarted the ONT and router, with no improvement.


SPARK support suggested that it was a Chorus issue, but also advised the following: "Chorus will probably say it's your problem because you're not using the SPARK provided router." It's been a week since the call, and neither SPARK nor CHORUS have responded. Should I keep pestering? Is there anything I can try other than what I have already done?

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:

Do you have the spark provided router to plug in and test?

It's been well over a year since I've had Fibre installed. I think I replaced the router a few times since then. I doubt I'd be able to find it. I might be able to locate one at work - we have a few sitting in boxes somewhere untouched.

Plug your computer into the ONT directly.


Set VLAN 10 on your network card and start a PPPoE dialer.


Run another speedtest.


This will rule out any router issues. (It's surprisingly common how many so called "fibre speed issues" are caused by the router.)
