Hi Everyone, first time post - please be gentle.


I've been running a Spark HG630 on a 100/20 Fibre plan up here in Albany, Auckland.  This has performed very well and download tests show well into the late 90's mbps on Spark's speed test (through Ethernet).


I have now upgraded the plan to 200/20 and Spark sent me a new HG659b router and duly activated the service.  Just minutes prior to changing to the new router I checked the 630 speed again on the Spark speed test and no problems (was 98mbps), so I simply swapped the routers over (including power supply, but keep the same cable).  However when I speed tested the new router, I achieved approx 65mbps. Swapping the routers back showed an immediate increase back up to 98mbps.


I contacted Spark whom confirmed all their systems showed 200/20 and suspected a faulty router, so they have sent a replacement HG659b, so I completed the swap over again, and have had exactly the same result.


I have not contacted Spark again as yet but I intend to do so, but before I do I just wanted to see whether I was completely missing something really obvious or whether I am somehow the problem?


The PC is near new running Windows 10.  Any ideas or assistance on things to check before I contact Spark again would be most helpful.

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:

Problem resolved - the cable between the router and PC was the issue - it could not handle the load.


Moral of the story - today I learnt to always use the cables supplied!


Many thanks and most grateful to cbrpilot for assistance. Great guy, great advice.

Was it one of those dreaded partially wired ones so you were only getting a 100 meg link to the router?

No it doesn't appear so - for all intents and purposes it looks like a completely normal Ethernet wire. Odd.

Yea, you have to watch those 4 wire supplied cables. Cheap skates.

The wire with capacity issues was a D-Link, probably never designed for 200mbps.  The Spark supplied cables with the modem have solved my problem!
