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.
