I've noticed a speed drop in downloads.

This chart shows testing to the 2degrees Christchurch speed test server from my Wellington fibre connection (900/500):

This is tested from a NAS connected via Ethernet to the router.

I tested again at 11:43 AM (as per chart). Nothing much else going on at the moment:

I have tested from my desktop to the same server and different servers with different providers. The results are consistent with a 50% drop in speed.

I have restarted both the router and switch.

This is still ongoing on Saturday at the time of this post. Is anyone else seeing this?

The 300Mbps plan is working ok. I have noticed some latency opening websites the past few days, but that could be something on my network or something about my computer.

No, but I will try it after the half hour - I have a job that runs before that.

FWIW, given your result to speed.snap.net.nz I tried from Spark, and the latency and packet loss seems a bit high...

I found a DNS problem in my network causing the issue, so it's all working fine for me.

Problem solved. Stay on, it's a ride.

The problem was identified around Friday at 4:30 PM.

I tested a lot of stuff on my side, including removing the switch (I've seen a packet storm before), the NAS, and everything else. I plugged my PC directly into the router and the problem persisted.

At the same time, I was due to move to Quic. So while I did not see anything from other users I thought why not? So I put in a port request on Saturday 4:20 PM and the connection was moved from 2degrees to Quic at 6 PM. That was fast!

The problem persisted, so this was evidence it was on my network.

I plugged my PC directly into the ONT and the speeds were as expected.

I replaced all cables, and I was about to factory reset the router and restore a configuration backup when I looked at... Traffic Control.

Some time ago I decided to try Traffic Control to see if anything would be impacted. Nothing good came out of that.

The only device in the Priority group was the Panasonic TV. Around that time I swapped the old Panasonic for the new Panasonic 2024 for review.

And I turned Traffic Control off. Or so I thought.

Panasonic advised me they're sending a new model sometime, so I'm sending the 2024 model back. I put my old Panasonic back until the new one arrives.

When my old TV connected to the network the router turned Traffic Control on again (or I never turned it off really).

It doesn't matter. The speed slowdown coincides with the time of the TV swap.

Anyway. Problem solved now.

Thanks to anyone who replied or looked into it.
