Model: Deco S4

Hardware Version: V2

Firmware Version: 1.5.1

I received the new hardware (3 pack) and installed this yesterday. Everything working fine. Very fast wifi connectivity.

However, I'm facing a strange behaviour where if I try to run a speed test on speedtest.net. My internet connections completely drop off.

To fix the issue, I have to unplug the ethernet port from the main deco point. Then plugging it back in after a few seconds.

This happens if I test this on speedtest.net website via laptop or speedtest.net app on mobile.

I've checked and confirm the wifi points are on the latest firmware.

If anyone can shed some light on the issue and resolution that would be great.

@Emsee

Hi, welcome to the community.

Did the whole internet service on Deco S4 get interrupted? or just on the laptop and mobile phones?

Have you seen the main Deco turn red during the speedtest?

Please try to change the WAN DNS server on Deco to 8.8.8.8/8.8.4.4 to see whether it helped or not:

And may I know your internet service provider and if possible, could you please help me run a simple test:

1. temporarily unplug Deco from the ISP modem and connect a wired laptop via Ethernet Cable to the modem directly.

2. run a speed test via speedtest.net or APP again to see whether the PC would be disconnected.

Thank you very much.

Wait for your reply.

@David-TP any further feedback? I have the same issue, speed test through router and direct works well.
