Hi, I'm a newbie to the Deco system, but managed to set all three nodes up no problem.

Where I live I have a limited internet with only one option- Wireless system Domestic Broadband - 8Mbs Download/ 1 Mbs upload

This is generally sufficient. I set up my three pack of Deco M5 throughout my house.

Main Deco in living room connected to main internet cable ( a dual ethernet/ powered cable directly from the dish) and the two satellite Deco's -one in bedroom, one in office (in bungalow) - signal source - 2 bars on each.

All seemed to work fine - I could hook up to the internet throughout the house.

However, I noticed all three Deco's indicator lights intermittently going from green to red - for only a second or two - but constantly every 30 seconds or so. And the internet signal would drop out entirely for maybe 10 seconds - enough for my Google home mini to stop streaming music.

I looked through the forum and decided to test the internet by connecting it directly to a computer and doing a Speed Test to see what was coming into the house from my internet provider - the results were consistent enough Download 8Mbps / Upload -1Mbps. I repeated the test and it was pretty consistent. See two tests in a row:

But when I connected the internet cable back into the Main Deco, then using a second ethernet cable to the same computer the Speedtest via the Main Deco varied wildly. Sometimes the Download speed was correct, but moments later it could drop away completely and sometimes the upload would be fine but the download gone and vice versa.

I also did ethernet tests on the other two Deco's directly into the same computer

The Office one also jumped over the course of half an hour like this:

Download/ Upload

8.37/ 0.65

3.64/ 0.00

1.67/ 0.89

Bedroom:

7.40/1.36

3.14/0.00

6.49/1.03

So my problem is that the internet once it's going through the Deco system seems to keep jumping up and down and cutting in and out. Any suggestions welcome.
