Hi,

I have confirmed with the engineers before that as long as the CPU is back to normal after the refresh, it would not cause any further issues.

Since the CPU load on the web UI is not real-time updated, it will show up as 100% sometimes.

So now we need to focus more on the unstable bandwidth, may I know the dropping range of the bandwidth, like from 100m/s to 10 even 0m/s?

How many times would it repeat within one day?

If not rebooting the Deco, would the speed remain slow?

Thank you very much.

It's happened a few times recently. I actually test the broadband speed hourly (I had some previous problems with the ISP) - see attached logs from the last couple of days (Date, time, Down Speed, Up Speed, Latency)

The drops in speed are definitely related to the Deco wifi as I have a 'Sam Knows' device that confirms this 

Rebooting ALL the Decos seems to help for a while

@TP-Link 

It happened again today - logs attached again.. I'm actually no longer sure if it's related to the CPU load as it's now showing 90% CPU but still slow network speeds.. Is there any other data I can send you? Also - do you want to move to another thread as it may be unrelated to the OP?

thanks
