I've recently performed a firmware update on my AX6000 router and the download speed dropped to a 3rd than it should be.

My subscription with the ISP Provider: Upload 40MB/s Download 600MB/s.

And this was also what the speed test on the router was showing until recently.

However two week I've done two things: bought an RE200 extender and activated OneMesh.

At the same time, I've was asked to update the firmware and I did.

Now, one of this actions affected the download speed:

I've tried disabling OneMesh - but same result.

That's why I'm thinking it may have to do with the firmware update.

I've checked with my ISP and I should still have 40up/600dwn speed.

I've also read the forum and checked:

- QoS - set to Standard

- No antivirus

- Link Aggreagation  - disabled
