Hi, on EU version we have the same problem with packet loss and latency - can you update the EU firmware also? Another thing - 5GHz network is disconnecting from time to time - doesn't matter if it's the iPhone or PC. Please fix that also. I'm running the latest firmware (1.3.6 Build 20200902 rel.65591(4555)) available for this router (Archer C6 v2.0)

You may update to the beta firmware we posted here first, then monitor if it helps resolve the issue:

They are unable to fix 5 GHz. They have asked me to downgrade to 1.2.x.

I first downgraded to 1.3.6 20200907 rel.60850(4555) since this was working well for me apart from synthetic packet loss issues, which however did not affect normal functioning of the device. However I noted a new issue with this. In my topology, when I move from f0 to r0 on 5 GHz wifi, feeds fail to load. Suspecting some kind of handoff problem, I disconnected the wifi on my client device and reconnected. However, images and videos still failed to load. Again, this is present only on the 5GHz network and not on the 2.4 GHz network. I have tested with multiple client devices and all have this problem. It only resolves after a couple of minutes being connected to the 5 GHz of r0.

 

Then I downgraded to 1.2.1 via a method from your engineers. This 5 GHz roaming problem still persists. I have yet to check packet loss problems. 

 

This roaming problem also exists with 1.3.6 Build 20201030 rel.60104(4555).

Upgraded to 1.3.6 Build 20201208 rel.52296(4555). 5 GHz loading problems have gone away.

 

The roaming problem remains, both on 2.4GHz and 5GHz. I have more specific info on this. Roaming between the access points F0 and F1 is seamless. When roaming from the access points to the router R0, I get connectivity problems with content failing to load.Roaming from R0 to F0 or F1 is fine. I am not the only one experiencing this it seems:
