Archer C6 2.4GHz latency, packet loss problems

Hello everyone!
This is my first time testing network equipment. My home network layout is as shown below:
Did not check what firmware the Archers came with. Updated all to 1.3.4 due to the 2.4Ghz channel being stuck on 5. On 1.3.4, when all 3 2.4Ghz networks were online (with guest networks also online), I could induce packet losses and latency spikes for all devices connected to the network by loading the network using 1 device – just browsing through a news feed or social media from my phone really fast. The devices use the same SSID and password. From the monitoring device, it looked like this:
Wifi signals at the monitoring device looked like:
Disabling one of the networks resulted in a reduction of packet losses and latency spikes, but they were still present (here r0 and f0 are active, f1 disabled):
Just running 1 network, packet losses and latency problems were reduced further, but didn’t go away (only r0 active):
So I upgraded firmware for all three to 1.3.5. Stability improved dramatically and packet losses and latency spikes have gone down with the three networks active. However, if I go to the edge of the network and load it, there are spikes in packet losses and latency:
This is not normal behaviour right? How do I fix this? The devices are all brand new and still under warranty.
I take a phone and a laptop (loading devices) to a place where the signal strength is low.
Signal at my phone:
Signal at my laptop:
The monitoring device is at a location close to the router where the signal looks like:
Now when I load the network from the loading devices - play videos, browse feeds, I get packet losses in the connection between the monitoring device and the router:
This is not normal behaviour right? I expect low speeds at the loading devices but packet looses across the network are not supposed to happen right?
This is not completely limited to the low signal regions, happens occasionally well within the network.
