I'm planning to add a RPI4 to my network configuration for better performance with SQM/QOS. Before I do so I want to be sure my current configuration is correct. So I have 3 Archer C7's.
I'v read a lot on this forum the last month about trunking. Everything is working well, except onder heavy load. For example when one client is download wat 250mbit. Even with SQM disabled, the network isn't stable anymore. So I want to be sure if I configured the switch and interface correct.
Below a schematic presentation of my network.
Right now I don't have the possibility to add more cables. So this is the situation.
Below screenshots of the switch configuration (luci):
So my question is, did I configure the trunk correct? Or did I create a loop somewhere which decrease the performance?
