Correct configuration of two routers
In this situation the approach wouldn't apply. He should assign Router B as the primary DHCP server and configure the other as a switch with Wi-Fi features. He aims to utilize the QoS service available on Router B. If he follows this path, he must manage multiple services effectively. Router A should keep its firewall functions active while disabling DHCP, whereas Router B must turn off the firewall and enable DHCP. You mentioned they need to connect via LAN ports and have identical subnets for IPs. In this case, the most straightforward solution would be to convert Router A into a bridge and let Router B handle all network tasks. Based on the OP's current configuration, I assume Wi-Fi isn't an issue, so placing both Wi-Fi modules together would be ideal—even on different channels, it can cause problems.
