I’m on an 80 Mbps symmetrical fiber plan. My AX12 is connected to the AX53 via LAN and set to AP mode, with QoS enabled, and it consistently shows ~6 ms ping on Wi-Fi. However, when testing directly on the AX53 main router’s Wi-Fi, the download loaded ping is noticeably higher, even though speeds are similar. Tests were done on an iPad Pro M4using the Speedtest app. The AX53 is currently running beta firmware, which may be causing higher latency due to extra processing (QoS/NAT/Wi-Fi scheduling), while the AX12 in AP mode handles Wi-Fi only and therefore shows lower and more stable ping . Just see the down/load high and low ping the upload is okay the first test is of ax 53 and the second test is of ax 12 in ap mode
