Hello,
I have Merlin AC86U as router and AC68U as AiMesh node, does anyone notice that sometimes the AiMesh node: 1 change 0 and then 1 ,,,,,I watched it like 5 mins ago, it did go to 0 and back to 1 very quick.

Additionally, does anyone have issue on Internet Traffic on the System status page stopped reporting...it's just shown --KB/s for Down & Up

Both my AC86U & AC68U have latest Merlin 384.17

Regards,
