Anurag, I have exactly this set-up, also with an ubnt edge router. I have two probes connected #7 & #8: https://atlas.ripe.net/probes/7/ https://atlas.ripe.net/probes/8/ I route the probes explicitly to each uplink independently of which uplink gets used by most of the household. Personally I would suggest for you to choose one uplink and measure that like you are doing now. If you feel adventurous, get another probe and configure like I do. I would advise against measuring a combination of two uplinks. It will produce confusing data, especially if the uplinks are via two different ASes. Daniel
