I would like to suggest a "Live ISP Traffic Throughput" by having an option to change the default 5 min refresh rate to actual real-time traffic of individual WANs.

I have a dual-ISP setup on my ER605 v2 router with optimized application connection setting enabled. I noticed that the overall throughput of all wired connected devices (downloading & uploading files) don't fully utilize the bandwidth of both ISPs. I have 500Mbps and 300Mbps ISPs, also set the load balancing to 5:3. I should be getting near 800mbps bandwidth for all the connected users but i only get right about 350Mbps total (at this rate i could've just used ISP1 !)

Having to see realtime WAN traffic can help me see if I had set up everything properly and to see the current user who downloads in real-time.
