Hello Community , 

I observed that my Internet Speed has dropped and when I logged in to the Router , everything seemed normal.

Upon checking the Network Shelf, I noticed a LOS Light on one of my ISP Router . Internet was down. ( It  was actually down since a couple of days ) which was cause of my slowness as it was running on only one link. 

The Question is why does the ER605 does not detect it as down . I am sure if I reboot it , it will show it as down . 

But , why this. Is there a setting I am missing ?
