I learned it the hard way…
I have two WANs, Starlink and Verizon Home Internet
the Verizon Home internet has a very consistent up/down speeds (it is throttled, yet they allow a short burst at the start of a connection)
the Starlink speeds are all over the place, from as low 20-30 down to as high as 500mbps down, but the average is about 60-80mbps
so, I thought that I should enter 60 as the download speed for Starlink, so that the various algorithms that use up/down bandwidth will do their thing based on the avg speed that I entered
what I did not expect was for the Peplink router to cap the bandwidth to the values that I entered and never exceed them!
so now, I have 500/50 for the Starlink and 100/20 for Verizon to allow for the initial burst.
but this means that the algorithm that would use these values will not longer be accurate in making the decision as to which WAN to use.
for example, “least used”, will always choose Starlink since Starlink at 500/50 will always have lots and lots of “theoretical” capacity left, even though in reality, it can only average 80-100/10-15
I really wish that there was an “automatic” way for the algorithms to figure out the available capacity for each WAN
