Yes, that was the first thing Meraki support thought we missed. The maximum value allowed is 500M on our model. With the slider or manually type in, it limits to 500 and that's how we have it set. Along the way, I had set this down to 10 and saw it limit to 10 both up and down, then moved it back to 500 and the download moved to 500 as expected, but upload only rose to 100. I also tried a few silly things like a download limit of 1 with an upload of 10, 50, 100, and 500. Everything functioned as expected except upload topped out at 100 regardless of how high I went on the config. Personally, this is what I think may be 'corrupt'. While the slider shows it changing, internally, something in the config still has the upload side set to 100M and it won't update. Why it would slow down, but not increase, is a mystery, but I've seen stranger things happen in code. Nothing else I can think of would limit upload only.
