My Archer C5w v4 when Enabled Bandwidth Control, limits Wan speed to 100MB, even adding 512000 (which measures in Kbps) in the Up and Down field, as it handles a Gb interface router, creating a firmware error, how to solve?

No help fields that can assign values up to 1000000, but unfortunately still report the value and limit to Wan at 100MB.

Note: I did not find the correct model for selection, so informed at the beginning of the problem.
