How do I adjust a WAN set limit of 1.5Mbps?

#1

On my Roku 3 I encounter poor playback fairly regularly. When I look at "Playback" settings of each file I see a "Limited Quality" indicator. On clicking this I get message "Connection is on WAN and limit is set". Quality of files is often double the limit of 1.5Mbps. How do I adjust please?
Thanks

could be Settings > Server > Remote Access > Upload Speed or a setting in your client (there's usually a playback quality option for home network, internet and mobile access).
