Configuration: there, you better have the light and know the ins and outs of ideas, its just not recommended for novices. Nothing worked, and after three hours it is in a forum I found the reason for the problem.
The rate will not change: Your video will not load faster, loading will be through a WAN connection, a single, not all available WAN.
However, if another application wants to load a video simultaneously, then this new application will go through another port and then it's effective.
That increases the bandwidth for ** all ** but for a given loading, nothing changes.
If you disconnect a WAN access, queries pass through the WAN access or remaining available, the reliability is there: it was my problem and it is fixed!
