You didn't say what your normal bandwidth is and I don't know how you determined the numbers in your photo. Anyway, here is the procedure to use with qos.
If you are running DSL with 3mb or less, you could have a qos problem depending on how much bandwidth your other computers are using. The qos is set in the router. The first thing to do is assign a fixed address to the obi. Then run a bandwidth test without any other activity using bandwidth. The upload and download speeds will be used to put into the routers qos tab.
By doing this, the router will give priority to the Obi.
