Dashboard very slow

Hello, I have a model ex4100. My dashboard is very slow, I am not able to connect. The browser stops the connection to the dashboard. Do you have an idea? What can I do?

@fblaquiere First you say the Dashboard is slow then you say you are not able to connect, connect to what, after that you say the browser stops the connection to the dashboard.

Does the dashboard open or not?

I have two WD My Clouds, a 1st generation and a second generation. It takes longer for the dashboard to show up from the 1st generation than the second, however they both eventually show everything.
