    I dont think Presenter is a good place. Presenter should ask the new data from the model, like getData(). Presenter should not know whether its from local database or from server. So checking the internet connection at the Presenter will not be a good idea.

    If you use the Repository pattern, the Presenter will ask the model/repository to get the data. The model will send the local data to the presenter first. Parallely, it will send server request(if there is network connection) to download new data, and send the new data to the Presenter.

    So I think, the network check must be at the Repository/ model. You could have Util class which implements the actual network check code. And call that method from repository, like AppUtil.isNetworkConnectionAvailable();
