It is not clear if the Huawei HG8045H has Gigabit networking ports or not. The broadband speed isn’t an issue since your having problems across the local network. Only for remote access would broadband speed be a factor. If you do not have Gigabit networking ports on the Huawei HG8045H then the speed (copying data) will be slower. One can run benchmarking programs (like CrystalDiskMark - http://crystalmark.info/?lang=en) to get the general transfer speed between your computer and the My Cloud when copying data. There are many factors including the speed of the network, speed of the hard drive, and other issues that can affect copying speeds across a local network connection.
There is some discussion on copy speeds in the following thread:
If you have not updated the firmware for your My Cloud to the latest version you may want to do so. Particularly if you use the older v4.x firmware on the first generation single disk/single bay My Cloud. The latest v4.x firmware seems to load the Dashboard slightly faster. Otherwise the Dashboard has always been a bit slow in loading or updating the information on the Dashboard page. You can use the search feature, magnifying glass icon upper right, to search for other discussions on the slow loading Dashboard issue.
