I left origin on overnight and slept 7 hours, only 1 gigabyte installed. When there was no traffic on my WiFi earlier I got 8 gigabytes in an hour. Is there a reason for this?
This would point to an issue with your connection, if you are seeing slow down in speeds as you are the best thing to do is start by power cycling your router which you can do by unplugging it for a couple of minutes and then turning back on.
