Getting on the internet take 15 minutes when using windows 7 and explorer 11, is there a fix?

I'm guessing from the mention of a Samsung Galaxy cell that you're using your phone's mobile hotspot to provide internet access to a notebook or other PC with Windows. If this is incorrect, please provide additional info as to how you're getting internet access.

A number of things can cause slow internet speeds. 1) distance between you and the cell tower, 2) Data technology 3G, 4G etc., 3) method of connection between your cell phone and PC - obviously a direct connection via USB would be best, but a WiFi or BT should do well enough - if - close by, 4) multiple hotspots in close proximity cany make it impossible for your phone to create a hotspot on a clear channel. Experiment a bit and if still no luck, provided more details about your connection.
