This is about a strange difficulty with Amazon Prime. Amazon support says they are absolutely not responsible, that Amazon never does this to customers.
My computer internet access is via a mobil hotspot from an Android phone. The phone contract allows only 5Mbps download speed for the hotspot, even though, on the phone itself, download speed may be 50Mbps. Why? That is just what the carrier does.
My Windows 10 professional system (19045.2846) is up to date. Amazon Prime software has recently been reinstalled.
The cell phone carrier started carrying a 4G/5G network a while back. They wanted everyone to switch to the new network but many phones are not compatible with the new network. After being told the old network may be discontinued soon, and being offering a rebate on a new phone, I started on the new network with a new 5G phone three weeks ago. There is no 5G service in my area, so my service is still 4G. The contract for mobil hotspot is the same as on the old network and internet speed tests on the computer still run at the contract speed.
Except for Amazon Prime video downloads:
I’ve used Amazon Prime for the past year by downloading videos on my computer, wuing mobil hotspot of the phone, to watch later because the 5Mbps bandwidth doesn’t always give decent streaming. Downloads were at 5Mbps, according to Windows Task Manager. Now, however, on the new network, new phone, Amazon videos download at a steady 2Mbps, 60% slower than on the old network, and of course it takes considerably more time to download a video. A internet speed test run in the browser, even while a video is downloading at 2Mbps, stills shows the contract 5Mbps download speed (actually about 5.7Mbps).
I’ve gone over this with the carrier a couple of times, I spoke to Amazon Prime support. I tried all their suggestions. I’ve been told by a couple of other Amazon Prime users who agreed to run tests that their download speeds are very fast (they are not using cellphone hotspots). I have run out of ideas to find the source of this problem. It is quite annoying and inconvenient. Any insights or suggestions?
