I am on 50/10 with TPG last game I installed on the xbone the other day wasn't that bad not as quick as steam but it wasn't horrible. Steam flies along did a 20gig patch the other day in 55 minutes and thats running a cable from a wifi range extender to the pc.what do you usually get when downloading / updating a game?
My internet plan is 25/5, on the opticomm fibre and if i do a wifi test on my phone or a speed test on my laptop im usually hitting 20's or higher with ease.
but it is only ever on the PSN and even XBOX console download speeds are extremley low and i dont know if i can fix it.
Have you tried running a cable to the console and see if your wifi is the problem?
