Not sure how fast you need it to be.
Unless actually downloading a large file ( which I have done on occasion, in the gigabyte's tethered ) then it's probably a bit over kill for streaming etc.
My TV provider states that anything over 10meg is acceptable for streaming HD. Which circa 5 years ago was all we had here via ads and it worked fine.
Back to op, I am curious also. Will run a few tests in same location as my S8 / S7 / Op3t Etc
