Netflix 4K ports

[#1]

Hi, apologies if this has been posted before, I'm new to the Forum and 4K!

I will make matters more difficult by admitting that I'm a techno idiot so please feel free to talk down to me 😀

I'm connected to a Sony 4K tv via wireless at 32 Mb fibre. Amazon Prime, YouTube 4K and Sony 4K all work fine. Netflix freezes and buffers on 4K. I've now spent 3 hours into Netflix who say it's an ISP fix and Plusnet who say that I need to configure ports but they don't support doing that in the phone and directed me here ....Help please.

One question to which we need the answer - which router are you using

There is another possibility - I don't know about Amazon Prime - but Netfix (according to my Samknows Tests uses 15.6Mb/s) may be trying to use a greater bandwidth than is available when connected via wireless

Hi, thanks for the reply. I am using a Plusnet Hub 1 on a fibre to cabinet basis. Wifi showing about 32mb

Plusnet tech won't offer any help at all. Netflix ditto.

Do you know the upstream bandwidth used?

Can't imagine there being much upstream spare on Plusnets 40/2 package.

About 2mb
