In Jomtien, stuck with TOT. Previously, I had 1GB down and everything ran great, but expensive.  This year I tried downgrading my speed to 300mps, less than half the price.  At first OK but now I notice many HD YouTube videos do not play smoothly, kind of jumping.  4K Netflix TV also very uneven with some buffering.

I did several speed tests and am getting about 360mps up/down so I am getting what I'm paying for.  Would upgrading to 500mps likely solve my playback issues or do I probably need to bite the bullet and go back to 1gb.?

BTW, I live alone so not sharing the signal with others.

I read that 25Mb/s is OK for 4K, and much less, 3Mb/s, for Full HD.

Bandwidth by theory is much more than needed (post above).

As you say you did a speedtest to ToT and values are OK.

Now it's about connections to overseas that can be much different.

 

Popular youtube content is mirrored by Google somewhere in the region (Singapore, Hong Kong, Thailand?) and should never make problems.

But where does Netflix come from? I don't know.

 

You connect via cable?

What device? PC?

 

Call the Hotline and complain. You don't need many Mbps to play videos. Here what Netflix says

Try another speed test; https://testmy.net/

 

Even a 30 Mbps connection should be enough. Maybe the 300 Mbps is just for domestic traffic. 
 

Use the speed test above and vary the test servers. https://testmy.net/mirror

if you pay less because you think you can get same service, you're wrong.

lower tier packages could have higher contention ratio (bandwidth shared with more users).

Thanks for the reply's.  I'm a bit embarrassed to say the issue turned out not to be my internet service but the position of the router in my apartment.  Even though it looked to be central, for some arcane reason, the signal apparently had a null at my TV location.  I tried moving the router 6 feet and everything improved immediately.

My W11 connected to 3BB by CAT6 cable.

testmy net 137/123 Mb/s (London)    194/67 (Singapore)   

Speedtest      948/498 Mb/s (3BB)

That's why I asked WiFi or cable

In my room PC and notebook on cable with gigabit switch.

WiFi is for gadgets (mobiles and tablets).

Quite the difference, though still eminently usable. 

I was going to say 300 MBPS is more than enough for Netflix, even on an 8K TV, so the problem lies elsewhere, which the OP confirmed.
