I bought a new phone (Huawei P9 Lite) some weeks ago and changed my phone provider. When I try to share its internet to my laptop via ethernet hotspot, the speed of the connection is quite slow.
I used to have a Nokia Lumia 925 and the internet would go quite well. For example I could play online videogames with around 60-70 ms. Now sharing the new phone's connection I can browse and stuff, but if I try to play an online game I have more than 100 ms and I noticed that sometimes the connection drops.

Do you guys think it's a problem of the phone provider (which means I can't do much about it..) or do you have any suggestion on how to solve it?

Thank you!
