Youtube buffering at 144p

[pl4sma]

Hi guys. So I have a problem here and I'm hoping some of you know how to fix this. I know this is not a Helping Section but I'll still try my luck if somebody knows how to fix my problem. So I already did all the things I can. I watched and read tutorials on how to fix it I did it all but it's still the same. I already restarted my modem 2 times I restarted my computer. I have a fast internet as well and theres a day which it doesnt buff and can change to any quality I want. But theres some days as well where its really annoying where I can't watch a video anymore because even though it's in 144p it's still buffering way too long. And I can't change the quality as well. Because if I did, it will take longer as well. And this happened to me before but it got fixed just by restarting the modem. But now, even though I do it, it doesn't change :'( Pl0xzcx halp me thankssssssssssss
PS: The buffering only happens in youtube. :'(
