Download lento com Upload veloz

Olá.

Foi instalado recentemente uma internet de fibra ótica em minha residência, quando fui
testá-la (no Celular), o Download ficou em torno 20/25 Megabit/s, já no
Desktop, a velocidade de Download é aproximadamente 8 Megabit/s e o upload em torno de 23 Megabits/s.

Alguém poderia me dizer o porquê deste incidente?

Obs: Testei todos os adaptadores e entradas usb disponíveis, todos tiveram o mesmo resultado.
