[help] increase wi-fi signal with a repeater

[GHL]

Hi all, good day,

I would like to know if there is any wi-fi repeater able to repeat the signal with high data quality because the standards repeaters doesn't work in some situations.

I have a standard repeater that is sufficient to increase connectivity for browsing on the social networks, for example. But when i need to play a stream in high quality or my son tries to play online in his video game i note a lot of lost packages, so i can't see advantage for use a standard wi-fi repeater in these cases.

What can i do in this situations? Could you help me?

Tks!
