우분투 사용시 인터넷이 너무 느려질때가 있다.

 

이때 해결방법임

 

It seems like this is a pretty common problem, and one without a definitive cause. For me, it was because Ubuntu resets the TLP configuration, and the power management went back to "on". I disabled Wi-Fi power management directly by editing:sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Then changed the value from 3 to 2, saved changes and rebooted.

I actually got this solution from Reddit and this worked for my case specifically but it seems like it could be caused by a bunch of other things. Read all the proposed solutions below!

 

<해결책 요약>

① 터미널에서 sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf 입력하고 엔터

② 이때 나오는 아래 스크린샷과 같이 wifi.powersave = 3 을 2로 바꿔주고 저장하면 됨

③ 저장은 ctrl과 O키를 같이 누르면 저장됨. 그 후, ctrl+x키로 나오면, 즉시 인터넷속도가 나아지는 걸 느낄 수 있을 것임
