@Pendidikan Khusus Profesi Advokat @deepakkathayat1997 I had similar problems but found it was Windows 10 causing issues. Steps I took to resolve issues.
1, Goto Device manager, network adapters, select your wifi adaptor, power management, UNCHECK the box 'Allow the computer to turn off this device to save power'. Keep a look out with further windows 10 updates as sometimes it goes back to this setting after big updates. Just go in and uncheck the box again.
2, In Update & security, turn off delivery optimisation from other computers. Switch off running background apps or reduce number of apps running.
3, Follow this link to remove bandwidth constraints. This increased my internet response speed by approx 30%
