I have googling around to find if there anyone have problem like mine.. my problem is strange and i never experience before. I have call streamyx about 5 times try to solve but no solutions till now.

The problem is i can't connect during day time.. but everything just back to normal at night. It like have been setup. Everyday my streamyx will disconnected around 10am and back connected around 7pm. Technician from streamyx have call me and said it such a strange problem.. anyone facing problem just like mine? please share if there any solutions for my problem..
for sure not my modem problem or desktop because i have tried two  different modem that worked and different desktop with different OS..
