Hi @soufianez318, I immediately checked your connection and it doesn't appear to be disrupted currently. It it just the Wifi that seems to fail to connect, or does your wired ethernet-connection falter as well? Which repeater/access point are you using? It seems to disrupt the line. No worries though, nothing that can't be fixed! 
Check which lights are on on the modem. Does WAN or Internet not light up? Then disconnect the modem from the power for 10 seconds by unplugging the power cord. - Is it about Internet and is the WLAN light not on? Then press the button "WLAN / WPS / Wireless / wifi" until the light comes on. - Are the lights on, but you are not connected? Then connect your computer directly to the modem with an internet cable on port 1 or 2 of the modem. If you have a Zyxel modem, it doesn't matter which port you connect the computer to. Does it still not work after this? Then follow this link: https://thuisservice.t-mobile.nl/internet-en-email/wel-wifi-geen-internet. This allows you to solve common problems. Hope this helps!
