Hello Judith! Thank you for your question. I am a licensed network professional with over ten years of experience, and I will be assisting you today.I'm sorry about the issue. What's the model of your router?Do you know how to log in the router?Have you tried to update the router's firmware, if any? And/or have you tried to reset the router?If there is a modem, have you tested if the modem is working fine (i.e., disconnect the router, and connect the computer straight to the modem, then see if internet works fine with the modem only.)When you are available, please click on the Reply to Expert tab below, and reply back to me, so we can continue. Thank you.
