Internet Router Modem

Hi Everyone! I'll get right to it. My internet stopped working suddenly. Here are the symptoms, it seems like whenever I connect my Modem to my router then to my computer, it can't get any internet but when I connect my modem directly to my computer. I am able to access the internet, and that's...

I recently upgraded to win10, and scroll hasnt been working since. I have tried downloading smartgesture from their site but I think its not for this laptop since it has two physical left and right buttons (thats what they said on their site).
