Have to restart my computer to connect to internet Windows8

I just bought a brand new Dell Desktop and it worked great for about 1 week with no issues; now everytime I try to connect to the internet I have to reboot my modem and computer. I am using Windows 8 and wondering if maybe the modem (from Verizon) needs new driver updates for Windows 8...does this sound right? If not can someone help me troubleshoot this please.

Thanks
