Hmm, your cable modem is trying to broadcast DHCP packets for your ASUS laptop. And the packets seem kinda malformed, but I guess acceptable.
Unplug your ethernet cable, unplug your cable modem. Plug in your cable modem, plug in the ethernet jack.
How long did you have this combo working before it took a dump on you? And can you access
http://192.168.100.1/ from your laptop when it is on the internet?
