Cable Modem Help (1 Viewer)

[DeathStar1]

Everything was working fine untill I unplugged the cable modem last week. We have a Motorola 4100 Surfboard, and am using Optimum Online. All the lights are flashing green, including the Activity light, it claims the Ethernet Connection is functioning in the toolbar, at 100.0mb/s . But we're not able to send out ANY email or reach any web pages since it was unplugged.. I didn't change any settings either...

Any help will be appreciated..

Its been out since last week and you haven't called your ISP? Do a release and renew of the IP address.

Are you using a LinkSys Router? There is a known issue with some older LinkSys routers and Optimum Online's DHCP.

Try to renew the DHCP lease through the router, if you get a 0.0.0.0 address returned, then your router may be shot. At that point you can either upgrade the firmware or (sorry to say) get a new router.

If you're not plugged into a Linksys router, the issue is still probably DHCP related. If you're not plugged into any router (shame on you!) then the problem is either with DHCP or DNS on your PC. Can you ping sites by IP address? If you open a command window and type ipconfig what do you see listed as IP Address?
