SOURCE: New modem will not work with my Belkin F5D7230-4 router

I would start by re-setting the modem. Disconnect the power for the router and modem. Wait a minute or two. Plug the modem back in first. Wait for the modem to complete communication with your internet service provider. When all communication lights are good on the modem then plug the power into the router. It amy take a few minutes to get all the lights. Hopefully this will allow the DHCP to release from the old router and renew to the new one. Make sure if your internet provider requires any manual configurations that they are properly configured in the new router.

SOURCE: cable modem + dlink router

Your modem needs to be rebooted in order for your router to pull an IP from the modem. To do this, look for a little hole in the back of your modem and use a pen to push the button. Wait for the reboot to finish and then try again in about 20 seconds.

SOURCE: Switched to cable(arris modem) can't set up network

cable dsl same thing. Did you switch providers and get new modem from them? If so. Just delete previous netowrk and install new one let pc discover new one. Also, with your router you got a disc. It should install correctly. Perhaps it is previous network that is hindering you.

SOURCE: ARRIS Modem + D-Link router = no internet

when you are on Cable Internet with a "modem" only connected directly to the computer, what the ISP see is the computer's MAC Address (command prompt -> type ipconfig and hit enter).

put a router (which has it's own MAC Address) in-between and the ISP wont let you cause it sees the router not the computer.

check physical connection: cable modem -> router -> computer(hard wire for this troubleshooting)

access the d-link gui and locate the “Clone MAC Address" button (supposed to clone the computers MAC Address - verify if it's the same), save settings & reboot the router.

How do I find the bridge mode in sb6121


The Motorola Surfboard SB6121 is a cable modem only - no router included.

You must have a router - after the modem - in the network if you need router duties.

There is no bridge mode in the modem. Bridging the modem basically bypasses the routing function of the device and passes everything on to the next device in line......the router in this case.

Since this modem does not have a router built in - it is always in bridge mode.

FLASHING AMBER LINK IDICATOR LIGHT ON MY SB6121 MODEM


The SB6121 link light uses color to indicate the connection speed. Blinking means data transfer is taking place. Blue means that it's a 1000Base-T (High-speed Gigabit Ethernet). Amber means it's an older ethernet device. 100Base-T or 10Base-T Ethernet connection.

And orange bliking light came on what does it mean


If your belkin wireless router is flashing orange, it more than likely means it was hit by a power surge or got wet and popped the circuit on the mother board of the router. Took mine apart and found where the circuit had been blackened by power surge hitting it. I was able to salvage one important thing was the antenna that can be adapted to other systems if you know what your doing.
