SOURCE: Ethernet Port failure new router

Check the socket in either the router or the PC. I had the same problem, only with my modem. When I inspected the port, the pins were misaligned, causing it to drop a connection. I corrected mine with a screwdriver, which is not ideal but it works.

Make sure that you have the ethernet cord from your modem plugged into the WAN/Internet port on your router. Then unplug the power cord from your cable modem and plug it right back in. After the modem fully comes back online, unplug the power cord on the wireless router and plug it back in. wait 30 - 60 sec and then try and connect.

Most cable companies only allow one active"CPE" at a time for internet access. All this means is when you change what is connected to the cable modem you must always reboot the cable modem to allow access.


Hope this helps. Let me know if it does not work.

Please rate.

SOURCE: Cannot set up Motorola Surfboard SB5120 modem

This usually means something is not correct with your incoming signal. If your cable wire into the modem is being run off an amplifier in the wall this could be effecting your service. If the signal is too strong the modem won't be able to communicate for internet.

You could check the incoming wire to see if it is running off an amplifier. If it is you would need to run a new line that is not on the amplifier. I would recommend comcast coming out to check the signal frequency and make the necessary adjustments.

SOURCE: Ethernet light blinks no Internet

Serveral soultions to try and they are at no cost to you. First, try re-booting the modem. Your modem stores cache just like a computer does, and it can build up on you. I myself unplug mine about once a week.. Two, in the control panel under Internet Opetion under browser history click on delete and confirm the delete, this will delete your temp. files. You might have exceeded the amount of cache allowed by windows. Finally make certain that you have ipx, and spx protocol installed on your comuter. If this doesn't help, I would get a new modem from your isp, more than likely it is bad. I know verizon modem are good for maximum of 2 years and average 1 year. I would recommend westell 6100 G moem and get a wireless router to go with.

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.

My motorola SURFboard SB5101 has a on power light, a blinking recieve light, and an on PC/Activity light, with the other lights off. what is wrong with it?


The light pattern you have described indicates that the modem can not establish a connection to your internet service provider (ISP). This is typically do to a signal related issue. To trouble shoot the problem you will need to connect the modem directly to the main cable line where it first enters into the home. You will know when the modem establishes a connection by the top 4 lights becoming green. If at any point all 4 top green lights start to blink in sequence than you will need to contact your internet service provider to "unwall the modem". Remember most internet service providers require you to register your modem on there network. So if you have not all ready completed that process you will most likely not have access.

I hope that information above has helped is some way.

All the leds are lit up but the online led keeps blinking.


This light pattern indicates that the modem can not establish a connection to your internet service provider (ISP). This is typically do to a signal related issue. To trouble shoot the problem you will need to connect the modem directly to the main cable line where it first enters into the home. This process is known as bypassing the splitters. You will know when the modem establishes a connection by the top 4 lights becoming solid green. If bypassing your splitters resolved the issue than you will need to replace the malfunctioning splitter. Typically splitter only cost a few bucks and can be purchased from any electronic store. If at any point all 4 top green lights start to blink in sequence than you will need to contact your internet service provider to "unwall the modem". Remember most internet service providers require you to register new modems on there network. So if you have not all ready completed that process you will most likely not have access.
