Question about Arris SURFboard SB4200 Modem

1 Answer

Wireless routers Got my pc connected to a Motorola SB4200 modem via usb. Internet works fine. Bought a Netgear WGR614 v7 wireless router for wireless internet connection on my new laptop. Removed the pc as its gone to a friend. Do i unplug the usb connection and discard it then connect the moto and netgear together via ethernet. Will my new laptop then just attach itself wirelessly to the router. Googling seems to suggest the moto is not compatibla with the netgear as the moto is a usb modem but it has an ethernet plug on the back. plz help, Keith

Re: wireless routers

Just plug the cable modem ethernet into the input to your router and you will be fine. Just remember, if you decide you want to make any changes to your router settings through your browser, make sure you hook up an ethernet line from your laptop to the router before making any changes. The reason for this is if you make a change in security settings on your router while wireless, the router will reboot and if your laptop did have the settings changed in it, you can be locked out.
Not that you can't get back in, but it is a pain to have to do.

I have a motorola sb4200 cable modem that was working just fine until 3 days ago the power light is steady and the send and receive lights alternative in blinking and being steady none of the other lights...

Thank you for the detailed information. Not having internet can be frustrating! If the "Online" light is not turning on, that means it is not obtaining an IP address from your internet service provider. Since the "send" and "receive" lights are blinking, this means the coaxial cable (Tv cable) is screwed in.

I would suggest finding a phone number for your internet service provider to assist you further. There may be a service outage in your general area, or there may be a localize issue. They may have to go through troubleshooting with you over the phone, so you may have to unplug the modem, and maybe even bypass the Netgear router to troubleshoot with them. If the issue cannot be resolved over the phone, they may need to send out a repair man to resolve your issue.

I got a NETGEAR router and I have been trying to get my Motorola SURFboard to recognize it. I had the USB connection installed and the NETGEAR uses ethernet, so I tried to install the ethernet but my...

The Cable modem must be disconnected from the computer. You cannot use USB and Ethernet at the same time.

1. Turn off power to the Cable Modem and the Netgear Router. Do the same with the computer.
2. Connect an ethernet cable from the modem to the router's WAN (Internet) port.
3. Connect another ethernet cable from one of the remaining 4 LAN ports on the router to the computer's ethernet port.

4. Now power on the Cable Modem ONLY. Wait for the modem to sync up with your service provider
5. After about 2-5 minutes power up the router and wait about 1-2 minutes.
6. Now power on your PC.

Check and see if you have internet access. If not you may have to uninstall any cable modem software related to USB connection. if this is the case, then you may have to repeat steps 4-6.

Since most cable internet providers do not use proprietary connection settings, your internet connection should be up and running without changing any settings in the router or modem.

If this does not resolve your issues, we can continue to work with you.

Trouble connecting netgear wireless router to rca modem DCM425

First try connection the Yellow ethernet cable from the rca modem to your computer's network connection. If you get a connection this way, then your modem will work with a ethernet cable. If not, then call Comcast for help. The modem ethernet out to computer port must be connected to the wan line of the router. Then you can connect an ethernet cable from your computer network connection to one of the 4 ports of the router. For wireless connections you must set up the router and wireless adaptor with the same settings to connect. Follow the routers directions.
Good Luck

The SB4200 Modem according to the Motorola website does NOT have wireless capabilities. In fact not a lot of cable modems do have wireless built in to them.

That is the modem to which you refered and it does not have wireless. In order to connect your Wii wirelessly you would need to purchase a WIRELESS ROUTER, which most major stores carry varios brands such as Linksys or Netgear.

Need to get wireless on my laptop,

No, the SB5100 is just a cable modem, not a wireless router. You will need to keep your sb5100 but you will need to purchase a wireless router if you want wireless on your laptop. If you can also plug your laptop into the sb5100 via an ethernet cable for your internet connection. Linksys and Belkin and others make wireless routers that you can use for your wireless connections.

Motorola Surfboard 4220 not working with my Netgear WGT624 router

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.
