Ethernet Port failure new router

I recently purchased and installed a Netgear router with my Surfboard modem and all was well for a week, then the ethernet cable running from my router to the desktop has apparently failed. Prior to that I had the modem with an ethernet cable going from the modem to the desktop. The new wireless router allows for 1 wireless laptop, 1 phone modem, and I have an ethernet cable connected to the desktop. Why would the laptop, phone, & desktop work all work well for a week, then all of the sudden the only thing not working is the desktop. The modem & router have to be working since the wireless laptop & phone modem are working. I can't figure out why the hard wired ethernet cable from the router to the desktop isn't working. Any ideas?

    Thanks for the tip. I just found out what the problem was after much research. I will paste it below for anyone else experiencing similar problems.



    Overview : Microsoft Update KB951748 is known to cause loss of internet access for ZoneAlarm users on Windows XP/2000. Windows Vista users are not affected.



    Can you believe that?

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.

I want to plug in another wireless router into my surfboard modem and have the wireless router work as well as the surfboard. Is there a way to do this successfully?


Yes this is possiable. First you need to unplug the power to the Motorola and the new router. Second connect the ethernet cable from the Motorola to the internet port on your second router. This port may be colored in yellow, marked as modem, or the ethernet port by its self. Third connect a ethernet cable from the new router to a desktop or laptop this is only to configure the new router. Next power on the Motorola and wait for the online light to become solid. Then plug in the power to the new router. Give the router about two minutes to obtain ip address from the motorola then try to get on the internet with the pc connected with the ethernet cable. Now you can run the new router setup cd on the wired pc to setup router. Once completed remove ethernet cable to the pc and connect to either network you have and you are good to go. Any questions just ask.

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.

Netgear WGR614 router with USB Cable Modem


When working with routers, CAT-5 cables are the more usual cable used. Your modem's Ethernet Port --- connect it via cable to the router's WAN input. Connect one of the router's LAN outputs to your computer's LAN input with another CAT-5 cable. Go through the appropriate Router Setup by putting http://192.168.1.1 into your Internet Explorer, with ' admin ' for User Name, and no password (just press Enter in Password frame). Once you are in to the router setup, you can select your Network Name (SSID) and then implement whatever Security you might want to use. You should be up and running by now, nhave lots of fun!

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.

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.
