how do i fix my modem to get it to communicate with my ethernet port? it was running fine yesterday, but today will not talk to ether net. I have to run it on usb port, and irts fine. also will it be ok on usb? it is a cable modem. i just did a speed tesyt and it is dl at good speeds, but prefer ethernet.. could it be my cat cable went out or is that possible?
click up a CMD termainal, ipconfig /release /all Remove power from cable modem for 15 seconds by your clock. remove your ethernet and usb cable from modem. Power up cable modem, wait for leds to return to normal. Plug in ethernet cable.
ipconfig /renew
try doing a ping http://192.168.100.1 That is a web page server in Motorola SB4xx or SB5xx cable modem. if works, you can talk at the cable modem on ethernet.
If your modem leds are looking normal and you can get to the cable modem web page your 90% doing good. If the top leds are not on solid you have cable signal problems. The other problem maybe signal levels.
If you can ping 66.94.234.13, you are connected to the internet and doing 99% good. If that ping works and ping yahoo.com fails, your DNS servers are AFU.
Since I do not do windows, I cannot help you.
Next chance you get, download a knoppix iso and burn to cd. boot cd set dhcp on ethernet and use a public dns server.

If that stays on solid, you know it is software.
Always helps to get a second opinion to rule out hardware.
Anytime you change the hardware connected to the cable modem, you have to power reset the cable modem at least 15 seconds just to talk to the modem.
Those are normal on a booted cable modem. You need to show your up/down stream signal values to rule cable modem connectivity.
You have to get to known state to trouble shoot your problem. Get the knoppix to rule out hardware and software.
Well if USB works SOLID, that indicates the cable modem connection is working.
Does not rule out ethernet port side of modem.
I hear that. Viruses are trying to disable those. :(
Buy or get a friend to burn a knoppix cd to help you rule out hardware problems.
