For some reason all of a sudden my computer isn't recognizing that my ethernet cable is plugged in. The modem and router work fine, and tested the cable on another computer and it worked fine, so must be the computer, but can't figure out why it can't see that the cable is plugged in.
It's the card itself. It probably went bad. Go to Walmart and pick one up for about $15. I had this happen a few weeks ago, All cables are good just wouldn't connect to internet. It's the ethernet card itself, they do go bad.

Re: computer not recognizing ethernet cable
I agree with bambi541 that it's probably the ethernet device. To replace it you need to determine if it's an add-on card or the built-in kind. It depends upon what type of box you have. If it's a tower, the CD and floppy drives are near the top and the power button is near the middle or lower down If it's a "pizza box", it lays flat on your desktop and you usually put your monitor on top of it. Looking at the back of the computer, if it's an add-on card, it'll be either on the bottom half of your computer or to the right, close to the keyboard and mouse connections. If it's built-in, you should disable it in the BIOS. If you don't know how, I'm pretty sure you can get by without disabling it, but it'll keep showing the "bad" icon as well as the new one. You might have to install some software with it, but XP is pretty smart with new stuff and may not need it. Just check the instructions. (You just need any 100MB ethernet card and it will be pretty cheap.)

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.
You need to check the router's admin page to make sure the DSL/Cable modem is being recognized properly. This can happen when unplugging the devices. Ck your routers user manual for login instructions. Should be default IP address of router typed into internet explorer browser then you need login/password (like admin/admin) then check the status to see if router/modem are talking to each other. Probably good idea to unplug both devices at the same time and then power back up. I can be more specific if necessary.
unless you were switching from DSL to cable Broadband, there usually wouldnt be much reason to rerun the software just because you got a new computer. when you ran the software the first time on the other computer, it was the router you were setting up, not the computer. if the new computer is not getting internet when hooked to the router, try this.
1.turn off computer and unplug electricity from router and cable modem.
2. connect all ethernet cable to the right location. ethernet from modem to router goes in the non-numbered port, ethernet from your computer to router goes in numbered port.
3. plug in cable modem electricity first, wait for all its lights to come on like normal.(this part is important). the ethernet light on the modem (it might be labeled ethernet, link, pc link, or something similar) will not be lit, this is normal until you get to the next step
4. plug in the router electricity, give the router 2-3 minutes to get connected to the modem.
5. start up the computer, wait for everything to fully load and check internet again.
the prob may b with the ethernet adapter on the computer or the ethernet port on the modem or the ethernet cable.....

to check the ethernet cable
try with an alt cable which is proved to be working
-- who is your internet service provider -- what is the operating system of your computer? -- is this working fine before or is this a brand new router
you may try this and see if this help solve your problem. make sure your computer is directly connected to the router
Step 1: Shutdown the computer. Step 2: reset the router while power on then Unplug the router’s power cable. Step 3: Unplug the Broadband modem’s power cable and wait for 30 seconds. Step 4: Plug in the Broadband modem’s power cable and wait for its lights to appear stable. Step 5: Plug in the router's power cable once the modem’s lights appear stable. Step 6: Power on the computer on and configure the router settings Step 7: test the Internet connection.
if this still didnot work, upgrade the firmware of your router
FYI for those people trying to use a ethernet and usb cable from a cable modem - it may work for a while but it won't work forever - your ISP will only allow one IP address out of the modem unless you pay for additional addresses (then you need a switch). Each device you have on the modem is fighting for that IP and eventually it will just quit working (if it works at all).
If you want more than one computer on your network (on the Internet or sharing printers/files, etc) then you need a router or a gateway (cable modem/router combo which I DON'T recommend).
