ethernet problem..any suggestions??

[krnjason]

hi, i unplugged my ethernet cord from my desktop computer trying to connect my laptop, and when i went back to tried to plug the ethernet cord back into my destop pc, it wouldnt recognize my internet connection, although it works fine if i plugg it back into my laptop, is there a problem with my ethernet card?? or is it a driver or something missing.

I would reboot your router or modem and see if that helps. Some devices are picky about swapping out from one device to another. Good Luck

yea, ive rebooted my router switched the cord around but no go....im leaning towards replacing my ethernet card but, its kind of odd that it breaks right after i unplug the cord for a about an hour.... any other methods that i can try out.? before the cashing out option??

Have you tried rebooting the PC after the Change?

Remove the device from Device Manager, and reboot which should result in Windows either installing the device or prompting for drivers. Be sure you have drivers before doing this.

can you access the roters setup screen in your browser? ... if so the the problem is that you must reboot your modem (if you have a all in one roter/modem then you need to reboot the device) ... unplug power cord and wait 30 seconds before plugging back in ....

Most modems will only recognise the mac address of the first pc conected .. if you then switch to a different pc it will be neccessary to reboot the modem in order to get an internet connection ... in order to avoid this problem you need to go into the router setup screen and look for the setting 'clone mac address' ... set this to the mac address of your main computer and save the settings .... reboot the router (and modem if its a seperate device) now connect your other computers to the router and the modem will think it is still talking to the original computer and an internet connection will be available to all computers .... even if you unplug the ethernet lead from the main pc and plug it into your laptop you should still get an internet connection as the modem will think it is still talking to your main pc

rebooting of the machine should do it

Describe the device the PC is plugged into. If it is a cable modem, it MUST be powered down for 30 seconds before changing connection. These devices "lock on" to the first MAC address they see and will not accept another unless powered down to clear their "memory".

Is your IP address static or set to "obtain automatically"?

Can you ping the router, yourself, and a DNS server?

Are the "happy lights" on the back of the Network Interface Card (NIC) functioning?

Do the connectivity lights on the device which you will describe light up when the PC is connected?

Very unlikely your nic blew at that precise moment, but possible. Very probable that the problem lies in IP addressing or device recognition.
