After having some problems with my internet access I was sold that my internal ethernet card was dead. I purchased a new Linksys Etherfast card and it is installed and recognized by my Dell Demension 4550. I plug in the cable and I can not get internat access. I know it works, because I am using it on my Mac. HELP.
when you plug the cable in are you doing this with the system on or off? If it is on that may be the problem. the router and or modem cannot assign you a DHCP address.
You may be on to something. When I leave the computer on and plug in the line the computer says "accessing IP address" and does not then says limited or no connectivity. When reboot the computer with the line plugged in the computer recognized both ethernet cards. In the tool bar it says "connection 6. unplugged" and connection 3, 100 Mbps, limited or no connectivity.
It is not yet working, and may be tied to it seeing both cards. Thoughts??
Having two active connections might be the cause of your issue. I would open the network connections and disable the one that you are not using. Also check the properties of the one you want to use to make sure it is set to obtain ip address automatically.
