I'm troubleshooting an issue with a Dell laptop not seeing any Wi-Fi networks, nor able to see when the Ethernet cable is connected, not receiving the IP either. Everything was working fine until I added more memory (total of 4Gb), but now the computer isn't able to connect with Wi-Fi or Ethernet.
I have tried to disable/enable the network adapter, uninstall the wifi driver and let it reinstall automatically, plug-in the network cable into the laptop, but it would show that "media is disconnected".. the lights are blinking on the NIC card though. Also tried restarting the computer.
I'm guessing that the issue may be with some Service not starting up? Could it be TCP/IP? - not sure how to troubleshoot/check that.
Please advice. Thank you in advance!
