Ethernet NIC card not seen in Network adapter (code 31)
Hi! Had a lightning strike close to house last week. Was watching TV when it happened without a warning and heard a Pop at the cable modem and everything went off. Cut all power to everything at that point but when next time I tried to use my laptop could not see the LAN connection in Network connections via the Marvel yukon miniport fast ethernet nic(?). Doesn't show up when plugging the cable from the modem to the laptop. Loaded the drivers again from the disc and get yellow exclaimation point (code 31) in the network adapter folder in Device Manager. I'm assuming I have a hardware problem, but haven't taken the laptop apart yet hoping another fix is possible. Thanks!

Attach a Ethernet cable to the laptop, Open Device Manager, Network Adapters, Uninstall the Wireless adapter, reboot, Allow the software to apply the generic driver, try to connect to wireless network. Post results.
there is no driver installed for your adapter. check in device manager click on network adapters.you may have to connect to internet with ethernet cord before you can download a driver for your adapter.
Yes, most likely the onboard LAN card has been fried by the lightning. Disable it from Control Panel - Network Connections then uninstall its driver from Programs. Then buy and install one of these
You can click Start > right click My Computer > then click Properties > and then click Hardware, > then click Device manager > then Under Network Adpaters, click the (+) sign and check if the Intel ethernet card or Broadcom Ethernet card is off. If it is off, then right click the device and click Enable. If it is still off, you may download a broadcom or a intel ethernet driver so that it would update the NIC card. You can check out the intel.com or broadcom.com for downloading instructions. If symptom still persist then contact Dell to set an appointment with a technician to check your NIC card inside your laptop for possible repair.
Not much to go on with your question. Windows 7 does not see your network adapter(s). Did you just upgrade? If so, you might need to go back to Dell website and download the Win7 drivers for you laptop. On that laptop you should see 3 network interfaces for WiFi, Ethernet, and the modem, and possibly a 4th for bluetooth. Dell is pretty good with downloads - just type in your service code at their support site, and they will only show you what you might need for your computer.
Check the ethernet port with other spare wire if you have to check if it is a wire problem or if it is itself your ethernet port.
Try to connect your ethernet port directly to the router to make sure ethernet port is working and there is no connectivity issue with the switch.
Try to check the System BIOS settings and see if it is not disabled from there.
Lastly download any free Live OS of Linux and boot your computer using it. See if the ethernet card is working or not.
Steps from 1-3 is for checking physical connectivity of the ethernet port and the last step is for checking OS issue. If network card do not work with Live OS as well, you can directly come to conclusion that its ethernet card that is not working properly and you need to get is repaired.
I would take you laptop to a local store/repair shop and ask them if you can try the PCMCIA NIC in your system to make sure that there is not something else wrong. They should do this either free of for a nominal cost. This way you can check to make sure your system recognizes the NIC card and also that the correct driver is loaded.
Maybe your problem is software related. Maybe a virus changed some settings. I would check all the internet settings and the network card settings. I've seen this happen before. In windows xp click Start/Control Panel/Network Connections. Then right click on your local area connection and Click Properties. Slide the bar down to the TCPIP protocol and highlight it, then click Properties. Make sure you are obtaining the IP Address and DSN Server address automatically. Click the Advanced button and make sure DHCP is enabled.
yeah i dont think there are still available drivers for your computer,if you can only specify the name of the integraded nic card,it will be easier for us to look for it,if you still want to connect to the internet using ethernet,you can buy an ethernet to usb adapter,in that way,your usb port will be converted lke an ethernet port on your computer..or if your router or modem has usb connection,you can also connect it directly to its usb port provided that you have the drivers from your router/modem
