After an electrical outage, my system no longer recognizes my Network cams. I're tried resetting them using an ethernet cable, but still no luck. Any suggestions?

Hi there,
The LAN lights will only turn on once you have an Ethernet cable connected to it and the other end of the cable is connected to a working computer.
If you already have a computer connected to the Ethernet port of the router via an Ethernet cable and the lights are still off. Check if the computer you have connected recognizes a network via LAN.
If the lights on the router are still off and the computer doesn't recognize a network then that means that the port for the ethernet of your Router is bad and sadly there's no way of getting that fixed but to have the router replaced.
Otherwise if the lights are off and the computer recognizes the Network and lets you connect to the internet or other computers on the same network then its just the LED of the LAN light that's broken and I think you can live with that.
Hope this helps!

Did you try direct wiring the other pcs to see if they will connect separately? If they won't then check the network settings on each pc that won't connect. Make sure that the gateway address is the same ip address as the router is.

Did it work before the outage, all of them at once? If so go to the Command Prompt (RUN, type in cmd, enter and a small window will pop up), and where the cursor is blinking type in - ipconfig - (some win versions use winipcfg) , hit ENTER. That will tell you what address are set to. It should say 192.168.xxx.xxx.
Type in - ipconfig /release - ENTER. That will reset the addresses which should now all be zeros.
Now type in - ipconfig /renew - (make sure you have the blank space between the g and the /). This should give you the 192.168.xxx.xxx address for IP if your network settings are set correctly under Network Connections- Properties-TCP/IP

Sometimes under outages you need to reset both the modem, the router and the pcs to acquire the new addresses.

Try another Ethernet card (adapter) for the PCI slot. The onboard adapter maybe "shot".

Try reseting the hard drive - cycle the power or unplug it for a minute then plug it back in.

1. check connection by 1st pinging the network card That is go to the dos window and type " ping 127.0.0.1 you should get 4 replies.
if not then you need to check the driver set for you network card.
2. check the ether net cord with a know good one
3. reset the router by unplugging it and reboot the pc
4.Call your ISP to check for outages
5. check the power adapter it may be faulty.

Hi,
If you are connecting to the switch using network cable (not usb type), then you don't need software. Just hook up the cable to use it. If your system is not recognizing the switch. then may be you have to install network Lan adapter driver to your network card present in your machine(PC)

I hope this is helpful to you
Thanks

If you cannot connect your laptop using an Ethernet cable, make sure the laptop's wireless ethernet is disabled. To disable it in window xp, click the Start button and open the Control Panel. Double-click Network Connections. Right-click Wireless Network Connection and select Disable from the drop-down list.

If you are using a laptop with Windows Vista, click the Start Button and type Network and Sharing into the Start Search box. Select Network and Sharing Center from the Programs list. Select Manage Network Connections from the left pane of the window. The Network Connections window will open. Click on Wireless Network Connection. Select Disable this Network Device at the top of the window.

Troubleshoot the Network
After disabling the laptop's wireless connection, be sure to restart the computer before trying to connect with the Ethernet cable again. If you still cannot connect the laptop to the network with an Ethernet cable after rebooting, check to make sure there is not a problem with the network itself. If there are others nearby connected to the same network, such as in your office, dorm or another public location, ask them whether they are currently able to connect to the network. If no one else is using the network, contact the system administrator or your Internet service provider to see if there may be an outage. This step can save you plenty of time troubleshooting if there is an outage in your area!
Troubleshoot the Ethernet Cable
If there is no problem with the network itself, the reason that you cannot connect the laptop may be the ethernet cable. Make sure that the Ethernet Cable is securely connected to both the laptop and the wall outlet. If possible, try connecting the Ethernet cable into another wall jack or port on the router, and then try using a different Ethernet cable. The Ethernet cable you are using may be damaged.


Troubleshoot Network Settings
If the Ethernet cable does not seem to be the reason why you cannot connect to the network, check the laptop's network settings. In Windows XP, open the Control Panel and select Network Connections. Open Local Area Connection and check the status of the connection.
In Windows Vista, go to the Network and Sharing Center and select Diagnose and Repair from the left pane and wait for the results.


If the Local Area Connection is listed as Disabled, right-click it and choose Enable.
If it says that the network adapter is unplugged and you have ruled out a problem with the Ethernet cable and port, the laptop's network adapter may have failed. Try using the same Ethernet cable on another computer. If you are able to connect to the network on another computer using the same Ethernet cord, contact the laptop's manufacturer, a computer repair technician or replace the network adapter yourself.

Very well could have toasted you network card. If everything else works, try installing a different one (and drivers) that is known to work. MM85
