NIC blinks on then off for longer run lines

I'm in Iraq, trying to set up a VSAT network for a group of soldiers. I have the sat system working fine. I ran cat5e to several locations, when I hook up any location farther than 40 feet from the switch, the lights on their NIC card and on the switch will blink on then off very slowly. The computer on other end will flash the notification that a network cable is unplugged. Is this my cable? I have tested the cable with a pin tester that cycles through all 8 pins on both ends to confirm you attached rj45 properly, according to this I get signal through the wire, it just might not be strong enough or maybe there's interference. This has happened with five different cables. I'm using cat5e utp

    I have checked the rj45's and my wires are good. I think I just had a bad box of cable. There's probably some cracks in the wire which may explain the wire tester still working b/c theres still continuity, but if theres cracks inside the wire then I'm dropping packets. I will run new cable to try to fix. Thanks for your help though.

Please make sure your not using cross-over cables and are using strait cables. Makes a big difference.

Please check the RJ45 plugs. the wiring should be as follows: RG45 connector side#1 legs 1236 goes to RG45 connector side#2 legs 1236 see the colors of the wires they should be equal

Network Interface is out of service


You can try resetting the NIC for future reference.

You'll need to print a NIC page first. Here are instructions on how to do that:
Print NIC Page with Network Info

Then go to the machine and do the following:

System Settings
Admin Password
The default password is admin
ok, ok
Network settings
Scroll down to Reset the NIC, execute.

Once the machine has rebooted go back to the network settings, then IP address settings. Uncheck the DHCP box then enter the IP address, Subnet Mask, and IP gateway from the NIC page you printed out.

Hope this helps.

Have you checked firewall settings. It's possible that the Server's OS has a firewall blocking pings and\or the server is running antivirus software that has a firewall setup again blocking pings.

You will need to readdress the remote to your receiver. I have provided instructions on how to readdress the remote. I hope this helps.

  • Remote: All Other Remotes
    1. Go to System Info screen
    2. Hold down the SAT button until all mode lights light up.
    3. Enter a number between 1 and 15 using the numeric keypad on the remote.
    4. Press the pound (#) button
    5. Once the SAT button blinks three times, press record. Note: If successful the number selected in step 3 will appear in the System Info screen under Remote Address.

Can I add a NIC card to my compaq presario pc sr5250nx? I keep loosing my internet connection every five minutes and have to reboot the computer to reconnect


you should be able to
http://h10032.www1.hp.com/ctg/Manual/c00840496.pdf

if your system is still within warranty I would think twice about opening the case yourself to installing a new network card.. you will be voiding your warranty.. so think about it

another thing i would try before deciding on going for another network card is to check your onboard network adapter has updated drivers... or you may want to reinstall the drivers for that adapter.. either one of those may probably fix your issue assuming is not a hardware failing given that your system may not be that old.... make sure you check the windows update and look for any new hardware driver for your network adapter that may be avaliable through windows update.

before you install your new network pci card you may have/want to disable the one on board going into your bios for that. so to ensure there's no resource conflicts when installing the driver for your new card (it may not be a problem even if you don't but if you run into problems while installing the new card consider this suggestion)

NIC blinks on then off for longer run lines


You need to update the firmware of the router then hard reset it.

Download the router's firmware at www.linksys.com/download

After updating the firmware, you need to hard reset the router.

Press the reset button at the back of the router for 30 seconds then unplug the power for 30 secs then plug it back in. That should fix it.

Rear NIC Light blinking


I found one of these printers in a parts bin and it looked like it was in great condition so I said what the heck, I'll try it out. Had the blinking light problem and figured it was a nic card because all functions via USB worked fine. If I plugged in a network cable, it froze up all functions except the LCD menu.

Took off the side panel and low and behold, it had taken a bad fall and the NIC card's connector to the main borad was busted. The main borad was fine though so it does everything fine via USB. Its a modulear NIC card so replacing it would probably work, but the chance of finding a replacement NIC card for the printer? Slim to none, it doesnt even have a model number. Only if I come across another one of these printers. Oh well, sweet printer for free, even if it only works via USB.
