| 734385 | 2009-01-02 08:48:00 | I have a small home network with two desktops connected to a Dynalink Modem router with a laptop connected to the router via a wireless Linksys access. All has been working fine but on the 27th or 28th of December (5 or 6 days ago) one computer came up with “Local area connection. A network cable is unplugged”. This flashes on and off at about one second intervals in an annoying little box in the bottom right hand side of the screen. At the network cable plug there is continuous green light on the good computer and flashing yellow and orange lights on the problem computer. All computers are running XP SP3 with Norton 360 & IE7. I’ve tried swapping the cable from the router-good computer to the router–problem computer and it still doesn’t work. I’ve swapped the cable from the problem computer to the good computer and it works fine. I’ve also moved the cables around on the router. Suggests it’s the computer not the router or cable? I’ve rebooted everything umpteen times as well as the router etc etc. It seems to me like the problem computer is trying to connect but can’t. Why? There are two LAN connections Local area connection using a NVIDIAnForce networking controller which produces the problem. If I hit the repair button it says “windows couldn’t finish repairing the problem because the following action can’t be completed – renewing your ip address” 1394 connection using the 1394 net adaptor. If I enable this connection then I don’t get any “network cable unplugged” notice but then I don’t get any network connection at all!! Hitting repair I get “windows couldn’t finish repairing the problem because the following action can’t be completed – failed to query tcp/ip settings of the connection” In both cases I have tcp/ip settings set to be found automatically. Is this wrong? Its what I’ve got on the other computers and they work fine I’ve googled until I’m blue in the face but haven’t found anything quite like this that has been solved. Is it something that has come as a result of an automatic Microsoft update? Is it a clash with Nortons somehow (I have turned off Nortons but that hasn’t changed anything)? Is it a clash with some HP update (HP seems to clash a lot lately)? Any help greatly appreciated |

| 734386 | 2009-01-02 08:52:00 | 1394 is firewire. I would leave this adapter alone Is Nvidia firewall installed? If it is uninstall it |

| 734387 | 2009-01-02 09:30:00 | Yeah 1394 is firewire and that has nothing to do with your network . By the sounds of things I'd say the NIC (network card) on the PC is faulty or the drivers got corrupted . Try going into device manager and uninstall the network adapter, then download/reinstall the driver for it . If it still doesn't work try connecting the laptop or the other working PC straight to the problem-computer . Make sure you use a crossover cable . Set the IPs/masks manually on the two machines (TCP/IP settings) and try pinging between them . If that doesn't work you know its a faulty NIC . Gregor |

| 734388 | 2009-01-02 11:07:00 | I had a similar issue a couple of times last week :( Both times, I reloaded my router file from my HDD and rebooted the router. Normality was resumed :) |

| 734389 | 2009-01-02 20:00:00 | If it's desktop you could put in a PCI/e NIC if the onboard one is stuffed | gary67 (56) | ||
| 734390 | 2009-01-02 20:10:00 | firstly does your network connection physically drop out try from cmd prompt ping -t (your Router Ip) If you get this message (pop up one) with out losing connection Ie "No reply" from the ping command, then just disable notifications on the 1394 device. Yes for som e reason only known to Microsoft the firewire device is treated as a network card by the os |

| 734391 | 2009-01-03 08:33:00 | Thanks for all your replies Speedy - Nvidia firewall wasn't installed WarNox - I've uninstalled the driver and reinstalled. No difference. Haven't got a crossover cable so can't try that one Zippity - How do I reload my router file from my HDD? Gary 67 - Installing a PCI/e NIC sounds a bit complicated for me!! Beama - Network is almost continually out. Two days ago I got a 50 % return on packets. Today all I get is "destination host unreachable". 1394 is disabled. Still no change. In the course of searching the internet I came across a similar problem and the guy said that even though he swapped cables on the router with no change (only the one computer affected) so that it looked like the computer was at fault he bought a new router and his problem was solved. Today I have been having slow wireless connection from the router. Could it be the router after all?!! |

| 734392 | 2009-01-03 08:43:00 | Look on the back of both PCs is the LED on the NIC flashing as well? Put the ips in manually on both. And put the ips for the router as the gateway (And your DNS ips for preferred / alternate DNS servers) And make sure both have the same workgroup name Or get a modem/wireless router in 1, instead of 2 different things. Thats probably whats causing it |

| 734393 | 2009-01-03 09:00:00 | But why isn't it working now when it was working perfectly OK a week ago? | ecurb (3669) | ||
| 734394 | 2009-01-03 09:03:00 | So, Norton 360 is on all 3?? If it is, I would go into its options, wherever the network stuff is, (for the LAN/network) delete it then let it pick the network up again and let it readd it Dont ask me where this is, I dont use any Norton programs |
