    Hello,

    While I am in CA, I was helping my brother with his Dell computer, to get it re attached to the network (He had every version of spyware on his comp possible, so I formatted and reinstalled everything). He is connected to a router that is connected to cable internet. Anyway, the problem is that the "net work status" will show the link is connected, then disconnected, then connected, etc etc.

    It will stay connected for about 3 seconds, then say it was "unplugged", then say it is connected again, cycling every 3 seconds into eternity. I tried mimicking the settings for the other computers on the network and nothing seems to help. I know there is a simple solution for this as I have dealt with this problem before, but it has been a while. Any help is appreciated.

    A couple friends have this "problem" We've come to the conclusion that the answer is to turn off the announcement of the cable status so we don't see the notices every tenth of a second.

    Do you actually have slowdown? Do you see hiccups in the traffic? Do you see anything other than the notices?

    The status turning off and on like it is is indicitive of the fact the router is disconnecting the cable, or something. The internet does not work at all. For some reason it just constantly connects and disconnects ever 3 seconds.

    Reinstall the NIC driver.

    Start, run, type in ipconfig / release[i/] and press enter, then type ipconfig /renew and press enter.

    Also, make sure the computers name is unique on the network.

    possibly a bad:
    nic card
    router port
    patch cable

    when you tried to mimic the problem with one of the other computers, did you connect the known good computer to the router port of the pc that is having the problem ??

    Turn off 802.1x authentication. Make sure all three checkboxes are empty on that properties screen for the NIC. The Os is polling the router in attempts to authenticate, and since its only a little home router - it doesn't support that function.

    Control Panel - Network Connections - LAN, right click Properties - Authentication Tab - verify all 3 boxes are empty. You may have to temporarily check on the top box, then unecheck the middle box, uncheck the top box - Apply - OK - should be good to go.

    If its a WiFi connection that symptom usually means there are two wireless networks within range of each other that are trying to use the same SSID. Solution is to set a unique SSID for the local wireless group.
