Loosing Internet Connectivity

Discussion in 'Windows Vista Networking' started by Dustin Brown, Sep 20, 2007.

  1. Hi Barb, I went to device mgr. and there is no power management fo
    Westell, however I do have some good news. I uninstalled the Westel
    drivers etc. and unpluged everything and then placed the CD fro
    centurytel in and ran the complete program following the on scree
    instructions as well as those provided with the modem and have put th
    computer to sleep around 5 or 6 times and it is working OK. The US
    light stills goes out when computer goes to sleep but it comes on a
    soon as it awakes and the internet connection is there. YES I do hav
    the LAN and it is marked ETHERNET. This was what I was using before. I
    is empty,there is nothing connected to it. Thank You

    glad the USB is working. however, it looks like the Ethernet
    connection may have gotten fried during that power surge. There is
    no way of knowing if other areas of the motherboard may have been
    impacted, etc. If the computer is under warranty, you should really
    consider having this looked at.

  3. Thank You Barb, I will contact HP and see what they will do. One
    question when I go to device mgr. and right click on properties then
    Advanced on the left under property highlighted in blue is "Network
    Address" on the right is "Value", which has a blank space for a address
    and below that is not present which is checked. Should I enter a value
    for the address? THANK YOU. By the way no internet this morning, but I
    am up and running again, now where is HP telephone number??? Thanks
    Again.

  5. Hello Barb, I hope You could help me too. I have a very same problem with
    internet connectivity as Dustin Brown who started this thread. I can easily
    connect every time, but every few hours I loose connection, simetimes access
    is marked as "local only" , but sometimes as "local and internet". I can
    solve it sometimes by restarting the Windows, sometimes by reseting the
    router and other time by reseting the LAN adapter. My Vista Home Premium was
    working well for almost 10 months but few months ago this problem occurs for
    the first time. I have automatic updates turn on and I have strong suspicion
    that this problem started after one of the Vista updates during
    October-November 2007. I have this problem on desktop PC with wired
    connection but wireless has this problem even more often so I don't use it at
    all. My laptop with XP works well on wireless connection. My processor is
    Intel Pentium D CPU 3.40 GHz 3.4GHz,memory(RAM) 3071MB,32-bit OS. My LAN
    adapter is Atheros L1 Gigabit Ethernet 10/100Base-T Controller. Antivirus is
    AVG. Since the problem begin I have changed three diferent routers (Siemens
    Gigaset SE-555, Zyxel P-600HW D-3 and now I have D-Link DSL-G684T). I can not
    use anything else because that is what my service provider gives me and I
    have IP-TV through same router. Firmware is also provided by my service
    provider and must have support for IP-TV. EGD Evaluations tests are all
    "suported" except test 5 - UPnP support test- which is not supported.
    I tried disabling TCP IPv6 adress and QoS Packet Scheduler and Link-Layer
    Topology Discovery I/O Driver with no result. Since I have started to use
    static IP adress numbers of disconnections reduces so I continue to use
    static IP adress on my LAN adapter.

    I still see IPv6 -
    http://digitalmediaphile.wordpress.com/ipv6-how-to-unbind-from-a-nic-in-windows-vista/

    there have been lots of reports on issues with drivers from WU for
    the Atheros L1 Gigabit Ethernet NIC.

    go into device manager - expand the properties for the NIC and roll
    back to the older driver. if there are multiple drivers presented,
    picked the one that worked up until a few months ago.

  7. Thank You for Your prompt answer and yes, I still have IPv6 marked because
    disabling it didn't achieved any result at all. I'll try go back to old
    Atheros driver but I thik that some of the Vista updates produces this
    problem with internet connectivity, not NIC driver update. I have updated
    NIC driver AFTER problem started, trying to solve the problem, not before!
    Thank You anyway.

  8. Hello Barb, I wanted to let you know that HP took care of the problem.
    They had me send the Computer in and they replaced the motherboard. As
    soon as I hooked everything up ETHERNET was there and has been every
    sense. HP paid all costs and a big thank you to Barb.

  10. Hi Barb,

    I've been having an issue very much like the ones described in this thread
    ever since I purchased my Dell Inspiron 1420 laptop last month, except that
    my problem occurs when I'm on a wired connection, not a wireless one. After
    getting the computer out of the box I plugged in the Ethernet cable and was
    able to get online w/o a problem. I let Windows Update download and install
    multiple security updates and hotfixes, after which I began experiencing
    dropped connectivity. Thinking that one of the updates might be the problem,
    I did a clean restore of the OS from the included CD, but the problem has
    continued. After (usually) a few hours online, my connection will drop and
    the network status icon will show a yellow triangle with an exclamation point
    in it. If I do a mouseover, it says my access is Limited (or maybe just
    Local - I can check when it happens again). I have called Dell and my ISP,
    and nothing they suggested has solved the problem. The only thing that seems
    to work is a reboot.

    My network adapter is a Broadcom NetLink Fast Ethernet running what I
    believe to be the latest drivers. I've tried resetting the adapter,
    requesting a new IP address, everything I can think of (and I think most
    suggestions made here), but all to no avail. The output of my ipconfig/all
    is below; I would appreciate any suggestions you have for me.

    Thank you!

    Should be:
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    change 4 to 5

  12. Hi Bob,

    How would I change the subnet mask manually? Isn't all that assigned
    automatically by Comcast? I'm assuming it's in the Network and Sharing
    Center somewhere, but I'm not sure where.

    Thanks,

    Tait

    Yes, my error, I should have looked closer and noticed that this was
    assigned automatically. But it sure does look strange. OTOH, It also could
    be causing the problem you are talking about. ?? Keep an eye on it. You
    could go into your command prompt window and type "ipconfig /release"
    followed by "ipconfig / renew" (no quotes) and see if you get different
    numbers.

    Comcast can assign different subnet masks so don't worry about that
    at all.

    Check your power management settings. In device manager, is the box
    checked to turn off power on the NIC? Can you also try running with
    the high power option to rule out any other power management
    options?

    Comcast assigns different scopes on each CMTS. This is not causing
    an issue of any kind and is absolutely normal.

  16. Hi Barb,

    I unchecked that box in Device Manager a few days ago when I ran across it
    as a possible solution on a different website. So far, it hasn't made a
    difference. I did change my power plan to High Performace as you suggested;
    I'll let you know if the problem persists after the change.

    Thanks,

    Tait

  17. Hi Barb,

    Changing the power plan doesn't seem to have helped. I was online for quite
    a while yesterday (a little over 6 hours, the longest continuous stretch so
    far, I believe), and hoped that maybe the problem was fixed. Unfortunately,
    my connection did eventually drop. The problem isn't with Comcast or my
    cable modem, as far as I can tell. The light on the modem that shows my
    internet connection stays steady green, so I know that's OK, and the
    send/receive lights continue flickering with activity even after the computer
    says the connection has been lost. It's like something in the computer
    eventually decides it doesn't want to talk to the modem anymore, even though
    the info is still coming in. I'm stumped.

    Thanks,
    Tait

    What the model# of your Broadcom NetLink Fast Ethernet. There are a series
    of drivers that came out 2/27/08. Do you really have the latest?

    I hate to do this, maybe just a witch hunt, but can you tell us exactly what
    component (model #s) are in your network and exactly how it's all wired
    together? I am looking for looping, things plugged into wrong sockets, old
    hardware, stubs, things like that.
