G530 causes intermittent network Drops for all Machines on the network

I have a new G530 (Vista Home Premium, 3 GB of RAM) that will expose the weird behavior. Whenever he is on my home network, it causes all machines on the network to lose Internet connectivity for a few seconds every 30 seconds or more. Everything on the network is fine, and then I connect the G530 - either turn on the wireless switch or connect a cable. Therefore, network connectivity is interrupted periodically.

Here's what I know:

  • I have plugged and unplugged it for more than a week. It is this machine at the origin of the problem. I can repeat on order by commissioning wireless switch on Lenovo or plug the LAN cable.
  • The network works through a router DLink wireless/wired. The wireless part is encrypted WEP.
  • The machines on the network are a mix of Vista Premium, basic Vista, XP, Win2000 and a wireless HP printer. They all display the intermittent network problem when the Lenovo is connected.
  • Lenovo has the problem when it is connected.
  • I made repeated IPConfig / release--> / renew on all machines. At one point, I did a manual inspection and there is no duplicate IP addresses.
  • The Lenovo worked fine connected wireless to the network of the local public library.
  • A suggestion of DLink had to give the different names cable and wireless LANs. I tried. Problem persists.
  • It is not the modem; We went from LILY at the thought of this week of cable modem - thanks to some misleading advice from our DSL provider - the ADSL modem was dying. The problem is the same now with the cable modem as it was with the DSL modem.
  • I can see the problem on non-Vista machines easily because the task bar appears whenever the network connects or disconnects. (Vista has fixed this particular annoyance.) The message is that a network cable is unplugged.
  • It's the question even if the Lenovo is connected wirelessly or via Ethernet.

Any ideas? Thoughts? Suggestions? To cry on shoulders? Otherwise, it is a wonderful machine, but I need a computer, not a killer network...

Thank you

-Steve

I had a Linksys WRT54G Router go bad a few years ago that showed the same behavior.

  • Is it possible to have full control for all users in the directory/files/registry?

    Can I have a lot of control (read, write, change) my specific file / registry for all users, you have any program or script for this reason?

    as 'cacls '. Because I can't use cacls.

    is it wrong?

    C:\>Cacls "program * Files\NETAS" / c/r users: «F»»»

    Displays or modifies access control (ACL) of the files lists

    CACLS filename [/ t] [/ e] [/ c] [/G user: permission] [/R user [...]]
    [/P user: permission [...]] [/D user [...]]
    the ACL file name.
    / T changes ACLs of files specified in
    the current directory and all its subdirectories.
    /E Edit ACL instead of replace it.
    /C continue on access denied errors.
    /G user: permission Grant specified user access rights.
    Perm can be: R read
    W write
    C change (write)
    F full control
    ...

    Perhaps you could elaborate a little bit on "this command is not running"...  What happens when you try?

    I'm not knowledgeable about Windows 7, but Windows XP, I found the registry permissions must be put in a file.  So in your example, you can create a file named "z.txt", and in this file, you put the line:
    [1 5 7 17] \registry\Machine\Software
    Then call you the command line:
    Regini z.txt

  • Scanner does not work for all users on the computer Windows 7

    Photosmart 7510 Scanner does not work.  My scanner has the habit of work.   Now it does not for one of the three users on my Windows 7 desktop.

    I spent over 3 hours on the phone with HP.   They had me restart the computer, Plug and unplug the printer, reinstall the software twice under different names. The software depending on what user id, it is installed under allows access to the scanner/printer to one or more users.  The scanner works with Windows Paint software for all three nicknames.

    HP response is that some user control prevents the scanner software, who used to work on all three nicknames on the computer, which now works on one or more of the users.  They couldn't tell me which user control need changing.

    The HP solution is to restore my system when I could scan for all users of three.   I don't want to do that.   Does anyone have a better solution?

    The real problem is HP error messages.   When I click on scan a document, there is no answer.  Nothing happened.

    Then I tried to scan using Windows Fax and Scan.   I got an error message which helped me locate the source of the error.   I was able to fix the problem without creating a new user account.  I had deleted bu error the file MY Document.   Restore this file fixes the problem.

  • Script not running task for all objects using the Get-Content cmdlet

    Hello

    For some reason when I run the code following the newspaper bundles are only being dumped for the first host in the hosts.txt file. I have a script that gets the bundles of paper for all hosts in a cluster and rename the cryptic file name to reflect the name of the host with good Luc. I could just use the script to get the beams to all hosts in the cluster, but there are times where I need just one or two hosts in the cluster. Can someone tell me what is the problem with the code below?

    $VC = Read-Host "Enter name vCenter.
    $varHost = get-Content "S:\Get-Logs\hosts.txt".

    ##Connect to VCenter
    SE connect-VIServer $VC - WarningAction SilentlyContinue
    #----------------------------------------------------


    {foreach ($ESX to $varHost)

    $destPath = 'S:\Get-Logs\Logs\$($ESX) ".

    If ((New-Item-chemin $destPath-ItemType répertoire-ErrorAction SilentlyContinue) - eq $null)
    {- New - path $destPath - directory - ErrorAction SilentlyContinue ItemType}

    Get - Log - VMHost $ESX - Bundle - DestinationPath $destPath


    }


    # Disconnect - VIServer
    Disconnect-VIServer *-confirm: $false
    The Script ##End

    Although it would be ideal for the log files should be renamed at this point I would be happy if the script would create a folder for each host listed in the text file and place the log file in each folder.

    Thank you

    The variable $ESX contains only a string, not a Name property.
