    Hi, I run a couple of laptops at home on wireless Sky router. Work laptop runs fine but this one (Acer Aspire 8930 with Windows Vista home premium, sorry) drops out occasionally for a minute or two, never detected a pattern. Has done it since new a couple of years ago and now decided to do something about it. Seen various other posts ask for ipconfig/all so here it is. Obviously this is when it's working! Any help greatly appreciated.
    Cheers.

    would you post the following tests when its working OK and then repeat ALL the tests when it disconnects and make sure you also tells which tests posted are for what condition

    Please post back here the make and exact model of the router and if separate, the make and exact model of the modem

    ------------------------------------------------------------------------
    ipconfig /all
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

    We would like to see the results from ipconfig /all post back the results in a reply here

    Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

    In the command prompt window that opens, type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    ipconfig /all > network.txt & network.txt

    It will export the results to notepad and then automatically open notepad.

    Now all you need to do is copy and paste those results to a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will be highlighted
    Next
    From the notepad menu - choose Edit - Copy
    Now go back to the forum - reply and then right click in the reply box and paste
    ------------------------------------------------------------------------

    Ping Tests
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

    Start> Run {search bar in Vista/W7}> CMD to open a DOS window and type:

    Type the following command
    Ping {plus the number thats shown against the default gateway shown in above ipconfig /all}
    Post back the results
    rightclick in the box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    Type the following command
    Ping google.com
    Post back the results
    rightclick in the box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    Type the following command
    Ping 209.183.226.152
    post back results

    Run Xirrus Wi-Fi Inspector
    Download and install

    If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.


    http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
    Direct link to the program is here http://wpc.475a.edgecastcdn.net/00475A/XirrusWiFiInspectorSetup.1.2.0.exe

    {If the above link does not work heres another link http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html}

    Then run and install the program - on a wireless enabled PC/Laptop
    if you get an error - You need NET Framework installed for the WiFi Inspector to function.

    Run the program

    A user guide is available here http://www.xirrus.com/Products/Wi-Fi-Inspector/xirruswifiinspectorguide1-2-0.aspx

    post a screen shot of the program running - if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information, and also post which network "Adapter Name" (1st column) is yours on the list

    To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
    To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.
    Full details are here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot

    Note:
    For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better.

    If you are using the Mac OS then use http://www.istumbler.net/

    Hi etaf, thanks for the prompt response. Wireless router is a Sagem supplied by Sky, no other model number on there I'm afraid. Posting test results for when it is WORKING below. Had already put up ipconfig but will do again. Disconnection is usually a matter of 20-30 secs so I'll try to see if I can batch it. Last time I did this was on an autoexec file to put childish messages on a colleague's PC in 1989 so any tips welcome!

    Would you believe while trying to upload screenshot of wifi inspector I got a drop out. Therefore taken fresh screenshot and can clearly see dip in signal at around 50secs ago.

    Will post again if I manage to do all these while connection dropped.
    Cheers,
    Richard

    Make sure you have the latest wireless driver from the PC manufacturer's web site.

    Do you get signal drops like that with another computer (or another wireless adapter)?

    OK, will do but tend to have shockers with drivers in the past. Badly broke previous PC when trying to upgrade video drivers! Drop outs only appear on this laptop. I work all day with no problems on work laptop. Thanks.

    Does that mean that when you see one of those big signal dips in strength on one PC the other one shows a steady signal level? I assume that's what you mean, but want to make sure.

    I haven't installed wifi inspector on my work laptop so I can't explicitly say it doesn't get signal drops but certainly I don't get any dropouts and the network tray doesn't change status like it does on home.

    Ok, I've gone into Device Manager, done update driver on the driver tab for Inter(R) Wireless WiFi Link 5100, selected search automatically for updated driver software and it tells me windows has determined it's up to date. Is this good enough or should I double check what Windows is telling me?

    If you are satisfied with the wireless performance just leave well enough alone. If you are unsatisfied with the wireless performance "Make sure you have the latest wireless driver from the PC manufacturer's web site." :) Most times the driver is "buried" in a self-extracting self-installing executable or maybe a .zip file and Windows will not find it.

    Ok, done that. had the same version number as the one I had but a later date. Unlike several of my previous experiences with driver updates the device still seems to be working. Will keep my eye on the monitor to see if it still drops out. Also monitoring the reception of my next door neighbours' wifi. If that drops out as well presume that proves the problem is local to my pc and not the router?

    The typical scenario is that Intel will update the driver and make it available on their web site with the caution that the motherboard or PC manufacturer may modify it to work in their system. That's the one that Windows finds. If the PC manufacturer modifies it usually the version number will be the same as Intel assigned but the date will be later.

    I would make the same presumption. :)

    Driver updates can be tricky. I usually do not update them unless I have an issue, and when I do ...

    This is my preferred order for finding drivers:

    1. PC manufacturer's web site,
    2. Motherboard manufacturer's web site,
    3. Device manufacturer's web site,
    4. A "drivers" site, such as DriverGuide,
    5. Anywhere you can find one that might work,
    6. Let Device Manager try to find one.
    7. Use Windows Update.

    (4 through 7 are really tied, and with Windows 7 the Windows Update should be at least 4th. The main message is that the first three are almost always to be preferred.)
