    I'm definitely new and I need some help. I've moved into an apartment complex that offers free wifi, but I'm having issues. The signal strength varies from full bars to no bars within seconds, I'm frequently kicked off, and all internet connections are super slow. :mad: I have no access to the wireless router that my complex uses, but I'd like to know what I could do to fix these problems, if anything. Please keep in mind that I'm DEFINITELY a beginner and may not know what you're talking about if one was to throw out technical information. :p

    maybe a problem with the wireless router - are other people having a problem
    do you have more than one wireless device to see if its just your PC ?
    do you have a friend that has a wireless laptop that could try

    run xirrus and see what happens on the graph - anything below -70 (note the negative number) will be a poor or no connection

    ------------------------------------------------------------------------
    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/

    I'm not acquainted with any of my neighbors yet, but a friend of mine brought their computer over and the connection was still slow.

    I've run the iStumbler and attached are the results (hopefully). The network that I can connect to is highlighted in gray.

    I'm not sure what the 42% signal means, but doubt that it is strong enough for a reliable connection. Try moving around--immediately in front of windows, different rooms, the hallway, even outside--to see if you can get a strong signal. If you can, how is your computer's performance then? Hoping you have a laptop, 'cause if it is a desktop you are probably going to throw it at me for making that suggestion. :)

    Knowing if your computer plays nice with the network if the signal is stronger, and where that signal is stronger, should give us some hints about what can reasonably be done.

    I do not have any mac kit, so have not tested myself, however this product http://www.chimoosoft.com/products/apgrapher/ allows you to graph the wireless signal and monitor performance - this would help with TerryNet suggestion when looking for the strongest signal - you will also be able to monitor if it disappears or reduces in strength
