    I hope I'm posting this in the right category...
    In any case, to begin, I just want to let whoever reads this know that I am definitely not the most experienced tech guy out there. :p A technician is supposed to come Sunday morning to help try and figure out this problem, but I figured I'd post it here and see what kinds of responses I receive.

    A few days ago, I returned from a vacation to find that my old modem, a Motorola, had burnt out/died/lost power; I'm not sure. So we (my father and I) purchased through the recommendation of a Cox representative a relatively new 2 in 1 modem/router unit called the Gateway.

    The wired connection, which we use for the desktop, has been perfectly fine. My laptop on the other hand, which I use wirelessly, might as well have no connection at all. Initially, it had no problem connecting to the new unit. I brought up my homepage, which came up deceptively quick, and told the technician that all appeared to be working normally. However, after going through some other websites, I found that it was loading pages/videos EXTREMELY slowly. After a while I did a speedtest, and after many trials I'm finding my average download to be about 1 Mbps, and upload to either be higher (?) at about 1.4 Mbps or unreadable. It should be noted that with the package we have, we should be getting about 30 down and 3 up.

    My father and I talked with a couple Cox representatives on the phone, but they couldn't decipher the problem. There is only one thing that I could think of that might contribute to it, but it seems farfetched. My laptop was originally supposed to come with some piece of hardware that allowed it to connect to not only 2.4 GHz frequencies, but also 5 GHz frequencies emitted by the router or whatever it is that lets you connect to the Internet. It didn't come with it for whatever reason, and because of my limited knowledge, I thought this 5 GHz connection chip was a must have (which I now realize is not) and had it installed. The thought aroused by this was that could my computer be trying to connect to the Gateway on some sort of different frequency? I dont know exactly what else to think.

    Sorry for the long post, I tend to drone on a little bit...

    I don't know my laptop's specs, but I suppose I could find them out if needed.

    Thanks for anyone who can help!

    how many devices do you have that can connect wirelessly

    does the cable connection work at the correct download speed reliably

    can we see an xirrus screen shot - from a wireless PC

    ------------------------------------------------------------------------
    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://info.xirrus.com/Wi-FiInspectorConfirmation.html

    {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/cdn/pdf/Xirrus-Wi-Fi-inspectorguide-1-2-1-RevB-6.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 ("Go Advanced" button) and use the Manage Attachments button to upload it here.
    Full details are here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot

    Or if you are using Vista/Windows 7 you can use the "snipping tool" which is found in
    Start> All programs> Accessories> Snipping Tool

    Note:
    For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be green".

    If you are using the Mac OS then use http://www.istumbler.net/ or
    if you want to optimise base station position and signal strength / dead spots use
    http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal
