    Hi, I'm visiting a friend. Her wireless stopped working just before I got here. At first her wireless network wasn't showing up on my computer either, but after a few cycles of powering down and back up I was able to connect, so the router is working (she has cable modem and separate wireless router).

    Then I took a look at her computer. If I connect directly to the cable modem all works fine. But with the wireless router hooked up, I don't see her network on her computer. In fact, I don't see the numerous other networks I see on my computer. I have a list of about 15-20 networks on my computer, almost all of them secured. On her computer I only see about 5 networks, all of them unsecured and none of them actually work.

    Any ideas on what's going on here? Things I can try?

    We are both running XP. Let me know what other info you need. Thanks for any help on this.

    what type of adapter does it have - hows the aerial
    Is this a Laptop or desktop - maybe changing the position of the aerial may help - at least try that first as a test with xirrus

    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

    http://www.xirrus.com/library/wifitools.php
    Then run the program
    if you get an error - You need NET Framework installed for the WiFi Inspector to function.

    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.

    brilliant! It was the wireless switch. I'd never seen a physical switch before. She must have inadvertently hit the switch and disabled it.

    Anyway, it's working now! Thanks so much for your help!
