    I recently purchased a Etekcity Dual Band USB adapter (5G capability) to use in place of the internal 2.4 wireless adapter. The drivers installed successfully with no problem. All is well with the internal wireless card. When I disable the internal wireless card to search for wireless networks with the USB adapter, it states no networks are in range. I have full connectivity with the internal wireless card. The USB adapter does not show in ipconfig /all regardless of if I boot normally or boot in safe mode with networking. I am using Windows 7 Home Premium Service Pack 1. I have connected the USB adapter to another computer and confirmed the adapter is working correctly. The laptop is a HP Pavilion dv7 64 bit OS. Does anyone have any ideas?

    What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, kaspersky or Mcafee or any free security suites like zonealarm, AVG , Webroot etc

    do a TCP/IP reset

    ------------------------------------------------------------------------
    ------------------------------------------------------------------------
    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 to the faulty PC and install the program.
    You will now need to take a screen shot and copy that back to the working PC and attach the screen shot in a reply on the forum here.

    If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply

    http://go.pardot.com/l/66982/2015-01-26/2361i
    enter you details
    Download this file "DOWNLOAD WI-FI INSPECTOR Vx.xx "
    ( the site now appears to allow webbased emails like gmail, hotmail, outlook and yahoo now )

    There is also a xirrus gadget, But that does not have all the fuctionality "DOWNLOAD GADGET Vx.xx

    Alternative links - Use the links below
    Do NOT use any of the download managers offered - Cnet , just use the direct link below - and click on the download button
    http://www.softpedia.com/get/Network-Tools/Network-Monitoring/Xirrus-Wi-Fi-Inspector.shtml
    http://download.cnet.com/Xirrus-Wi-Fi-Inspector/3000-18508_4-75758254.html


    Then run and install the program - on a wireless enabled PC/Laptop
    if you get an error - You will need to have NET Framework installed for the WiFi Inspector to function.
    On windows 8 - (i do not have windows 8) but, it would appear that, When you first try to run, you may get a message that .net framework is needed, and included in that message is a link to download/install.

    Run the program

    A user guide is available here
    http://www.xirrus.com/cdn/pdf/xirruswifiinspectorguide1-2-0

    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.

    post which SSID name is yours, its located in the list, under network "Adapter Name" (1st column)


    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".
    note: the signal level is a negative number, so for example -88 is worst and -40 is better

    To post a screen shot of the active window.

    Windows XP
    Hold the Alt key and press the PrtScn key. Open the Windows PAINT application (Start> All Programs> Accessories> Paint) and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.

    Vista or Windows 7
    you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool
    http://www.bleepingcomputer.com/tutorials/how-to-use-the-windows-snipping-tool/

    Windows 8 & 10
    you can use the snipping tool > Open Snipping Tool

    (From windows 10 - All Apps>Windows Accessories>Snipping Tool

    Results of the TCP/IP Reset:

    Microsoft Windows [Version 6.1.7601]
    Copyright (c) 2009 Microsoft Corporation. All rights reserved.

    C:\Windows\system32>netsh winsock reset catalog

    Sucessfully reset the Winsock Catalog.
    You must restart the computer in order to complete the reset.


    C:\Windows\system32>netsh int ipv4 reset reset.log
    Reseting Global, OK!
    Reseting Interface, OK!
    Reseting Unicast Address, OK!
    Reseting Route, OK!
    Restart the computer to complete this action.


    C:\Windows\system32>netsh int ipv6 reset reset.log
    Reseting Interface, OK!
    Restart the computer to complete this action.


    C:\Windows\system32>

    I also posted the requested screen shot of Xirrus. Also, I attempted to uninstall the current wireless adapter in order to make sure there was no conflict with it. The issue remained with the wireless adapter uninstalled. When I reinstalled the drivers for the internal card, it is now doing the same thing as the USB adapter.

    Also, I forgot to add I'm using AVG Antivirus and ZoneAlarm Firewall software. I have attempted to connect using Safe Mode which disables these and still had the same problem, just FYI.

    I was able to find and fix the problem. Each time I attempted to get it to work, I had closed ZoneAlarm and disabled AVG. I decided to uninstall ZoneAlarm since I could re-install it easily. Once I uninstalled it and restarted the laptop, it was able to find all the networks around me and I had no issues connecting to my network. The problem is resolved.
