    Hello,
    I am having trouble getting the built-in wireless adapter on this laptop to get connected to the internet. I have installed the following driver:
    http://support.lenovo.com/us/en/downloads/migr-73611
    but have had no luck. there are no available wireless connections I can connect to.
    I have also tried to use USB wireless adapter TP-LINK TL-WN725N to connect to internet. It is able to find available connections but when it tries to connect it says unable to connect and give options to troubleshoot. Once troubleshoot is complete it says to investigate router or access point issues. I have reset the router many times. Other devices are working fine with the internet just not this laptop.
    I am running windows 7 64Bit.
    Please help.
    Thanks

    Can you connect the laptop to the router using a cable at all ?

    using just the laptop wireless adapter
    unlikely to be this as it is reporting NO networks available - but check anyway please
    Check the wireless is switched ON
    theres often a physical switch or a combination of the FN and one of the F keys to toggle the wireless on/off
    often F2 is used - but note , not always - look for a symbol that looks a little like (( i ))

    is the wireless on?

    can we see an ipconfig /all - see how below

    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
