Lenovo G780 WiFi not detecting Wireless

This is driving me mad!
I have a G780 that I have re-imaged with Win 7 Enterprise x64 and reinstaled all the drivers for.
I am trying to connect to our wifi but the laptop is saying no connections detected.  I know the wifi is working as I have 40-50 other laptops connecting to it. 
The wifi is Broadcomm 6.20.55.51.
I have uninstalled and re-installed the driver, disabled and re-enabled in the BIOS, rolled back to the previous version of the driver (5.100.82.112), replaced the wifi card with another G780 wifi card.
The oiginal OS was Win 7 Home Premium x64 and was working then.
Any help will be greatly appreciated!
Solved!

hi taftus,
Welcome to Lenovo Community Forums!
Im thinking about the Software Controller of the Wireless
    Can you try installing this software to Enable the function
    Lenovo Energy Management Software 7.0
After Installation try Pressing FN+F5 to open the Wireless Radio Interface and makesure that the WIFI is on "ON"Status

  • Can not detect wireless card

    WRE54G / Win XP SR2
    My laptop and PDA can connect to the network wirelessly with no problems.
    Trying to connect my WRE54G to my network. On every attempt at AutoConfigure nothing happens. Have disabled router security and 'SPI Firewall' (whatever that is). Still nothing. Have disabled router security and 'SPI Firewall' (whatever that is), and McAfee Firewall. Still nothing. I have moved the WRE54G to within ~4 feet of the router and tried everything again. Still nothing.
    I have tried Setup but when I hit 'Next' I get the popup "Can not detect wireless card."
    Have tried a reset and have unplugged/replugged the WRE54G. FWIW, the WRE54G 'Link' light blinks blue once for about a second and turns a constant red. The 'Activity' light blinks blue twice quickly about every 5 seconds. Nothing on my PC shows any response.
    What is the wireless card that can't be found? The WRE54G?
    How do I resolve this?

    this worked for me too.  Although I was never able to use the cisco install wizard successfully.  I am using WEP security on my access point.  I took the following steps.
    1.  From laptop, connect to network wirelessly with WEP security settings in place
    2.  From laptop, open browser, go to: 192.168.1.1, select wireless security, disable wireless security
    3.  From Range Extender, hold auto-configure button.  It took me multiple attempts (~5) and it connected so the 'Link' light changed from red to a consistent blue.
    4.  From laptop, disable security for the access point (via control panel, wireless network connection settings)
    5.  From laptop, connect to wireless access point (via control panel, wireless network connection settings).  test internet connection.  Internet should work.
    6.  From laptop, access range extender web utility.  open browser, got to 192.168.1.240, enable security, input desired WEP security settings/passphrase. 
    7.  From laptop, enable wireless security for the access point.  from browser, go to 192.168.1.1, select wireless security and enable it.  use the same settings from step 6 (from the range extender).
    8.  From laptop, update wireless adapter settings to connect using the same security settings (eg. passphrase) from step 6/7.
    range extender, access point and wireless adapter/laptop should all be connected.

  • My apple tv does not detect wireless router sitting next to it

    I have my Apple TV sitting just few feet away from my router.  It does not detect my router.  So I added the IP addresses manually.  Under Apple TV Network settings, it still says Ethernet.  What can I do to get AppleTV to detect my Wireless rouer?

    Did you unplug the ethernet from AppleTv not just the router? I've found even a non-terminated cable plugged in disables wifi.
    Daft as it sounds, sometimes if the router is too close it can cause communication issues over wifi.
    If ethernet was working, why change to wifi?
    Can you confirm ethernet does still work and that AppleTV is not just 'stuck' in ethernet mode.
    Unplugging was a good test as that often corrects issues.
    It is possible your AppleTV software is somehow corrupted - restore via itunes using microUSB to eliminate that possibility, or that AppleTV hardware has failed and is 'stuck' thinking ethernet is connected.

  • Wifi not detected on my HP Pavilion g6 Notebook PC

    Product name :HP Pavilion g6 Notebook PCProduct no.: D4B10PA#ACJOperating system: Windows 8.1 64-bit version Hi,My PC does not detect my wireless connection.  All other deviced like my iphone, ipad etc do, so I know that the router is fine.also, I can see other networks near my vicinity but for some reason MY home network is not detected by my PC!My OS is up to date, so is my wireless adapter. I am using this forum by connecting to the internet by LAN cable. Please Please Please help me! Thanks,MS 

    Hi ,  Thank you for your query.   I grasp that your notebook does not find your network but does find others.  Your wireless drivers are up to date  as well as your OS. First what frequency is your network set to.  If you have it set on 5.0 GHz  please try changing it to either mixed mode or 2.4 GHz as that is the one the notebook works best on. Can you connect to a different network or hotspot? Have you ran the Windows troubleshooter? Have you ran the  HP Support Assistant ?
     Here is a link to HP PCs - Troubleshooting Wireless Network and Internet (Windows 8)that will provide more steps to try.   To show appreciation for my replying please click the thumbs up icon below.If this resolved your issue, please tell people by choosing solution provided.   Best of Luck!

  • X200 not detecting wireless networks

    Hello, 
    I have a ThinkPad X200 running windows XP, with an Intel Wifi Link 5100 AGN network card.
    It used to be working great, but about 3 weeks ago it stopped detecting wireless networks. 
    Since then it states: "No wireless networks were found in range."
    There are wireless networks around, this has been confirmed by using other computers. In fact, the laptop used to connect just fine. Just seemed to go out one day.
    The driver appears to be the newest one, (1/22/2012). 
    And looking in the support, the "allow the computer to turn of this device to save power" button is unchecked.
    It has been repaired and uninstalled. And seems to think the device is working properly.
    The only thing i think is that the receiver on the card is broken somehow and needs to be replaced.
    Any ideas would be very much appreciated! Thanks!

  • Satellite 5200-903 does not detect Wireless Adapter

    hello everybody,
    I wonder if anyone can tip me on this one...
    Since I reinstalled the OS ( have XP pro SP2 ) PC seems not detecting anymore the WIRELESS adapter in Device manager under Network Adapter.
    Also the light of the wireless switcher does not turn on anymore.
    I am also having problems to access the BIOS to check if the adapter is detected there, I do not have a Toshiba HW setup in Control Panel as indicated in the manual.
    Any suggestions?

    Hello Juliana
    The question is how did you install the OS? If you use recovery CD all tools will be installed including Toshiba HW setup. If the unit is preinstalled with Microsoft WXP CD you must install all Toshiba stuff belatedly.
    Just short explanation about WLAN card. Basically if the light of the wireless switcher does not turn on thats clearly indicate onto hardware problem. I assume that the WLAN card is defective. Check also if the card is listed in device manager.
    If you want to enter BIOS settings pres ESC button at the boot up procedure and keep it down for a few seconds.
    Bye

  • 15-n268sa wifi not detecting 5ghz

    I bought the 15-n268sa laptop, however when I try to detect 5ghz networks, it is not showing. I couldnt find bluetooth, thought it was a minimum requirement in the age we are in, however not complaining about bluetooth, since it was a miss from my end. I would expect at least the wifi to detect 5ghz networks. it is limiting my speed badly.
    This question was solved.

    Hi,
    It only has "802.11b/g/n (1x1)" as shown:
       http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c04072736
    therefore it can't "see" 5GHz network and the chance to change it is VERY slim.

  • Lenovo R61i Not detecting wireless!!​!

    Bought my gf a new computer for Christmas and pulled out her old Lenovo yesterday to see about using it for myself.  It was ungodly slow and loaded down with music so I did a factory reset on it and when it was done I couldn't pick up ANY wireless connections...I am lost...please help...

    Hi.
    These are your original factory specs:
    ThinkPad R61i (7732-8AU)            
    T2330(1.60GHz), 1GB RAM, 120GB 5400rpm HD, 14.1in 1280x768, Intel X3100, CDRW/DVDRW, Intel 802.11abg wireless, Bluetooth, Modem, 1Gb Ethernet, UltraNav, Secure chip, Fingerprint reader, 4c Li-Ion, WinXP Pro
    Notice that you have an Intel wireless card. Unless your wifi card has been switched, your wireless LAN (wifi) adapter should be Intel PRO/Wireless 3945ABG, as confirmed by System service parts - ThinkPad R61, R61i, and T61 (14.1-inch widescreen). If you suspect the wifi card has been switched, is not connected properly, damaged or was removed, it just takes 2 minutes to check by removing the keyboard as shown in the Lenovo training movie here:
    Hardware Removal & Installation Movie Index - Notebooks
    Hardware removal and installation index - ThinkPad R61
    And here is your Hardware Maintenance Manual - ThinkPad R61, R61i, T61 14.1-inch widescreen
    The correct wireless driver can be found by entering your 7-digit type/model number in the Lenovo Drivers and Software download page. This will provide you with a list of machine-specific drivers. Choose "Intel Wireless LAN (abgn, abg, bg) for Windows XP - ThinkPad" (filename "6mwc24ww.exe") in the "Networking: Wireless LAN" section. Direct link here.
    After downloading and running the file, it should extract to the following (default) directory:  C:\DRIVERS\WIN\WLANINT. Choose to "Install Intel wireless LAN now" and reboot. That's it, you're done.
    Otherwise, to complete the installation process later, navigate to the appropriate folder where the files were extracted. (In this case, Click "Computer"---> drive C---> DRIVERS ---> WIN---> WLANINT and then double-click "AUTORUN.EXE").
    Reboot and you should see wireless networks within range. If not, make sure wireless is turned on in BIOS menu (Hit "F1" at the Thinkpad splash screen when first powering up the computer). Also check that the physical wireless switch towards the bottom left side of your palmrest is turned on and that "F5" wireless radio options are on. (To utilize Function key "F5" options you must first install Lenovo Power Management driver from the "Power Management" section and Hotkey Features Integration from the "Software and Utility" section).
    If you have any other missing drivers you may browse the general list of R61/R61i drivers here: http://support.lenovo.com/en_US/research/hints-or-​tips/detail.page?&DocID=HT037648 
    P.S. I have given very detailed instructions so others besides yourself may be helped and begin learning how to navigate the Lenovo driver matrix successfully. If you have been helped by this post, don't forget to say "Thank you" by clicking the *STAR* on the left and marking this as the "Accepted solution" so others may reference this post in the future and be helped
    Have a great day. (I do not work for Lenovo)
