Lenovo IdeaPad Flex15 WiFi not working

IdeaPad Flex 15. Changed drivers to the latest from Intel. 17.1.0.19 from 7/21/2014 and the system always drop down in a few mins. I changed the power settings so fixed the issue with sleep mode. (when close laptop, and oipen, the card was not working anymore until manual disable/enable device).
Now it works, but lost connection and need to be at least switched off and on to reconnect network.
I want a quick solution please or take the laptop back and give me more mone. I'm not able to continuously work with that device and it is pain to have it. I just feel it was really bad investment into this device.. and to know that before, never will buy it.

hi oxley
Sorry to hear about your Wi-FI trouble.
If you have the Intel® Wireless-N 7260 (Single Band, Wi-Fi + Bluetooth) combo card, can you try the following:
1. Install Version: 17.0.6 (Latest) from the Intel site:
File name: Wireless_17.0.6_De164.exe
Version: 17.0.6 (Latest)
Date: 08/11/2014
Size: 21.35 MB
Language: English
Operating Systems: Windows 8.1, 64-bit*
2. Disable the Bluetooth (see this guide)
3. Set the power management settings of the Wireless Card and the PC to High Performance (see Method 2 and 3 of this guide)
When done, do a continuous ping via the command prompt (eg. ping -t www.google.com) and observe. If you get continuous reply and no connection drop / request timed out then that means the Wi-Fi connection is stable.

  • Lenovo Ideapad U410: Display not working after sleep and/or restart

    Hello all,
    I am recently having some inconsistent display issues with my Lenovo U410 laptop i7 1TB with a Windows 8 PRO upgrade (came with windows 7). 
    When I press the Power Button on my laptop to put it to sleep, the Screen turns black as if it is off, but the Power & Battery LEDs on the front of the laptop remain on, as well as the LED on the power button.  However, when I try to wake my laptop, there is no response on the screen (remaining black as if it is off).  The internal fan is running, however I receive no feedback when "blindly" trying to input my password.
    I've tried to turn the power off and back on to no avail.  I've also removed the power source and held the power button for a couple of seconds and that did not solve the issue either. I've tried connecting the laptop to a screen via HDMI (since there is no other AV port on the device), but there was no signal being sent through. 
    This is an inconsistent issue that began yesterday 6/11/2013.  When the laptop is left alone for a little and is turned on again, the display works, but after closing the lid (sleep) or pressing the button, the display fails to turn on upon awakening.
    In most recent circumstances, Today (6/12/2013) I was installing a Windows update that required my computer to restart.  When the update configured perfectly BEFORE it was restarting, but AFTER the restart, my internal fan began to work, but the display was not on.
    Does anybody or Tech support know what may cause this inconsistent behavior?  or know any solutions to this issue?

    I am facing similar problem - post sleep & sometimes on touchpad event - the screen gets stuck & a strange array of gray screen comes or the existing screen's colors get distorted & the laptop gets stuck. 
    model - Lenovo U410; 64 Bit; Windows 7 Home basic;,  Intel core i5 processor 
    I have upgraded display drivers but that hasn't changed anything. Any help is appreciated.

  • How to fix iphone 4s wifi not working

    How to fix wifi not working on iphone 4s after it is updated to ios 7 ?
    Here is what fixed my wife's phone after several weeks of no wifi. We had removed the Sims card and transferred to another phone which was running ios 6. My son was visiting and said Apple had come out with an update a few days ago and he decided to attempt to install it on the 4s phone that had no wifi and no cellular because the sims card was removed. He tapped the icon to update the new ios version and received the message to the effect that No WiFi available would you like to search for available networks. He selected yes and immediately the wifi came on and has been working now for two days. Also we never installed the update to the new ios.
    My advice is to remove your sims card like we did or trun off your cellular and attempt the update to see if you get the message to search for available networks and then of course choose yes. Go figure. Hope this works for you.

    Hey there. You didnt state what operating system you are using but I was able to find two articles that should help resolve your issue. 
    Troubleshooting Your Wireless Network and Internet Connection (Windows 7)
    Fixing Bluetooth Issues
    These articles will go through all the basic troubleshooting steps. Let me know if this helps resolve the issue at all.
    Thanks!

  • Iphone 3G wifi not working after upgrade

    Iphone 3G wifi not working after software upgrade, no proper fix from Apple. APPLE SUPPORT - R U SLEEPING.......

    You are not talking to Apple. This is a user to user forum.
    If you're using the iPhone 3G, there will be no fix for your problem. The software you have, 4.2.1, is the end of the line for the 3G. Apple is no longer providing software updates for the 3G.

  • Lenovo b590 power management not working

    Hello! I have a problem with my laptop, a lenovo b590. (pentium 2020m, 4gb ram, intel hd graphics): the Lenovo Power Management driver not working.... 
    Is exactly the same as here, but, the only difference is that I use windows 8.1: 
    https://forums.lenovo.com/t5/Lenovo-3000-and-Essential/Lenovo-B590-Lenovo-Power-Management-driver-no...
    As no one could solve the problem there, I thought it may be more visible now and someone can help me
    So, how can I solve this problem?
    Edit: I tried everything that was said there, to no avail ...
    Sorry for my english..

    i'm not sure if there's any suitable cooling pads for your computer but cleaning the fan could be another solution. it may work but it may also void your warranty.
    due to it's probably hardware issue, at this point i don't think i have much suggestions for you.

  • Network controller& USB controller driver not found and wifi not working

    hello  I Purchased HP 15-ac025TX (M9V00PA) Notebook laptop  .  i have installed all driver from HP site here is the link  http://support.hp.com/in-en/drivers/selfservice/HP-15-Notebook-PC-series/7771404/model/8326084#Z7_3054ICK0KGTE30AQO5O3KA30R1  but still netwok controller driver not found also wifi not  working  i installed blutooth drivers too . I am using window 7 sp1 (32 bit) For network controller device ID is PCI\VEN_14E4&DEV_4365&SUBSYS_804A103C&REV_01 secondly  univeral serial bus driver(usb) controller   not found i installed all drivers from above link  also update windows  but still no solution hardware id of usb controller is PCI\VEN_8086&DEV_9CB1@SUBSYS_80C2103C&REV_03  and last i am unable to download  AMD/Intel Switchable High-Definition (HD) Graphics Driver. the download link not working KINDLY RESOLVE THE ISSUE THANK YOU    

    Update: While the driver I knew would work has not shown up yet, I did some detective work and explored some other broadcom wireless card driver folders from some HP links, and I found one that should work for you. While it says it is for HP desktop PC's, they put the exact same wireless card form factor in a desktop PC that they do in a notebook PC. I see no reason why this driver would not work, since the setup information file contains the same hardware ID that you posted.  Here is a partial copy and paste of the driver setup information file and you can see the hardware ID you posted is supported by this driver.  x86 - Win7
    [BROADCOM.NTx86.6.1]
        %BCM430N_DeviceDesc% = BCM43XNG_NT61, PCI\VEN_14E4&DEV_4365&SUBSYS_2230103C

  • Hi, i am not able to connect to the internet. wifi not working.

    hi, i am not able to connect to the internet. wifi not working. not able to find proper drivers for 32 bit win.7 os. need urgent help..
    This question was solved.
    View Solution.

    Hi:
    I can give you the link to the wifi driver, if you do the following steps to post the hardware ID for the wireless card, so I can figure out what model wireless card the notebook has...
    To find the hardware ID, go to the device manager and click on the device labeled Network Controller.
    Then click on the Details tab at the top of the Network Controller window.
    Now you see a Property drop down list and it is defaulted to Device Description.
    Drop down on that list and select the second item (Hardware ID's).
    Post the top string of characters you see in the window.

  • TS1398 Iphone 5 Wifi not working

    Hi Apple .
         My wifi not working ...i have already try reset network it seem the same .... sometime i only able to use for few hours after that my wifi not working anymore and sometime event i have to shut down my iphone for wifi connection . Now it become more worst sometime i unable to turn on my wifi .... pls email me for solution . I purchase my iphone from Apple Store online from malaysia but currently im working at oversea . Can i get warranty at Taiwan ?

    The iPhone warranty is not international.  Apple will only honor the warranty in the country where the iPhone was sold.
    If your WiFi connections button in Settings is greyed out, see http://support.apple.com/kb/TS1559 and if you want to Troubleshoot, and can access the router, http://support.apple.com/kb/TS1398 those may help but you probably need to have the iPhone tested by an Apple technician.

    If you tried all that is in the support doc where you posted your query and it did not resolve the issue, it is a hardware failure. Seek an appointment at the genius bar for evaluation.

    Hi All,
    Two issues I faced, Wifi not working and Mobile Hotspot giving message 'Regulations in country doesn't allow'. Here what I did to resolve and make it work:
    - Change the Timezone to Alaska or some other country and then try the hotspot, it should work
    - Shutdown the device and start after 30 Seconds (PS restart as part of OS upgrade is not complete), suggestion is to have a clean reboot of the device after upgrade
    - Revert back to old Timezone post restart
    It worked for me. I will monitor for couple of days and then post any more update.
