Wifi not work in windows 7 in compaq persario CQ40-601tu

hi...
when i installed windwos xp then there is a wifi hardware shows in device manager..but when i install windows 7 then wifi stop working..!!
plz help..!!
reply fast...

Hi:
Please do the following steps and I will post the link to the wifi driver you need...
Go to the device manager and click on the Network Controller needing drivers.
You should see the Network Controller device listed under an Other Devices category.
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.
If you do not see a Network Controller device, install this software and use it to turn on the wireless card and then see if there is a network controller device.

Wifi not working under windows 8.1 with Bootcamp

Hi, I have installed windows 8.1 under bootcamp. it seems to work fine however the wifi connaction is not existing under windows. therefore i can only connect via ethernet. Anyone an idea how to solve it? Thx

Hey there,
I don't know if it's still interesting for you, but I've had the exact same issues. The only solution, as far as there is no official change from Apple, you can install Windows 8.0 via Bootcamp with official drivers for Bootcamp (wifi works great) and then install the upgrade to 8.1 as Windows still uses the former installed drivers from Win 8 on 8.1 as well.
Hope that helped, 8.1 runs even better on my MB Air than Mac OS 10.9 :/

Wifi not working with Windows Vista - BT in denial

I run a laptop repair centre in Dundee and have BT Business Broadband which was working fine until a few days ago.
Now, any vista machine refuses to connect to the wifi while XP and Windows 7 are unaffected.
I have hundreds of laptops in stock at any one time and this issue is affecting them every single machine installed with Vista. These same machines work fine when connected to another wifi service (virgin media).
I phoned to report this fault and have been told that it's not BTs problem and I'd have to pay to have someone come and look at it. I was put through to a supervisor who told me that it "was Bill Gate's fault"!!!!!
I've worked with Vista for the 7 or so years it's been out and know the operating system inside out.
This is NOT a fault with the machines, or Vista, this is definitely a router fault but the supervisor refuses to believe this.
I'm now trying to cancel my contract as I'm not receiving a full service.
This is absolutely unbelievable that such a major company can just brush me aside and deny there's any fault. They won't even entertain the idea of sending me another router to try!
Has anyone else had this problem?

After phoning the same number, this time I got someone very helpful who knew their job well.
Apparently there is a known issue affecting certain routers at the moment. This problem causes connection issues with Vista machines on wifi and the fix is to reduce the encryption from WPA to WEP.
This works perfectly.
The person then explained that they were expecting a firmware update to be released soon for the routers which should cure the problem properly.
Why in **bleep** did the person this morning not know that, and even worse, why didn't his supervisor that I demanded to talk to not know that either. He point blank refused to even consider the notion that the fault lay with BT!
Some staff need retrained not only on the technical aspect of their job but how to deal with customers as well....
Thanks for the help folks

A665-S5170 WiFi Not Working After Windows 7 32 Bit Install

I had to put a new hard drive in my A665-S5170. Since there were drivers listed for Windows 7 32 bit for this computer, I installed a copy of Windows 7 Ultimate 32 bit that I owned. After installing every driver listed, I have no wifi. Another forum I was reading suggested it was because someone with the identical problem had not installed a driver for their chipset, and there is no chipset driver listed, but there is one for the 64 bit version.
When I look at Device Manager, I see the "!" by "network controller."
Any suggestions?

Downloads here.
It was apparently not intended to run 32-bit Windows on that model. But probably this driver works.
   Intel WiMax/WiFi for Windows 7 (32), 14.1.1.3.1

Wifi not working with windows

Hey guys,
My problem is quite odd. At my house, my wifi works fine on both partitions. However, when I'm at my friend's house, it works on my mac partition but not on windows. I tried figuring out the problem by myself, and I one thing I noticed is that it seems to be able to connect to wifis with WPA password but not anything else. But anyways yeah, help would be much appreciated.

Kim, a Restore point should have automatically been made by Windows BEFORE processing the update. You should run System Restore using that restore point and then HIDE that update so that it isn't ever installed again.

Anyone could help as captioned subject?

Give this a try: http://wikidrivers.com/wiki/BroadcomBCM43xx5.60.18.8
Once you get the driver extracted, install it manually by browsing to the directory where the extracted driver is and choose the *Broadcom 43224AG 802.11a/b/g/draft-n Wi-Fi Adapter*.

hi erabbath,
Welcome to the Forums.
If you have the Intel Centrino N2230 Wireless + Bluetooth adapter, can you try to:
1. Navigate to the Control Panel (large icon view) > Devices and Printers and try to pair a bluetooth device (i.e. Bluetooth Headset) and observe if it gets detected under the device list.
2. If the Bluetooth Headset is listed but it's not working try toright click on it > choose Properties. On the bluetooth properties Window, go to the Services Tab and check all the appropriate bluetooth services.
Sample picture
Let me know your findings.

Itunes wifi sync not working on windows 8!!

Does itunes wifi sync works on windows 8? Because i already have enabled wifi sunc but after i disconnect the cable from the ilhone it doesnt aloud me to do sync via wifi. Does anyone know how to make it work properly on windows 8?

Interesting. I still haven't had any problems with iTunes 10.7 under Windows 8 Pro, including adding music files purchased from a 3rd party source (Amazon) and buying an album through iTunes. iTunes successfully matched the Amazon-purchased MP3's, and I was able download the iTunes AAC's to replace them. The only thing not typical about my set-up that I can think of is that I have iTunes installed on my B: drive--both the program files and the iTunes Media folder--not on my C: drive (an SSD). My library sounds about the same size as yours (~4,000 songs).
(My only Windows 8 problem has been with DVD playback and the Windows 8 Store Netflix and Hulu apps. It looks like the new AMD graphics card drivers don't seem to be passing HDCP tests under Windows 8. There are simple work-arounds--watching Netflix or Hulu in a web browser--so at this point, I'm just waiting.)
Good luck with your iTunes issues.

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

This question was solved.

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.
