Portege Z830 - Wireless is not workng after Windows 7 update

Morning,
Two days ago I've installed a Windows 7 update from Qualcomm Atheros and my Wireless just died immediately after. This update is not on the list of updates and I cannot uninstall it.
Any solutions guys?
Help aprreciated in advance.
Thanks

Have you tried to roll back OS few days back before you have installed this update?
You can do this with system restore option.
I don't know if this will help but you can try it anyway.

Go to Solution.

Take not of the Wireless Settings(SSID and WEP/WPA Key) on your Router...
To know the Wireless Settings follow this link
Once you know the Wireless Settings attempt to connect to your Wireless Network...
XP :
Click on Start and goto the Control Panel and double click on Network Connections, right click on Wireless Network Connection and click on Properties.
Now on this window, click on the second tab Wireless Network and give a check mark on "Use windows to configure my wireless" and then remove all the network names present in the Preferred Networks Window. Then click on OK...
Right click on the Wireless Network Connection again and click on View Available Wireless Networks and try to re-connect to your network...
Now it will give you the opportunity to put the network/wep key, make sure you enter the correct network key and confirm it...
It will connect...
Vista :
Click Start >> Control Panel >> Network and Sharing Center >> Manage Wireless Networks, here remove all the networks present and close the Window...
Click on Connect to a Network and try to re-connect to your Network, it should ask for your Network Key/Password, enter the correct password/network key and click Connect...

HP Pavilion 15-n268sa will not boot after windows update (windows 8.1)

After a series of windows update (windows 8.1) my HP Pavilion 15-n268sa will not boot up, no fan noises, no lights no nothing.
I have tried a "hard reset" a number of times with no success.
When the battery is present the white LED flashes 3 times when the power button is pressed.
Please please help.

Hello Cuffy,
Welcome to the HP Forums!
I understand you notebook will not boot after a series of Windows updates.
Can you tell me if you are able to access the HP Recovery Manager by repeatedly tapping the F11 key while the notebook turns on? If you can access this, try doing a system restore to before you installed the updates. If not I would suggest you go through this document: Computer Does Not Start and the LEDs Blink or the Computer Beeps.
If it's the Caps Lock light that is blinking this document will tell you exactly what the error is (spoiler: 3 beeps is a memory failure). This could also explain the failed updates. The updates are stored in the RAM before being applied to the operating system.
You can try reseating the RAM, or using only 1 of the RAM cards, as you have 2x4GB cards. If it still doesn't work with 1 card, try the other card to confirm it has failed.
You can replace defective cards via HP Phone Support if covered under warranty or at the HP Part Store if not covered. You can contact HP Technical Support at 1-800-474-6836 in North America. For all other regions click here.
Hopefully this information helps!

Unable to connect to Office Wireless Network (802.1x) after Windows Update

Hi, my notebooks are on Windows 7 Enterprise 64bit. We have only recently started Windows Updates.
We are on a Wireless network 802.1x.
In the past, we are able to do the following steps :
1. Open the "connections are available" window by clicking on the wireless icon (signal bars with yellow sun)
2. Right click on the desired network and choose properties
3. Change settings (eg. MEAP or use local Windows credentials etc)
4. Click connect to connect
Now, from the "connections are available" window, when we right click on the desired Network, only "connect" is shown.
In this case, I cannot connect to the network as the settings are wrong, if I cannot connect to the network how do I change the settings ?
Please kindly advise

Hi,
I agree with britishdhez.
In addition, I would like to confirm which update caused this issue. Is it a driver update? I suggest installing driver update from the manufacturer's website.
You can also reinstall the wireless driver:
a. Click Start, type "devmgmt.msc" (without quotation marks) in the Search bar and press Enter.
b. Expand "Network adaptor".
c. Right click on your network card and then click Uninstall
d. Remove the driver software at the same time.
After that, restart the computer and reinstall the network card driver.
Meanwhile, you may run the Network troubleshooter to see if it can help diagnose and solve your problem:
Using the Network troubleshooter in Windows 7
http://windows.microsoft.com/en-sg/windows7/using-the-network-troubleshooter-in-windows-7
Also, please remove the wireless network profile for a test.
Delete a profile
At the command prompt ( Win+ R-->CMD ), type:
netsh wlan delete profile name="ProfileName"
For you reference: Netsh Commands for Wireless Local Area Network (wlan)

Plz help, "device not detected" after windows updates?? I have so

I have An Audigy 2 ZS, and have the latest drivers. It has been working PERFECT, LAST NIGHT I had like 0 WINDOWS UPDATES, i dont' know if any of these had anything to do with this. But, I just now went to the icon in the task bar, and went to change SPEAKER SETTINGS to switch to HEADPHONES as I ALWAYS DO, I was surprised when the "unable to change the sound device to your selected device", you press ok, and it comes up TWO MORE TIMES, Right after each other.
I DO HAVE SOUND, FOR NOW. I have read other mentioning this error, but I didn't seem to find any answers. I can't go to speaker settings, or Surround Mixer,
OK, NOW I tried to go to GRAPHICS EQ, and an error came up that said "THE AUDIO DEVICE SUPPORTED BY THIS APPLICATION IS NOT DETECTED, THE APPLICATION WILL EXIT"
What is going on?
I went to device manager and it says that the device is working properly, and I DO have sound.
I DON'T get it. And I'm not likeing this. This is starting to worry me.
Does ANYONE know what is going on.. PLZ?

Thanx for the reply. I just now fixed it. I'm not totally sure what I did. Earlier I had uninstalled the device from Device manager, and then restarted, and it installed the drivers from the CD. It didn't fix it. So, I ran the LIVE update here at creative.com and downloaded the version I had before, I guess because when i had ran the update before I uninstalled the device the update wasn't there.
But, it started to update, and said something it had to restart the pc in order to install the update, and after it installed the new "creative audio console" it now works.
the whole thing was strange since I dind't lose sound at all. Just couldn't access settings.

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.

Wireless trackpad not working after lion update on May 15, 2012

Right after OSX update on May 15, 2012, the pairing of my wireless trackpad to the desktop is no longer working.
First the bluetooth found my trackpad. After clicking "continue", the box showed: "No trackpad found The pariing attempt was unsuccessful, click "continue" to try again.
I've been trying for several times. Still not working!!

Yes, I did replaced a new set of batteries!! The computer keeps finding new wireless trackpad but once I click on continue, the box showed "the pairing was unsuccessful". Again, this happend when I updated my OSX this morning.
I clicked on the bluetooth set up box. It shows a green light (connected) but sometimes turned red (disconnected) for no reason. Then I clicked on "Monitor connection RSSI. As I played with the trackpad, there seemed to be signals being detected by the desktop.
Still, the mouse cursor cannot be moved by the wireless trackpad and the pairing is still unsuccessful.

Itunes not opening after Windows Update

I am aware that a post was made recently that was very similar to this one, but my problem is different enough that i deemed it necessary to make my own topic)
Ever since I downloaded the new Itunes 10, everytime I have had a Windows update (I am using Windows 7), Itunes will not open. When i double click it, the mouse shows the "loading" cursor but the program does not work. This has happened two times before, and each time i had to uninstall Itunes as well as Quicktime, and then re-install both of them.
I would like to be able to update Windows without Itunes dying on me, so are there any other ways to get it to work? Any help is very appreciated.

oh my gawd
Brallen91,
thank you so SO much for providing that link!
been stuck with that problem for days; tried uninstalling, removing, reinstalling, all the things. also deleted my preference files in ~/Library/Preferences/ like a thousand times etc.
all I missed was that there also are two files in ~/Library/Preferences/ByHost/ too; I deleted those, restarted; woosh, iTunes is finally back! *dances through the entire house*
thanks a ton man <3

Outlook 2013 does not open after Windows / updates

Hi,
I had installed Office 2013 on my Windows PC. I got updates for Office 2013 and after that my Outlook stoped working. It did not open except in safe mode. I checked similar problems and tried to remove add ins in safe mode but still does not work. Tried
to create new profile no success. Then I tried to re install it yesterday and it worked fine until I got updates again today and it stops open again.
Is something wrong with Office 2013 updates?
Any suggestion/solutions to fix this problem.
Chagi

Hi,
Since Outlook works fine in safe mode, you can also try to open Outlook with
/safe:1 and /safe:3 commands to narrow down the cause.
/safe:1 Starts Outlook with the Reading Pane off.
/safe:3 Both native and managed Component Object Model (COM) add-ins are turned off.
Please also try to open Outlook with /resetnavpane command to check if this issue is caused by corrupted Navigation Pane settings. To do this, press Windows key + R to open the Run command, type
outlook.exe /resetnavpane and press Enter.
If above not working, please try to use the Inbox Repair Tool to scan and repair your Outlook data file errors to check the result. See:
http://office.microsoft.com/en-in/outlook-help/repair-outlook-data-files-pst-and-ost-HA102749454.aspx?CTT=1
In addition, you can try to uninstall these updates to check if Outlook will work, so that we can determine if this issue is caused by released updates.

Access 2010: ListBox (Forms 2.0) not working after Windows Update

After one of the updates attached was installed the following VBA-Code line causes an error on Windows 7 using Access 2010:
Me.lbCountries.AddItem rst("Country")
lbCountries is a ListBox (Forms 2.0) using
class: Forms.ListBox.1
OLE: Microsoft Forms 2.0
MultiSelect: Multi
ListStyle: Option
The code is still working using Win8 (x64) and Access 2013. On Win7 (x32) and Access 2010 the following error is displayed:
„Object doesn't support this property or method“
(Error Code 438)
After manual deinstallation of the mentioned updates the VBA-code executes as expected. ListBox seems to be unusable after one of the updates. All other workarounds trying to fill the ListBox cause the same error.
Fast Help is very appreciated.

Hi,
Would you please to tell us which KB caused this issue? As far as I know, after installing
MS14-082 (part of December 2014 Public Updates for Office) you might get the error run-time
error '438': Object doesn't support this property or method, when clicking on the enable content button.
If you have installed MS14-082, please try to install the hotfixs that released in the March 2015:

My laser jet 100 color MFP M175nw is not working after windows 8.1 upgrade,

my laser jet 100 color MFP M175nw is not working after windows 8.1 upgrade, driver on your website fails to setup at 83 % with an error message

Welcome to the HP Forums MillaMagia,
I see by your post that the USB isn't being recognized.
I can help you with this issue.
Are you using the same USB cable? (known good USB cable)
You want to use the normal USB slot 2.0 cable and not the latest USB 3.0.
USB 3.0 are supposed to be backwards compatible.
Try another USB port on the Laptop, some of the USB ports are more powered then others.
I have provided a document to see if the printer is partially recognized in the device manager, which is causing the printer not to be recognized again. (the uninstall from the CD should have removed the entry and the printer from the registry)
Leave the printer turned on and the USB cable connected directly to the computer and the printer's power cord directly into a wall outlet.
How do I get into Windows Device Manager?
Here is a document for Identifying problems in Windows Device Manager.
Check to see if there are any hardware driver conflicts, you might see a ! mark or a red x beside a device with a conflict or unknown device, look under universal serial bus controllers, look for USB printing support or mass storage device, delete the entry by right clicking and select uninstall, OK.
Let me know how it was listed. (screen shots welcome)
If this is a Laptop then check the power management settings.
Access the device manager. Windows 8-How do I access the Device Manager.
Select universal serial bus controllers from the list, for each USB root hub, right click and left click on properties, for power management remove the check mark for "Allow the computer to turn off this device to save power". It allows the computer to limit or turn off power for this device.
Disconnect the USB, run the full uninstall and reinstall the printer software again.
If you need further assistance, let me know.
Have a nice day!
Thank You.
