Sleekbook 15 (D8X43U): Pavilion Sleekbook 15 WiFi unrecognized after opening case

I recently had to open the case and make a few disassembly to upgrade my memory. After reassembling the computer, my WiFi card is no longer recognized. When I go to Device Manager - network adapters I even see the device in the list. I wonder if I missed something on reassembly? Everything else seems to work fine (except the memory upgrade did not, see this discussion).

Can anyone suggest troubleshooting steps or specific items to check when I opened the computer?

Thank you

Hey @matkramer,

Welcome to the Forums of HP Support!

Please try the Troubleshooting tool from your wireless network and Internet connection. It took will walk you step by step through the process.

I did some research and found a great document for you called troubleshooting wireless network and Internet. This document will help you to solve the problem of Wi - Fi also.

Have you tried to restore the BIOS?

Do you get any error messages?

Says he in for network adapters Device Manager?

You have uninstalled the network card drivers in Device Manager?

Please, try the following:

  • Go to your Start menu/screen and type Device Manager.
  • Expand network adapters.
  • Right click on the wireless adapter and choose uninstall.
  • Restart your laptop twice.

If you receive one of these errors:

  • Internet Explorer cannot display the Web page.
  • Working offline: no connection to the Internet is currently available.
  • Not connected: you are not currently connected to any network.

Here is another document titled broadband to solve Internet connection problems.

Here is a link to the HP Support Assistant, if you need it. Simply download and run the application and it will help with the software and drivers on your system that need updated.

If you have tried the actions in the documents provided above and can not establish a connection or wireless continues to run poorly, your wireless adapter card may need to be reinstalled. This could be possible as you were simply by changing the internal parts.

The problem you are having with your wireless connection can be a problem other customers are wondering also on; Please click the accept as a Solution, if you feel helps you to this post, or could help others. You can say thank you easily by clicking on the Thumbs Up below!

If you need advice on where the internal network adapter is, I can do my best to find a document for you, but I would need your model number (How can I find my model number or product number?) to find the appropriate documentation if available.

Please let me know! I don't mind help!

Have a wonderful day!

  • WiFi lost after winning 10 improvement on Satellite P745-S4217

    Help! WiFi lost after upgrading to windows on my SATELLITE of P745-S4217 10

    Drivers have installed successfully but when I troubleshoot, windows tells me wireless capability is turned off

    I search on the net, but still no solution to my wireless connection interruption

    Any help will be appreciated thanks

    Hello

    In the past, you need to turn on the WiFi using the FN keys, but I think that this should not be necessary to help to win 10.

    In any case, I think that you must connect to the laptop to the internet using LAN cable.
    Then, you must uninstall the WLan Device Manager driver.
    After that, restart the laptop in order to win 10 to select the Wlan driver automatically.

    As far as I know that Win 10 must check for new drivers available WLan and in the best of cases after the update, the WiFi connection should work again.

  • Why can't connect using Apple Airport WIFI of my remote security cameras but can connect using the Xfinity WIFI Modem/Router open?

    Why can't connect using Apple Airport WIFI of my remote security cameras but can connect using the Xfinity WIFI Modem/Router open?

    Two possibilities:

    (1) your airport WiFi might have a network name that is not in line with best practices, wireless

    A good wireless network name is...

    ... In short no more than 20 characters

    Simple... no special characters like an apostrophe, dollar sign, asterisk, etc.

    Compact, without spaces in the name

    For example, a wireless network network name as... red .dfedoryk Apple wireless network... .is not what you want. Something like... .dfedorykwireless. .. masse are much more likely to connect to non-Apple devices.

    Same guidelines your password

    (2) Apple gives the same name to network 2.4 GHz and 5 GHz network that produces double router band.  Some non-Apple devices are confused by the present, you may need to use the option to assign a different name for the network of 5 GHz on the router from Apple. Then, 'point' your device to the network name specific to which you want to connect.

  • WiFi problem after upgrade to Windows 10

    Greetings!

    I read a few posts on WiFi problems after the (improper) upgrade of Windows 10. I have a ThnkPad T530 which I've upgraded to Windows 10 Windows 7 in September (too late to roll back). Here's my question:

    I have three computers on my desk. This standard T530 running Windows 10, a ThnkPad E555 running Windows 7 and a Dell running Windows 8. I used all three last Friday. I installed Norton on all three Friday and everything went without a hitch. When I first started their return to the top of this morning, the two others came online as usual. The ThinkPad T530 connected by a router in the company, but has no access to the internet. I can connect to the hotspot on my phone and it connects fine. I tried to turn the WiFi connection and then turn it on again, restart, by killing and restarting the business connection, etc. Nothing changes.

    Help, please

    Ben

    Try the following:

    Open administrator command prompt:

  • Recovery WIFI connection after sleep mode activation takes much too long

    This question of provenance in this thread: http://answers.microsoft.com/thread/b7916ba7-3e34-4ee2-a6e7-bba2fa65508b (title: "HELP!") Driver issue Microsoft Virtual Wifi Miniport Adapter (error code 31)").

    Basically, the presented solution it works for me too. However, the command "netsh wlan set hostednetwork mode = ban" does not get persistent, thereby affecting

    "stop wlan netsh hostednetwork" gets persisted, however.

    'do not command netsh wlan set hostednetwork mode = allow' does not get persistent...

    In other words, current enforcement in exactly ONE time orders-Admin-helps prompt - as soon as I wake my machine to sleep after running it, the WIFI connection gets restored quickly (less than 5 seconds); but when I check the status with "netsh wlan show hostednetwork", then the result is that the mode is set to "Authorized" again - and that means, the next time that I wake up the machine, it takes ages to new (~ 30-50 seconds) before connections WLAN gets implemented...

    Does anyone know how I can get the mode = do not allow to persist?

    Another fact interesting, that I found before I was running on the solution by using the NETSH commands:

    If I change the ' password on the reactivation of the "option of energy saving"require a password (recommended)"to"Don't require a password", it's okay, about the period of time it takes to establish the WIFI connection after wakeup (in other words, even without the NETSH commands described in this thread).

    So, from my point of view, it seems to be that something related to security (probably in association with this kind of things hosted network).

    The problem: disabling of "Protection of password on wakeup" is not a solution to everything, for me personally, as I am quite often on the road with my laptop, and I want to be sure that the data on my laptop is not accessible without unlocking the screen, in the case where the unit would get stolen or I loose it somehow... to protect all customer and other data sensitive data to this topic...

    Any professional entry of someone at Microsoft to finally have a solution for this would be greatly appreciated.

  • Pavilion Sleekbook 15: Wifi constantly out, computer freezing?

    I got about with my computer, honestly. Most recently, in the last month, my computer started putting my wifi in limited. For no reason. Yes, I tried all the fixes on the primary computer. Yes, I disabled disabling "allow" of it. It's just a waste.

    Not only it will go to limited, but it crashes completely hard from my computer (but sometimes only)

    I don't connect both until recently, because I always realized it is once the limited showed on my wifi.

    I don't know what is the cause. I made sure it's no virus, and I still have no idea. I really want to solve this problem.

    Thank you.

    Good news! I was able to fix! I looked towards the top as many bugs as I could and tried somehow several ads of things one of them worked. I don't remember exactly where I got these corrected since then, but one of them consisted of uncheck the "turn off this device to save power" on the usb root hubs.

    At the same time, I reset my router and re-turn off "disable this device to save power" when I put my wireless card driver. I don't know who it was... but my wifi did not come out for 15 hours. Hooray!

  • 15-b168ca Pavilion: Pavilion 15-b168ca sleekbook - no wifi driver detected

    Hello

    My wifi doesn't work.  At first, I could reset my computer and get it going again for a minute, but then it stopped working altogether.

    I 'reset' my computer to the point where my programs are lost but my records and documents are kept.  That did not work.

    A techie friend of mine had a quick glance and says that the wifi driver seems to be missing and plug in an ethernet cable and follow the necessary updates.  Cable ethernet worked, but the updates never came and my wifi still doesn't work.

    I thought that maybe if I install Windows 10, it could restore things for me, but that didn't work.

    I tried HP support auto troubleshooting for wireless network and internet (windows 10) but stuck to (5) under step 1 because where my HP Support Assistant should apparently give me a link to 'Check' HP network next to the 'connections', he said on the contrary "visit the Forums Support HP's.

    Troubleshooting Windows didn't help not my wifi because he just tells me to plug an ethernet cable.

    Also, I can't find the page, but the HP site did a search on my computer and he said he couldn't find it.  I can't give more details about this because I remember more where I found this link.

    Can someone please?

    Thanks in advance.

    Was not means that the wifi adapter no longer works as it should, in other words, it's a dead device.

    This is the reason why I asked you to run the diagnostic equipment.

    Test PC Hardware Diagnostic checks for the proper functioning of the devices installed in your laptop at the firmware level.

    Is your laptop still under warranty? A replacement wifi adapter are covered by the warranty?

    Check the status of your warranty here.

    If it is not in warranty, you will need to bear the cost of replacement of the module from your pocket.
