Laptop Compaq CQ58: LAN Ethernet does not work after the upgrade to windows 8.1

After the upgrade of Windows 8 to 8.1, my Ethernet LAN is no longer in effect. Wireless LAN connectivity is OK. I run the HP Support Assistant and downloaded the drivers for 8.1. Hovever, I don't see a listed 8.1 for the LAN Ethernet driver.

It seems that you encounter the same problem, I did when I ran the free preview of the W10. I had this error on the card reader.  I have no idea how to solve this problem.

Is there is no ethernet controller needing drivers in Device Manager, then it is probably the realtek lan adapter that has the number 12 of the code, or it is part of the motherboard that controls the ethernet adapter.

If you need Atheros bluetooth driver, then this is probably the one you need.

Unfortunately, I won't be able to help you with question 12 code or ethernet.

IMO, they are insoluble.

  • HP Probook 6465b: Broadcom 4313gn does not work after the upgrade to Windows 10

    My laptop is HP Probook 6465b (model 2012) it came with Win 7 Pro pre-installed.

    I upgraded Win 10 and after that a Wi - Fi connection does not work. Then I tried the new facility, but it's the same thing.  I have come back to Win 7, but I would like to upgrade Win 10 if I can get the WiFi adpter for work.  My laptop otherwise works fine and it is not that old so I am confused why this wi - fi adapter gives me grey hair.

    Here is what happened:

    Just after upgading wi - fi works very well until the first stop. After reboot, free WiFi does not work and there is no wi - fi adapter in Device Manager. However, it's there, but it is hidden.

    I tried freezing and relocation of the map and I downloaded the latest drivers from HP Support, but I can't get the adapter to work.

    To get the internet to work I plugged USB wi - fi adapter and suddenly the WiFi Broadcom card started working also. She even worked after unplugging the wi - fi USB adapter but after reboot internal wi - fi adapter was missing again well (hidden and does not), it is too compligated to do each time and she even does not work every time, just every now and then.

    Any suggestions?

  • Micro does not work after the upgrade to windows 8

    Hello

    Today I have upgraded to Windows 8 Pro and spoke with my friend while he was installing/downloading. My audio and microphone worked perfectly, but when Windows 8 was installed, I called him on the steam and Skype, and he couldn't hear me. My volume is also extremely low, and I hear a hum, like a working machine, all the time. I have a headset Steelseries Siberia V2, and I realized that it is a software problem (I tried to use my headset on different pc and it worked everywhere else, except for my office). The microphone is visible in 'Her' where it is simply called 'High Definition Audio'.
    I don't really know what to do and I searched on the web every day, but none of the solutions have worked so far.
    My PC is an Acer Predator G3620 i7

    (If you need additional information, just tell me)
    Most often when a device does not work, it is because the driver is damaged. Re-install a new copy should help

    If you're having audio problems with Windows 8 does not, I would recommend reinstalling the drivers from the swsetup folder. I've seen this work with some laptops, but your results may vary.

    1. go to your C:\ folder and search for "swsetup" and select this.

    2. once in this folder, find the folder "drivers" and select the "audio" folder

    3. once in the folder audio, we are looking for the file "setup.exe".

    4. select it and run it. Once completed, restart the computer.

    I have a HP Pavilion DV6XXX laptop computer series (MS Vista Home Premium has been loaded from the factory), recently updated with Windows 7 Home Premium.  It is then this problem began.

    Wherever I am, everything I do (typing, surfing, reading) my cursor made a break of about 3 seconds, 26-28 seconds.  This interruption is making me crazy!  Everything what I'm typing, the cursor becomes unavailable for 3 seconds.  Everything I typed is gone.
