Driver Ethernet and network controller missing after the Installation of 7 costs Windown


I have Sony Vaio VPCEG25EN E series laptop with Win 7 64 bit pre installed.

I had installed Win 8 intended to test and when it is again installed win 7, I'm missing my network and Ethernet controller drivers. I don't see any network except for Bluetooth network card adapters.

Tried to install the drivers from the SONY site but in error.

Apart from these 2 drivers

PCI device
Simple PCI controller communications

SM Bus controller

are also missing.

Please let me know the solution how to install the drivers and where to look for it.

IMP Note: if I install the trial win 8 again, I'll have all my drivers after installation, but during the installation of Win 7, they disappear.


What error do you get when you try to install the drivers of sony?  Windows generic drivers should work...  In Device Manager, do you have a selected and right click 'check for changes on the hardware?

  • NB510-109 - driver missing for Ethernet and network controller

    Hi again

    I replaced the HARD drive on my NB510-109 and installed W7 32-bit teacher. Windows unfortunately has no Driver for my network controller and Ethernet. The seller of Ethernet is 1969 (Atheros), but the driver I found does not work.

    The seller of network controller is 10EC (Realtek or Acer) but I can't find a driver.

    Is there a link where I can load the original driver CD/DVD?

    PS: I could not save the original data of my old HDD for HARD drive has not finished.

    Are you looking for driver LAN or WLan driver?
    I m asking because the network controller could mean the WLan or LAn card.

    However, the laptop supports the Atheros LAN card and you must install the Atheros LAN driver.
    The WLan card is made but Realtek. Its 802.11bgn RTL8188CE card Wlan.

    On the page of the Toshiba UE driver you can find two drivers Atheros LAN to Win 7 32 bit:

    I recommend you to check them both.

    Realtek WLan driver can be downloaded from Toshiba WLan Portal:

    I bought a win8 system. I tried to install the Canon MP160 driver on the system.

    Now I have problems with the installation of MP Navigator to scan.

    Hi Pavan,

    Thank you for the information.

    You can uninstall the drivers from Device Manager and try to install the latest versions to check the issue.

    If the problem persists, try to install the software of the browser in compatibility mode and see if that fixes the problem.

    You can also get in touch with the Canon Support for assistance on their products and compatibility.

    It will be useful.

  • Joined to a domain and an administrator remote after the installation of SP1, updated to 10 settings (clean install) then

    Wipe the hard disk, reformatted and did a clean install of OS7 home (fossoyées pro hoping group domain policies and etc. would not be a problem).  But they are still there. Reinstalled again.  I can't remove the files manually, give me permission. Loading guard who looks like a fake update file, but I can't delete that either.  I'm at my wits end.  I also have a problem with one of my Outlook email accounts, displaying a string of what looks like a key under my user name.  I have dealt with this for 2 months.  had my machine to two different local mechanics and nothing.  Even exchanged the motherboard and the drive.  How's it relate?  I do not even use the same key.  The only way he could do it is through my network connection. (Disabled Wifi too).

    I read something on the Panther Trojan and I do not have a file of Panther on my machine (which again, I can't delete).  I didn't even think that HOME version had this kind of remote administration and yet it moves it. Its load of 32-bit strange file and run it on a 64 bit system.  I don't know what to do from here.  I can't get a version of Windows installed which does not suck up all my processing power and crazy amounts of data transfer.  I pulled out an old HP Pav and am now loading XP on it.  At least I will be able to view and edit files it contains.  I don't think safe, even check my email on this machine. (I use my ipad for that).

    Here are the results of the queries from the command line, screenshots and event log shears.   Since I was the last reinstall at about 21:00 there are 294 Logon and created special logons.  Not to mention that I had an another windows machine and one android corrupt their hooking up to my Dungeon phone.  The worst is a 10 years ' worth of my design files holding external drive.  Sighhhhhhh...

    IM so sick of looking at this.  Im going to bed and hopefully not dreaming about it.  If someone can tell me how to stop this happening, I would SO appreciate it.  Support for Windows is a joke.

    I have run 3 different programs of Virus Scan on it, reformat the drive twice (wiped to zero once), and used three different install media (three different versions of Windows. 0 s 7 home, pro and pro OS7 OS10 (7 pro is what I was running when this began).)  Again, it is after that I paid two services of different repair to diagnose, pull the wireless network card, replace the motherboard and replace the disk.  After that I freaked out on them they began to throw the installation discs and Home keys. lol seriously, I might as well throw my money down a hole. (the key I've finally pulled the machine isn't that I've never owned?) I guess that's why I'm trying so hard to get pure installed, I already so much money in it.  I should probably just give up and load Linux.

    If I ever get my hands on this bloody trusted installer it is a dead man. Thanks in advance!

  • Network stops working after the installation of the VMware Tools on linux comments


    I m facing problem after that, sometimes, sometimes not after a comment tools and vmware linux installation.

    If the installation of vmware Linux tools everything seems to work perfectly. No errors, nothing.

    The last thing to do after that tools installed will run successfully is to run the following commands (produced by the message from the installation program tools)

    /etc/init.d/network stop

    rmmod pcnet32

    rmmod vmxnet

    modprobe vmxnet

    /etc/init.d/network start

    This works fine as well, but after the next reboot the network stops working sometimes.

    The linux guest runs under VMware Server 2 using tools VMwareTools - 2.0.0 - 122956.i386

    The strange thing is that this happens all the time when install linux clients and tools.

    Guest operating system is RHEL40U5

    Any help how to avoid this is much appreciate.

    Better with respect to Agent.

    Why not add the commands above to the file etc/rc.d/rc.local. It will take a cae of the rest every time that you restart your virtual machine. I hope this helps...

  • Problem: My computer hangs and does not restart after the installation of MS Update KB2479628.

    Tuesday February 11 I turned my hp Compaq nx7300 off I saw that she was installing updates I thought that nothing of what I had set to automatic updates. On Wedndesday that I have tried to re - turn on my laptop it installed updates. I got a black screen with white writing. The laptop then ran restoration of boot, but he was not able to repair itself and turns off. I tried to turn it back on a few times that I was in total disbelief that a MS Update would do this to my computer, it still does not.

    I tried to start the computer in safe mode, but it does not work.

    I tried to do a system restore but evertime I tried it there was an error, I tried all eight restore points but all back "an unspecified error occurred during system 0x800700b7 restore.

    "In restoration of start I clicked on ' view diagnostic and repair details" it said all tests have been performed with success, but at the bottom it says ' root cause found - boot critical file D:\Windows\system32\ntkrnlpa.exe is corrupt.

    I had to reinstall windows 7 pro three times so far and have now developed to the point that it is KB2479628 update of MS that is causing the problem. I the have not installed this time and have had updates to the manual

    What can I do about this problem, I spent at least 20 hours on this problem now, and looking for the many other forum of people seem to have similar problems. I'm worried that KB2479628 will settle by accident when I want to install some other updates?

    My computer laptop originally had Vista Business top but has been upgraded to Windows 7 32 bit, clean install, I use Microsoft Security Essentials, I've never had installed norton or macafee.

    Thank you very much for all your time and your help is greatly appreciated, I'm sure I'll be at the time when SP1 is available.

    Until then your your :-)
