Windows 8.1 update disabled all networking

After a very long install time (about 2 hours, actually – surprisingly for the “new” Microsoft way) my Acer TravelMate notebook has been “successfully” upgraded (without any error messages) from Windows 8 to the recent 8.1 version (the update being available for free – that’s very good!)

Logging in to my user account for the first time (requiring more minutes while the computer was still “configuring a few things” – a few?! oh well…) I was shot in the head: no network connection was available anymore. Neither wired (Broadcom NetXtreme Gigabit Ethernet) nor wireless (Intel® Centrino®) connections were available anymore.

Device Manager was showing the two network adapters with warnings related to error “Code 12”, indicating that the devices “cannot find enough free resources” to be able to run. (Their drivers were reported as available, loaded, and up-to-date.)

After some Web searching, I found out nearly nothing, as most similar issues were for previous operating systems. However, there was one recent discussion which saved me: the provided solution was to disable the card reader device.

As soon as I did that (selecting Disable from the context menu of O2Micro item listed in Device Manager under PCMCIA adapters group), both network adapters started to work well! (And I can – at least temporarily – re-enable the card reader after the network starts, if I really need to use it.)

    A great thank you from the Netherlands. You solved my problem with windows 8.1 and the network drivers. It looked like I could use my laptop only with windows 7, had to buy more software ( part from this 8.1 I already bought) or a new laptop. Acer told there where no more updates available. Who needs them!

    Hi (excuse my English translator),
    It is a year and a half I had this problem.
    Indeed on my Acer Travelmate 7730G (17 “), which I use as desktop computer, I had been in Windows 8 Pro.
    I tried them all, all, to start the driver ETHERNET (BROADCOM NETLINK) and Intel wifi but nothing, nothing! I was promptly forced to return to the pro version 8.
    I had resigned myself! The Pc had passed through the hands of my friends technical profession!
    Nothing!
    The sentence: Your Acer can not be upgraded to Windows 8.1 PRO!
    Well yesterday looking in his spare time (not entirely resigned …) on the web I came across a few on your line! I followed what you wrote …. e..TUTTO SOLVED after a year and a half I have my PC with WINDOWS 8.1 PRO!
    I’m happy!!!!
    THANK YOU
    Oh please! If by pro windows 8.1 to windows next 10 I will have problems … you wait !!!🙂
