    Windows 10 21H1 and WiFi Adapter


    Among my various computers, I have an ASUS X205TA which is a 32-bit tablet. I have been installing the latest 21H1 version on my computers and the tablet is the last however, when attempting to install 21H1, before the actual installation begins, I get an error message stating that Windows 10 is not compatible with the Broadcom 802.11agbn wireless SDIO adapter and the installation of 21H1 will go no further. The tablet was originally running Windows 8.1 but I converted to Windows 10 with no problems.

    I tried disabling the adapter first but that resulted in the same message. Does anyone have an idea how I can bypass the adapter and get 21H1 installed? I have not tried uninstalling the adapter via Device Manager. Searching the web for an updated 32-bit driver yields very little. My current driver is version 5.93.102.19 dated 2017; there is also a Microsoft driver that is dated 2015. Any ideas? Any driver available dated later than 2017?

    Hi, whilst you might be able to force the installation of 21H1 using
    How to Disable Safeguard Holds for Feature Updates on Windows 10
    (not sure if that overcomes what you're seeing)
    - and you can manually apply the upgrade using an appropriate iso or the enablement package as appropriate

    you will be left with either non-functional Wifi or a struggle to find a way to get it to work- which may or may not be possible.

    That you have upgraded to Win 10 with a device presumably never designed to run it does not guarantee that you can continue to upgrade successfully.

    Don't know what build you're running, but upgrading from 1903 to 20H2 on this, which I did recently, then to 21H1, was a functional downgrade, plus gave me 4 issues I had to resolve (not driver-related).

    Why not simply stay on a build that works? There are easy ways to do that.

    dalchina, you're right in saying why not stay on the build that works; I am currently running 20H2 on the tablet. Personally, I like to keep my computers running on the latest version but I'll probably have to leave the tablet on 20H2 due to the WiFi. But it's just curious why 21H1 does not like the WiFi adapter. I've read about others upgrading and they find out after the upgrade that a component won't work, not before it actually starts. Normally, with components that are built to work on 8.1, I can usually find a fix or driver version that will work on Windows 10 and, there are a number of drivers that I found for the adapter that are specifically for Windows 10. Presumably, Microsoft have taken a different view of that adapter or 21H1 has been changed in some way.

    In any case, thanks for your message and I'll probably do as you suggest.

    Can you disable the WiFi adapter in Bios? If you can then the update will not even see it.

    There was a similar thread recently
    Cannot connect to wifi after upgrade to Windows 10 - TenForums
    so perhaps there is some useful guidance in it for your situation.

    Perhaps there is an online article describing how to remove, or even replace, the WiFi adapter for your brand-model.

    Best of luck,

    Denis, I haven't thought about the bios and whether I can disable the WiFi so I will try that and I may look for a replacement chip.
    Thanks for your suggestions.

    I once considered that for my own tablet's useless 802.11n card but could not find any servicing info on the maker's site [I think they are not made with replacing parts in mind] or their user forums and could not find any online articles claiming to have been able to do it.

    So if you do figure out how to do it I'd be interested in your experiences. Even though it's a different brand-model, your insights might be very useful.

    Best of luck,

    I'm confused.

    You say that your current driver is 5.93.102.19, and it's from 2017. ASUS EeeBook X205TA - Support lists 5.93.103.20 as from late 2015, and for Win10 X32.

    I haven't had a problem with any Win10 driver failing with a later Win10 release. I'm not running the X86 (32 bit) version on nay device, though.

    bobkn, believe me I'm confused as well. I listed my current driver as 2017 because that is the date displayed in Device manager. I saw ASUS driver yesterday on their support site and, because the numbering of the driver is higher than my current driver, I downloaded and installed it with no problems on 20H2. The fact that it is dated as 2015 made me scratch my head. Could it be that the numbering system for drivers is a bit screwy? It wouldn't be the first time that I saw a later driver version with an apparently lower version number but it is unusual.

    All, although I haven't made progress, I have found out that the Broadcom WiFi adapter is soldered onto the motherboard so I can't remove it. I thought about prying it off but I would probably damage something else. I also read about the "Disable safeguards for Feature Updates" that Microsoft recently introduced, and it seemed like that would solve my problem however, after setting the registry to disable safeguards and trying the feature update again, it did the same thing - it will not let me install 21H1.
    While it's interesting trying all these possible fixes, they still do not fix the problem so, I think I'm stuck with 20H2 until that version is no longer supported. Quick question to all - if it were you in my place, would you try removing the adapter from the motherboard either by prying it off or other means, would you do it and how? Keep in mind that this is a computer I don't use very much so, if there's a chance of success, I might attempt it.
    Thank you all who have contributed so far.

    Keep running with the build that works. Bear in mind that 'not supported' or 'end of service life' doesn't mean that it will suddenly stop working- you'll just not receive any more routine updates.

    With such a device, simply stay with what works.

    Upgrading to 21H1 gains you nothing functionally.
