    This might be possible on CloudReady but to help I'd need some more detail. Can you go through the process on CloudReady once more and take screen shots along the way of the cmds and any output they create?

    So when booted to the usb, I can't turn on WiFi, it turns off by itself. I press ctrl + alt + F2 to get to terminal. Then I login as chronos and I tried first to follow these steps: https://neverware.zendesk.com/hc/en-us/community/posts/360020839593 

    But there's no /firmware-6.bin on the latest cloudready, the path is sudo rm /lib/firmware/ath10k/QCA9377/hw1.0/board-2.bin or board.bin.

    Then I tried to do the WiFi settings I do in Linux cp /sys/firmware/efi/efivars/nvram-* /lib/firmware/brcm/brcmfmac43340-sdio.txt

    But there's no nvram folder in /efivars.

    So the last thing I tried was following this: https://neverware.zendesk.com/hc/en-us/community/posts/115000946148-HowTo-get-Broadcom-802-11abgn-Wireless-SDIO-Adapter-to-work 

    So I just: cp * /lib/firmware/brcm

    and then: sudo rmmod brcmfmac
    sudo modprobe brcmfmac

    But still no success, WiFi is not working.

    It might be the case that CloudReady can't find/access the nvram firmware file you're looking for. If that's the case, you can liveboot another Linux distro that can see it, like Ubuntu, and copy that firmware file to a separate external storage device (like a normal USB device or an SD card).

    You can then use that file, from the same external storage, instead of grabbing it from the nvram path, on CloudReady following otherwise the same steps as you were originally trying to follow (mostly as you do in Linux).

    I did disable verity and then rebooted. But now I realized that maybe I have to install cloudready to the hard drive so that those settings remain?

    I grabbed the brcm firmware from Linux and I put it inside /lib/firmware/brcm folder in cloudready USB. Should I put it somewhere else maybe? Or if I install cloudready, then load the firmware from a USB like you said, where should I copy the firmware to?

    Thanks for helping!

    I believe you'll need to
    1) reimage your usb
    2) install to internal disk
    3) make your changes
    4) re-make the changes after each update

    Note that I still can't guarantee that the wireless will work in the end, so if the risk of installing CloudReady to your internal drives and then later having its WiFi still not work, you may want to halt here.

    Wow! Finally, I got it to work!

    I reimaged my USB and installed cloudready to my internal disk. Afterwards, I disabled verity and rebooted. But still, I couldn't get the WiFi to work! I saw that the drivers I need already existed in the /lib/firmware/brcm/ path, but I couldn't find the nvram path, so something was missing there.

    So I followed this guide for debian linux on the T100HA: https://wiki.debian.org/InstallingDebianOn/Asus/T100HA 

    and it says: mount -t efivarfs efivarfs /sys/firmware/efi/efivars

    So I mounted those paths and Voila! I could find the nvram path. So I just did what I used to do in Linux: 

    cp /sys/firmware/efi/efivars/nvram-* /lib/firmware/brcm/brcmfmac43340-sdio.txt
    modprobe -r brcmfmac
    modprobe brcmfmac

    and WiFi now works and I can use the laptop.

    Only problems now is: 

    1. Brightness: I can't adjust it and I don't know how to fix that, if I can change display drivers somehow.

    2. Audio: not working! Same here with missing drivers I think.

    3. Mouse: two fingers scrolling. I had that problem in some linux distros to, it was only in Fedora I got that to work

    4. Sleep: I don't think my laptop really sleeps, but it never worked in Linux too so.

    Otherwise I really like this! More fast and stable than linux.

    @Isaac:  "Voila! I could find the nvram path."

    Which command I need to find nvram path?

    Thanks

    Lucio Carlo to find the nvram path, you need to: mount -t efivarfs efivarfs /sys/firmware/efi/efivars
    After that, you can find nvram path at: /sys/firmware/efi/efivars/

    I sold my laptop for almost a year ago, but that was how I solved the WiFi-problem.

    @Isaac Eventually, I used this command: cp brcmfmac43430-sdio.txt /lib/firmware/brcm/

    Wifi it's ok now.

    Thanks

    Hello!
    Regarding broadcom Wi-Fi adapters, I have got my hands on a Dell Inspiron 15R N5010, which ships with a D1501 PCIe Wi-Fi module that uses the BCM4313 chip. CR is reporting it as 5GHz compatible in the chrome://system page, though it is not. Here is a link explaining the 5G support dilemma.

    https://www.dell.com/community/Networking-Internet-Bluetooth/DW1501-does-not-see-5ghz-network/td-p/3522963/page/5

    I swapped that card with my Intel Centrino N-130 from my Samsung NC110 and it works fine on the Inspiron, but, on both machines, the DW1501 won't connect to secure (password protected) networks. It does not discover any. I tried Majaro Linux 19.02 and the card worked fine. I know the Inspiron is on your certified devices list, so I am not sure whether there was a recent regression with CR 80.3 and 81.1. Any help would be appreciated. I have already sent feedback from the device's feedback section.

    I'm no password sercuity except but are you sure that card supports the sercuity methods in which your network provides? That card looks old also

    As I said, no problems on Manjaro, or even Windows 7. There's an issue with CR.

    Eray,

     

    Exactly what type of wifi network are you having issues with?

    Hi, Forrest Smith!

    With this adapter, CR won't discover, nor connect to WPA-2-secured networks. Only w<connects to ones with no password set. It also thinks the adapter supports 5GHz, but it doesn't.

    Umm... from my search it does supports 5GHZ Band and with Wireless "N" so yes it supports it but to my search most didn't get the speed they were hoping for though

    Joe There has been wrong advertising about 5GHz support. Please, check the pinned link. And the max speed is 72 Mbps.

    OK, so plz confirm if all the below is correct, Eray Rafet

    PROBLEM: BCM4313 wifi will not connect to WPA-2 password protected networks. This wifi chip has the same issue in both v80 and v81 CloudReady. It also behaves the same way whether inserted into a Dell N5010 or a Samsung NC110.

    All sound correct?

     

    If so, here are some additional questions:

    • How many different WPA-2 networks have you tried connecting to? 
    • What types/how many non-password-protected networks have you confirmed working?
    • Have you tried connecting to a smartphone hotspot with password protection?
    • Have you tried disabling password protection on your home router to confirm that CloudReady can then connect?
    • When you mention "It also thinks the adapter supports 5GHz, but it doesn't " do you mean that the device picks up 5GHz-only networks but can't connect? or something else?

    Hi!
    1. Around 5. First of all, they don't even get recognized.
    2. Only one.
    3. Tried, still no luck.
    4. Yes, also wasn't picked up.
    5. Yes, no luck there too.
    6. The chrome://system page shows the adapter as 5G capable, but it really doesn't on a hardware level. The pinned link explains that whole wrong advertising debacle. Maybe there's some connection?

    I hope things are clear now.
    PSA: I don't have that Wi-Fi card anymore.
