Modprobe knows which drivers rtl8723de depends on and should therefore be able to add everything that rtl8723de depends on along with rtl8723de. On a side note: for the final step you might be able to get away with just writing: sudo modprobe -r rtl8723de MOK.der $(modinfo -n rtl8723de)įinally, add the rtl8723de drivers to the kernel in this order sudo modprobe -r rtlwifi Sudo /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256. sudo /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256. So use the keys you generated earlier to sign your drivers. Your drivers are available for adding to your kernel, but you need to sign them first before adding them because you have secure boot enabled.

You will need to install the drivers for you wifi. Assuming that worked, then you'll want to test that your MOK was successfully enrolled. You should have been prompted by your BIOS for the password. Your BIOS should prompt you for the password after the reboot. You'll be prompted for a password here, which you'll need to remember. If the bcmwl-kernel-source solution did not work for you and you want to keep secure boot enabled, then try the following:Ĭreate a set of keys for signing: openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=Descriptive common name/" Hard blocked: no Settings > Wifi > move to On > select your Wiki connection to enter credentials Running below command in Terminal, you can see the issue: But I mistakenly pressedįn + F12 which was Wifi button with 'Radio' symbol on it, which disabled my wifi connection. I tried to increase volume with:įn + F10 key combination.

With a bit of luck, installing this firmware package and rebooting might be enough to get your Wi-Fi functional if the necessary driver is already in kernel. If Ubuntu uses the same naming scheme as Debian, the firmware package name should be firmware-brcm80211. Note that the supported Broadcom chips will need firmware: it is probably available pre-packaged in Ubuntu. You can check here for the Linux support status of various Broadcom chip models: The lsusb listing is a bit different, but the Device ID number is similar: 4 hexadecimal digits for the vendor id, a colon, and then 4 hexadecimal digits for the product ID.
The first part specifies the vendor (Broadcom = 14e4) and the second part identifies the device model.
The lspci -nn listing line might look something like this: 12:00.0 Network controller : Broadcom Limited BCM43228 802.11a/b/g/n Lspci -nn would be a good command to list all PCI(e) devices on your laptop and their PCI ID numbers: those numbers would allow a more accurate identification. "802.11n" is just the name of the Wi-Fi standard it supports: Broadcom has several wireless chips supporting that standard. First, you'll need to find the exact model of the Broadcom network adapter chip your notebook has.
