So try broadcom-wl-dkms

Try this. Append the following kernel parameter:

appuals.com/ How to Partition and Configure Drives for Linux UEFI Boot By Kevin Arrows

I cribbed the gdisk stuff in the above log from this. It works. Run gdisk /dev/sda from a root prompt. Running wipefs -a /dev/sda is a good way to eliminate any signatures from the drive, but once again this will render everything you currently have on it inaccessible.

wiki.archlinux.org/ GRUB - UEFI systems

I used this as a guide. It worked. First, install the packages grub and efibootmgr: GRUB is the bootloader while efibootmgr is used by the GRUB installation script to write boot entries to NVRAM. Then follow the below steps to install GRUB: Mount the EFI system partition and in the remainder of this section, substitute esp with its mount point. Choose a bootloader identifier, here named GRUB. A directory of that name will be created in esp/EFI/ to store the EFI binary and this is the name that will appear in the UEFI boot menu to identify the GRUB boot entry. Execute the following command to install the GRUB EFI application grubx64.efi to esp/EFI/GRUB/ and install its modules to /boot/grub/x86_64-efi/.

        grub-install --target=x86_64-efi --efi-directory=esp --bootloader-id=GRUB

After the above install completed the main GRUB directory is located at /boot/grub/. Note that grub-install also tries to create an entry in the firmware boot manager, named GRUB in the above example. Remember to Generate the main configuration file after finalizing the configuration. Remember that /boot/grub/grub.cfg has to be re-generated after any change to /etc/default/grub or files in /etc/grub.d/. The default file path is /boot/grub/grub.cfg, not /boot/grub/i386-pc/grub.cfg. If you are trying to run grub-mkconfig in a chroot or systemd-nspawn container, you might notice that it does not work, complaining that grub-probe cannot get the "canonical path of /dev/sdaX". In this case, try using arch-chroot as described in the BBS post. If you are installing GRUB in chroot environment using LVM and the grub-mkconfig hangs indefinitely, see #Device /dev/xxx not initialized in udev database even after waiting 10000000 microseconds. Use the grub-mkconfig tool to generate /boot/grub/grub.cfg: grub-mkconfig -o /boot/grub/grub.cfg

wiki.archlinux.org Network configuration/Wireless

The main article on network configuration is Network configuration Configuring wireless is a two-part process; the first part is to identify and ensure the correct driver for your wireless device is installed (they are available on the installation media, but often have to be installed explicitly), and to configure the interface. The second is choosing a method of managing wireless connections. This article covers both parts, and provides additional links to wireless management tools.

wireless.wiki.kernel.org About iw

iw is a new nl80211 based CLI configuration utility for wireless devices. It supports all new drivers that have been added to the kernel recently. The old tool iwconfig, which uses Wireless Extensions interface, is deprecated and it's strongly recommended to switch to iw and nl80211. Like the rest of the Linux kernel, iw is still under development. Features are added 'as we go'. The only documentation for iw is this page and output from 'iw help'. Please help expand this page.

w1.fi/ Linux WPA/WPA2/IEEE 802.1X Supplicant

wpa_supplicant is a WPA Supplicant for Linux, BSD, Mac OS X, and Windows with support for WPA and WPA2 (IEEE 802.11i / RSN). It is suitable for both desktop/laptop computers and embedded systems. Supplicant is the IEEE 802.1X/WPA component that is used in the client stations. It implements key negotiation with a WPA Authenticator and it controls the roaming and IEEE 802.11 authentication/association of the wlan driver. wpa_supplicant is designed to be a "daemon" program that runs in the background and acts as the backend component controlling the wireless connection. wpa_supplicant supports separate frontend programs and a text-based frontend (wpa_cli) and a GUI (wpa_gui) are included with wpa_supplicant.
