Hey there! Sorry to hear you're hitting WiFi and Bluetooth snags with your new ASUS Vivobook 17 on Ubuntu—let's work through this step by step. First off, huge props for helping friends set up Ubuntu over the years, and welcome back to Linux after your Mac stint! 🚀

Let's start with the basics to pinpoint exactly what's going on:

Step 1: Grab Key Hardware Details #

First, we need to know exactly what WiFi/Bluetooth chip your laptop uses. Open a terminal and run these commands, then share the full output:

• lspci -nn | grep -E "(Network|Bluetooth)" (shows PCI-connected wireless/bluetooth adapters)
• lsusb (covers USB-based adapters—some newer laptops use these)
• dmesg | grep -i firmware (checks for firmware loading errors, which are super common with new hardware)

Step 2: Install Missing Firmware #

New ASUS laptops often use Realtek or Intel chips that require proprietary firmware Ubuntu doesn't always include by default, even after full system updates. Here's how to fix that:

• First, make sure the restricted/universe repos are enabled (they have the firmware packages):

  sudo add-apt-repository universe restricted
  sudo apt update && sudo apt upgrade
  

• If your chip is Realtek (super common in ASUS machines):

  sudo apt install firmware-realtek
  

• If it's an Intel chip:

  sudo apt install firmware-intel-sound intel-microcode
  

Reboot your laptop after installing these, then check if WiFi/Bluetooth appear.

Step 3: Check Kernel Compatibility #

Newer hardware often needs a newer kernel to work properly. Let's confirm your current kernel version:

uname -r

If you're on an LTS release (like 22.04), you can enable the Hardware Enablement (HWE) stack to get a newer kernel and drivers:

sudo apt install --install-recommends linux-generic-hwe-22.04

Reboot after this—HWE kernels are officially supported and often fix compatibility with new laptops.

Step 4: Double-Check Hardware/BIOS Settings #

Don't overlook the simple stuff!

• Make sure there's no physical WiFi/Bluetooth toggle on your laptop (some have a keyboard shortcut like Fn+F2 or a physical switch) that's turned off.
• Boot into your BIOS/UEFI and confirm WiFi and Bluetooth are enabled, and that Secure Boot is disabled (Secure Boot can block proprietary firmware from loading).

Step 5: Look for Model-Specific Fixes #

Since this is a new Vivobook model, other users might have already solved this exact issue. Search for your full model number (like Vivobook 17 X712EA) in Ubuntu's bug tracker or community forums—you might find a pre-built DKMS module or a specific workaround for your chip.

Once you share the output from Step 1, we can zero in on a precise fix. For example, some newer Realtek chips (like RTL8852BE) need a custom DKMS module installed manually because the default firmware isn't enough yet.
