Flexibility for Users

Not every user wants the same Wi-Fi standard. Some are fine with Wi-Fi 5, while others want Wi-Fi 6 or Wi-Fi 6E. By omitting built-in wireless, MSI lets you choose the exact adapter that fits your needs and budget.

Product Line Differentiation

Motherboard manufacturers often reserve built-in Wi-Fi for higher-tier or specially branded models. Within the broader B450 and B550 families, MSI and other brands offer “AC” or “AX” variants that include wireless connectivity at a higher price point.

How to Confirm Whether Your Motherboard Has Wi-Fi

If you already own a B450 Tomahawk Max or you are looking at a used board, you can verify its wireless capabilities in a few simple ways.

Step 1: Check the Rear I/O Panel

Look at the back of the motherboard where the ports are located. A motherboard with built-in Wi-Fi typically has two gold-plated antenna connectors (SMA ports). The B450 Tomahawk Max does not have these connectors.

Step 2: Review the Official Product Page

Visit the manufacturer’s website and look up the exact model name. The specifications page will list “Wi-Fi” or “Wireless LAN” under networking if the feature is included. For the B450 Tomahawk Max, you will only see the Realtek Gigabit LAN controller listed.

Step 3: Check Device Manager in Windows

1. Right-click the Start button and select Device Manager.
2. Expand the Network adapters category.
3. Look for an adapter with “Wireless,” “Wi-Fi,” or “802.11” in its name.
4. If you only see a Realtek PCIe GbE Family Controller or similar Ethernet adapter, your system does not have active Wi-Fi hardware.

Step 4: Inspect the Box and Manual

If you still have the original packaging, check for included antennas or mentions of wireless connectivity. The B450 Tomahawk Max ships without antennas because it has no wireless module.
