524WiFi recently announced the compatibility of Dream m.2 module DR9074-TRIBAND with ATH11K on Linux, expanding its support beyond Qualcomm platforms to various Linux embedded systems, including Ubuntu. In this guide, we’ll walk you through the process of loading the driver for DR9074-Triband on Linux 5.17.0, demonstrating its seamless integration with ath11k. The module is showcased to function effectively in both AP (Access Point) and STA (Station) modes across the 2.4GHz, 5GHz, and 6GHz bands.

Introduction to DR9074 (QCN9024):

DR9074-Triband, equipped with the Qualcomm Atheros QCN9024 chipset, is an advanced enterprise wireless module. It incorporates a 4×4 MU-MIMO Dual Band Wireless Module, tailored for mobile access in high-bandwidth applications such as video streaming, voice communication, and data transmission. Key features include a maximum power of 23 dBm per chain, supporting data rates up to 4949Mbps. Operating in Tri-Band (2.4GHz, 5GHz, and 6GHz) with 4×4 WiFi 6E (802.11ax) and 4 spatial streams, it features an M.2 E Key Interface and PCI Express 3.0 Interface.

1.Downloading the Ubuntu 22.04 version.

2.Compiling kernel version 5.17.0 to include support for ATH11K 9074

Driver Loading Steps:

Compile the driver.

Navigate to the firmware folder and copy the card firmware.

Copy the compiled driver to the designated path.

Compile hostapd.

Configure hostapd compile option

Complete configuration, commence making, and install.

Verify the successful installation of the current version, then run hosta

d.

Confirm the presence of the DR9074 card.

Validate the functionality of 2.4G/5G/6G under AP mode.

Compile the tool for STA mode and configure compile options.

Finish compilation, check the version (returns as 2.10 for successful compilation), then run.

Confirm the functionality of 2.4G/5G/6G under STA mode
