Vendor-agnostic guide to ALFA Network Wi-Fi adapters on Ubuntu and Kali Linux — identify your chipset with lsusb, then jump to the matching chipset-specific driver page.
Step-by-step Ubuntu setup for every ALFA Wi-Fi adapter — plug-and-play for in-kernel chipsets (MT7612U, MT7610U, MT7921AUN), DKMS installs for Realtek chipsets (RTL8812AU, RTL8811AU, RTL8832BU).
Every ALFA Linux driver guide in one place — MediaTek in-kernel chipsets (MT7612U, MT7610U, MT7921AUN) and Realtek out-of-tree DKMS chipsets (RTL8812AU, RTL8811AU, RTL8832BU, RTL8821CU), with links to each guide.
Which ALFA adapter works on which OS — Kali Linux, Ubuntu and NetHunter/Android — with driver, chipset and in-kernel status.
How firmware and drivers work across SDRLAB devices — RTL-SDR V4 drivers, TRX-duo SD images, H4M Mayhem firmware and Flipper Zero expansion firmware — with a decision tree.
MT7610U chipset deep-dive — the in-kernel mt76x0u driver used by the AWUS036ACHM, with monitor mode, verify steps and troubleshooting.
MT7612U chipset deep-dive — the in-kernel mt76x2u driver used by the AWUS036ACM, with monitor mode, verify steps and troubleshooting.
MT7921AUN chipset deep-dive — the in-kernel mt7921u driver behind the AWUS036AXM and AWUS036AXML (Wi-Fi 6E), including kernel requirements, monitor mode and Bluetooth.
RTL8811AU chipset deep-dive — the pocket-size AWUS036ACS, DKMS install of the rtl8811au driver, monitor mode and injection verification.
RTL8812AU chipset deep-dive — the classic high-power AWUS036ACH, DKMS install via aircrack-ng/rtl8812au, monitor mode and injection with airmon-ng.
RTL8821CU chipset deep-dive — the honest guide for the AWUS036EACS: why Linux support is unreliable, what the community driver offers, and when to pick a different adapter.
RTL8832BU chipset deep-dive — the Wi-Fi 6 RTL88x2BU driver behind the AWUS036AX and AWUS036AXER, DKMS install, WPA3 and monitor mode.
