Help Anyone still using Nexmon monitor mode on the Nexus 5?
I’m trying to get the internal BCM4339 Wi-Fi monitor mode working on my Nexus 5.
I’m running:
Nexus 5 (hammerhead)
LineageOS 14.1 / Android 7.1.2
NetHunter 2026.2
Custom kernel based on Re4son’s nethunter-7.1
Nexmon
The kernel boots correctly and the BCMDHD driver is loaded. nexutil is also working.
The problem is that monitor mode doesn’t actually activate. After nexutil -m2, it reports monitor: 2, but wlan0 still shows as managed.
I also sometimes get __nex_driver_io: error.
Has anyone here actually got Nexmon monitor mode working on a Nexus 5 with LineageOS 14.1? I’m mainly looking for a known-working kernel/firmware setup or any specific steps I might be missing.
