FreeBSD 14.3 Wireless Performance: Real Tests vs 14.2 and Arch Linux
FreeBSD 14.3 quietly shipped a big quality-of-life improvement for laptop and small-form-factor users: Wi-Fi performance. In this video and write-up I compare FreeBSD 14.2, FreeBSD 14.3, and Arch Linux on the same hardware and access point to see what actually changed.
TL;DR: 14.3 narrows the gap to Linux by a wide margin. If Wi-Fi performance put you off FreeBSD 14.2 on modern hardware, 14.3 is the update you’ve been waiting for.
Test Bench
-
Client: MeLE Quieter 4C Mini PC (Intel N150, 16 GB LPDDR5, 512 GB NVMe)
-
OSes: FreeBSD 14.2, FreeBSD 14.3, Arch Linux (KDE)
-
AP: UniFi UAP-AC-Lite (same SSID, channel, and distance for all tests)
-
Server: Wired host on the same LAN
-
Tooling:
iperf3for throughput; repeated runs per OS; same positioning and environment -
Displays/Drivers: Up to 4K@60 Hz verified on both Linux and Windows on this box; Wi-Fi 5 + BT 5.1 onboard
Methodology (Short & Fair)
-
Fresh boot into each OS, connect to the same 5 GHz SSID, confirm link rate and signal.
-
Run multiple
iperf3tests (downlink/uplink) against a wired LAN server. -
Discard outliers, average the middle results.
-
No changes to AP config between runs; device never moved.
Results at a Glance
-
Arch Linux: Baseline. Predictably solid Wi-Fi throughput and low jitter.
-
FreeBSD 14.2: Significantly behind Linux in raw throughput and stability on this hardware.
-
FreeBSD 14.3: Major jump in throughput and consistency versus 14.2, often landing much closer to Linux in my runs.
You’ll see the side-by-side plots and terminal captures in the video — the delta from 14.2 → 14.3 is the story.
What Changed in 14.3?
Without diving into every commit, the simple version is: newer wireless driver work and Wi-Fi stack refinements landed, which materially improve real-world performance on modern chipsets. On this Intel-based mini PC, that translated directly into higher, more stable iperf3 numbers.
Why This Matters
-
Laptops & SFF boxes: Fewer compromises when choosing FreeBSD for daily drivers or homelab nodes that rely on Wi-Fi.
-
AP-heavy environments: Better stability during roaming and under moderate interference.
-
“It just works” factor: Less tweaking needed to reach acceptable speeds.
Should You Upgrade?
If you’re on FreeBSD 14.2 and use Wi-Fi at all: yes — upgrade to 14.3. The improvement was obvious on my test bench, and it costs you nothing but a standard update cycle.
How I’d Update (High Level)
Always back up first.
-
Update to 14.3 via
freebsd-update(RELEASE → latest patch level). -
Reboot, verify interface names and connection, then re-run your usual workloads.
-
Optional: test with
iperf3against a wired host to confirm your own gains.
Arch Linux as a Reference Point
Linux still tends to get wireless driver updates first, so I keep it in the mix as a reality check. In these tests, Arch provided the expected top-end numbers — but 14.3 closed the gap dramatically compared to 14.2. That’s the headline.
Full Test Setup & Notes
-
Distance to AP: ~same spot on the desk for all runs
-
Band: 5 GHz, WPA2/WPA3 as configured on the AP (unchanged between runs)
-
Server: Gigabit-wired; no bandwidth bottlenecks upstream
-
Client power: Mains; no power-saving overrides applied
-
Repeated runs to smooth out transient noise

Conclusion
FreeBSD 14.3 delivers a meaningful, real-world Wi-Fi upgrade. On the MeLE Quieter 4C, it turned a “usable but lagging” wireless experience into one I’d actually recommend for light desktop use, homelabs, and portable toolkits. If you bounced off FreeBSD Wi-Fi before, it’s worth another go.
