Yes, the Reolink Argus 4 Pro supports dual-band Wi-Fi 6 on both 2.4 GHz and 5 GHz. As a Reolink solar camera, this makes it one of the few battery-powered cameras with Wi-Fi 6. Here is what that means for your 4K live stream and connection stability.
Does the Reolink Argus 4 Pro Support Wi-Fi 6?
Yes. The Reolink Argus 4 Pro supports Wi-Fi 6 (802.11ax) on both the 2.4 GHz and 5 GHz bands. This makes it one of the very few battery-powered security cameras and one of the only Reolink solar camera models to include Wi-Fi 6 connectivity.
For most buyers, this means smoother 4K live streaming, a more stable connection on busy home networks, and better long-term compatibility as Wi-Fi 6 routers become the standard. This article explains exactly what Wi-Fi 6 does on the Argus 4 Pro and why it matters.
What Is Wi-Fi 6 and Why Does It Matter for the Reolink Argus 4 Pro?
Wi-Fi 6, also known as 802.11ax, is the sixth generation of Wi-Fi technology. It succeeds Wi-Fi 5 (802.11ac) and was designed specifically to handle the demands of modern homes and networks where dozens of devices are connected simultaneously, smart TVs, phones, laptops, smart speakers, and increasingly, security cameras.
For a 4K security camera like the Reolink Argus 4 Pro, Wi-Fi 6 matters in three specific ways:
- Higher throughput means more bandwidth available to stream 4K video without buffering or frame drops.
- Lower latency, faster response when opening a live view or receiving a motion alert notification.
- Better performance on congested networks, Wi-Fi 6 handles multiple simultaneous device connections far more efficiently than older standards.
Dual-Band Wi-Fi 6 on the Reolink Argus 4 Pro: 2.4 GHz vs 5 GHz
The Reolink Argus 4 Pro supports both the 2.4 GHz and 5 GHz frequency bands under Wi-Fi 6. These two bands serve different purposes, and understanding the difference helps you place the camera correctly.
2.4 GHz Band
The 2.4 GHz band offers a longer wireless range and better penetration through walls and obstacles. It is the right choice when the Argus 4 Pro is installed further from your router, such as at the rear of a property, a detached garage, or a garden gate. The trade-off is a slightly lower maximum speed compared to 5 GHz.
5 GHz Band
The 5 GHz band offers significantly faster speeds and lower interference, but at a shorter range. It is the better option when the camera is installed within a clear line of sight of your router, such as near a front door, on a porch directly adjacent to the house, or in a location where the router signal is strong. For streaming 4K video with maximum stability, 5 GHz is the preferred band where the signal allows.
Wi-Fi 6 vs Wi-Fi 5 vs Wi-Fi 4: How the Reolink Argus 4 Pro Compares
Here is how Wi-Fi 6, as used in the Reolink Argus 4 Pro, compares to older Wi-Fi standards found in other security cameras:
| Feature | Wi-Fi 4 | Wi-Fi 5 | Wi-Fi 6 (Argus 4 Pro) |
| Wi-Fi Standard | Wi-Fi 4 (802.11n) | Wi-Fi 5 (802.11ac) | Wi-Fi 6 (802.11ax) Argus 4 Pro |
| Max Speed | Up to 600 Mbps | Up to 3.5 Gbps | Up to 9.6 Gbps |
| Frequency Bands | 2.4 GHz only | 2.4 GHz + 5 GHz | 2.4 GHz + 5 GHz (dual-band) |
| Congested Networks | Poor performance | Moderate performance | Strong performance (OFDMA) |
| Latency | Higher | Moderate | Lower |
| Battery Efficiency | Standard | Standard | Improved (TWT technology) |
| 4K Streaming | Unreliable | Generally adequate | Smooth and stable |
Most battery-powered security cameras, including many Reolink solar camera models, use Wi-Fi 5 or even Wi-Fi 4. The Argus 4 Pro’s Wi-Fi 6 support is a genuine differentiator, particularly for homes with congested networks or multiple 4K streams running simultaneously.
OFDMA: Why the Reolink Argus 4 Pro Handles Busy Networks Better
One of the key technologies inside Wi-Fi 6 is OFDMA, Orthogonal Frequency Division Multiple Access. In plain terms, OFDMA allows a Wi-Fi 6 router to communicate with multiple devices at the same time within a single transmission, rather than taking turns with each device one at a time as older Wi-Fi standards do.
For a home with many connected devices, this is significant. On a Wi-Fi 5 or Wi-Fi 4 network with 20 or 30 devices connected, each device has to wait its turn to transmit and receive data. This creates congestion, which shows up as buffering, delayed live views, and dropped motion alerts from security cameras.
On a Wi-Fi 6 network, the Reolink Argus 4 Pro benefits from OFDMA by receiving a dedicated slice of bandwidth even when the network is busy, reducing the congestion effect and keeping the 4K stream stable.
Wi-Fi 6 and Battery Life on This Reolink Solar Camera
Wi-Fi 6 also introduces a technology called Target Wake Time (TWT). TWT allows the router and the camera to agree in advance on specific times when the camera’s Wi-Fi radio will be active, rather than keeping the radio on constantly listening for data.
For a battery-powered device like the Reolink Argus 4 Pro, TWT reduces the amount of time the Wi-Fi radio draws power while the camera is idle between motion events. This, alongside the removal of IR LEDs to the Argus 4 Pro, has improved battery efficiency compared to previous Reolink solar camera generations.
In practical terms, this means the camera’s 5000 mAh battery lasts longer between charges, and when paired with the Reolink Solar Panel 2, the solar trickle-charge is more likely to offset daily consumption fully.
Do You Need a Wi-Fi 6 Router to Use the Reolink Argus 4 Pro?
No. The Reolink Argus 4 Pro is fully backward compatible with Wi-Fi 5 and Wi-Fi 4 routers. If your current router does not support Wi-Fi 6, the camera will connect and function normally; you simply will not benefit from the Wi-Fi 6-specific improvements like OFDMA and TWT.
However, if you are buying a new router or already have a Wi-Fi 6 router, which is now standard on most routers sold after 2020, the Argus 4 Pro will take full advantage of the connection automatically. No additional configuration is required beyond connecting to your network as normal through the Reolink app.
How Does Wi-Fi 6 Set the Reolink Argus 4 Pro Apart from Other Reolink Solar Camera Models?
Within the Reolink solar camera range, Wi-Fi 6 is not standard. Most Reolink solar cameras,s including the Argus 3 Pro and the standard Argus 4, use Wi-Fi 5 connectivity. The Argus 4 Pro is currently one of the only models in the Reolink lineup to offer Wi-Fi 6 dual-band support.
This means that for buyers specifically prioritising connectivity performance, particularly those with large homes, thick walls, crowded networks, or existing Wi-Fi 6 infrastructure, the Argus 4 Pro is the strongest choice in the Reolink solar camera range.
Frequently Asked Questions
Does the Reolink Argus 4 Pro work on 2.4 GHz Wi-Fi?
Yes. The Argus 4 Pro supports dual-band Wi-Fi 6 on both 2.4 GHz and 5 GHz. You can connect to whichever band suits your installation: 2.4 GHz for longer range, 5 GHz for faster speeds.
Does the Reolink Argus 4 Pro require a Wi-Fi 6 router?
No. The camera is backward compatible with Wi-Fi 5 and Wi-Fi 4 routers. A Wi-Fi 6 router is not required, but is recommended to get the full benefit of OFDMA and TWT features.
Will the Reolink Argus 4 Pro work on a crowded Wi-Fi network?
Better than most battery cameras. The Wi-Fi 6 OFDMA technology allows the camera to receive dedicated bandwidth even when many devices are connected simultaneously, reducing the buffering and connection drops common on congested Wi-Fi 5 networks.
Does Wi-Fi 6 improve battery life on the Reolink Argus 4 Pro?
Yes. Wi-Fi 6 includes Target Wake Time (TWT), which reduces how often the camera’s Wi-Fi radio needs to be active when idle, lowering standby power consumption and contributing to longer battery life.
Which Reolink solar camera models support Wi-Fi 6?
As of 2025, the Reolink Argus 4 Pro is one of the only Reolink solar camera models to support Wi-Fi 6. Most other models in the Reolink solar camera lineup, including the Argus 3 Pro and Argus 4, use Wi-Fi 5.
Conclusion
The Reolink Argus 4 Pro does support Wi-Fi 6, on both the 2.4 GHz and 5 GHz bands, and it is one of the only Reolink solar camera models to do so. The practical benefits are real: smoother 4K streaming, lower latency on live view, better performance on congested networks through OFDMA, and a small but genuine improvement in battery efficiency through TWT.
You do not need a Wi-Fi 6 router to use the camera, but if you already have one or are planning an upgrade, the Argus 4 Pro is built to make full use of it. For buyers comparing Reolink solar camera options where connectivity is a priority, Wi-Fi 6 is one of the clearest technical advantages the Argus 4 Pro holds over the rest of the range.
