To determine which firmware is "better" for you, check your usage:
Score for Official Netgear Firmware: 7/10 (Stable but bloated) Score for Voxel Firmware: 9/10 (Lean, fast, and powerful, but lacks Smart Connect)
Beta testers have reported that version 2.50 (due Q4 2025) will include: wlwn523n2 firmware better
Conclusion: The development cycle for WLWN523N2 is still active. Staying on old firmware means missing these cutting-edge improvements.
The WLWN523N2 supports 2x2 MIMO (Multiple Input Multiple Output), but many stock drivers run it in "legacy" mode for stability. A better firmware unlocks aggressive MIMO settings, improving spatial stream separation. Users report a 15-25% increase in range and a more stable connection at the edge of coverage.

Best for: General users, gamers, and streaming.
For years, the R7900P suffered from a reputation for instability on early firmware versions (V1.2.x and V1.3.x). However, the recent V1.4.x branch has largely stabilized the device. Score for Official Netgear Firmware: 7/10 (Stable but

Review Conclusion: If you want the router to "just work" with minimal fuss, update to the latest official firmware (V1.4.4.94 or newer as of late 2024) and leave it. The Smart Connect functionality is superior here compared to open-source implementations.
One of the silent killers of the WLWN523N2 is bufferbloat—the tendency of the device to queue too many packets during high load, causing massive latency. Better firmware replaces the standard FIFO (First In, First Out) queue with FQ-CoDel or CAKE algorithms. In practical terms, this means you can saturate your 100Mbps link with a download while still having a lag-free video call. Latency under load drops from 500ms+ to under 10ms.
