Fix (unique to 4.3.00): Open Netgear Genie (or adapter properties) → Advanced → Transmit Power → Set to 100%. Some 4.3.00 builds default to 75%.
Yes. The driver includes an official WHQL signature. Check the “Digital Signatures” tab in driver properties.
To conclude, version 4.3.00 remains a highly competent, battle-tested driver for the AC78X adapter family. It trades some modern protocol optimizations for rock-solid reliability, lower latency, and predictable behavior under load. If you rely on your Netgear adapter for daily work, streaming, or competitive gaming, and you value consistency over absolute peak throughput, 4.3.00 is arguably the best driver you can install.
However, bleeding-edge users with Windows 11 and WPA3-Enterprise networks should consider newer builds. Always keep a backup of the 4.3.00 installer so you can quickly fall back if the latest driver causes issues.
Remember to download only from trusted sources, verify your hardware model, and tailor the advanced Wi-Fi settings to your environment. A correctly configured AC78X adapter running driver version 4.3.00 can easily outlast many built-in laptop Wi-Fi cards, delivering multi-year, drop-free service.
