Installing the correct driver is straightforward, but you must remove old remnants to avoid conflicts.

A: Yes. Go to Device Manager > Network Adapters > AC78X Properties > Driver tab > Roll Back Driver. If greyed out, run the installer for an older version (e.g., Version 4100).

The term "AC78X" refers to a family of wireless chipsets and adapters produced by Broadcom and licensed by Netgear. These drivers are most commonly associated with:

The "AC78X" nomenclature is often used in driver .inf files and developer documentation to represent a range of chipsets (e.g., BCM4378, BCM4352, etc.). Version 4300 is a specific firmware and software revision that addresses numerous bugs introduced in earlier builds while unlocking higher sustained data rates.

Current AC78X drivers (pre-4300) lack:

No, this is a Windows-based driver (.inf + .sys). Linux users need the brcmfmac kernel driver. However, Version 4300’s firmware blob can be extracted to improve Linux performance in some cases.

A: No. This driver package is strictly for Windows. Linux users will need to use the open-source rtl88x2bu driver (which is actually based on Version 4300’s source code).

In driver communities, "Top" signifies the most feature-complete, stable, and highest-performing release in a given version family—essentially the "final gold build" before Netgear moves to a new major version.
