is a wifi ac adapter speed affected by usb 2 vs usb 3

Some manufacturers also restrict certain operating modes depending on the type of cable and/or charger that you use. Just remember that USB-C doesn’t automatically specify any kind of performance level in and of itself. USB-C, USB 3.2 Aren’t Always Hooked Together wireless-n can give you 300 Mbps, for CAT-6 you can get a theoretical 10 Gbps. Combine a non-standard vendor implementation with a non-standard cable manufacturer implementation, and what you get is a recipe for trouble (and dead hardware). This is used to pick up the signals from your wireless router. Some major companies, like Nintendo, have built their own non-standard USB-C implementations. With most USB WiFi adapters you will have an antenna built into the stick itself. Look for brands specifically marketed as compatible with your device, stick to well-known products, and honestly, I’d check online before buying a USB-C cable for anything you care about. My own approach to this problem would be to look for a new dongle with a good reputation for throughput to eliminate the dongle as the bottleneck.It is in your best interest to always use the USB-C cable provided by the device manufacturer, and never to buy a replacement cable assuming that any old brand will do. You can research this online for your OS/dongle combination. It is also possible that changes to the system’s parameters for the TCP/IP stack could make improvements. Depending on the driver, there may be options to tune the parameters used by the driver to run the dongle. One more place you might be able to improve things is in the driver configuration. If you choose to buy a new dongle, check reviews for good throughput, they are not all created equal.

You can check for updates for the soft parts of this, and, of course you can replace the hardware in this case.

Similarly, it could be the implementation of the dongle hardware, firmware, or driver. You can check for firmware updates, and that might just help, but of course you can‘t do anything about the hardware.

Even though the standard can support the higher rate, the hardware or firmware for the port could be limiting throughput. It could be the implementation of the USB port. The standard for USB 2.0 provides up to 280mbps, far more than you need for this application. To add a different version of mostly the same answer as others have given:
