Android USB tethering connects directly to a laptop via USB, not through a WiFi adapter. There’s no built-in speed limit for USB tethering, though performance depends on your device and connection quality. Most people assume it uses the same WiFi card, but USB tethering typically bypasses that hardware.
It relies on the phone's Wi-Fi adapter. The result varies based on your Wi-Fi speed and the USB port you're using. Using a USB 3.0 port would change that.
I used a phone Wi-Fi adapter since I assumed it worked the same as the laptop adapter. It can achieve up to 1 Gbps when I have mobile data and connect via USB 3.0 with my phone.
In theory yes, though there are several constraints, a) network traffic and connection priority, b) external interference, c) modem performance, d) connection protocols. Essentially your phone connects via Wi-Fi or mobile data, then routes through your USB link as an Ethernet link, and your computer treats it similarly to a wired Ethernet adapter or a USB-connected WiFi card.
The internet speed is influenced by the type of USB connection you use. For optimal performance, it's best to connect with USB 3.0 or Thunderbolt.
