I have a Raspberry Pi 4b 4GB with Openwrt and WireGuard Client installed on it. I am using it as a vpn travel router to connect to my home network. My computer is connected via ethernet to the Pi and the Pi is connected via wireless to a another wifi network to get access to the internet. But the wifi speeds of the pi are really slow. (50Mbps up and down)
Can anyone recommend a fast usb wireless adapter that is supported?
What I have found so far are these two. But they still only have speeds of 600Mbps
