I’ve converted my Asus PN40 mini pc into an openwrt router. Everything seems to be working fine. But since the pc has only one ethernet port I’m using a noname USB to ethernet converter as the second NIC for WAN. Is there a better solution? Are proper USB ethernet adapters a thing? Preferably with Intel chip?

Also i can’t get the PC’s intel 9000 series wireless chip to work in AP mode. I have hooked an old edimax repeater to the lan port as wifi AP but it’s a wireless N device.

Should i invest on a better AP? My ISP connection is capped at 300mbs. Can you recommend a cheap wifi 6 AP?

Also I have 2 internet connections.

Is it a good idea use the wifi in client mode, connect to the first internet through wifi and bond its internet connection with the wired wan?

Thanks for you help in advance.
