I tried before on Redmi Note 8 on Android 9 with Type C. Once you connect the adapter it will automatically recognize the USB lan only if you have a LAN cable attached.
Problem is there are no settings like IP or DNS that you can change. You can only view the status of the adapter that is working on the notification bar. You will get whatever fastest speed you have on the gigabit ethernet. In this case my house is 300Mbps, the speedtest is around 2xxMbps.

There are also certain limitation like minimum version of android that supports this. The site below says Andorid ver 6.

So you have to do a little study on the phone and tablet that you intend to use it on.

i do not know if this TPLINK UE-300C USB adapter will work if you use a Type C to Micro USB converter.

The thing is, the USB adapter is not even documented to work with Android. But i saw in manual it supports Chrome OS. So maybe Chrome OS = Android.

Plug it into phone and it works!!! But cannot config it. Yes its probably supported hardware that is baked into OS prior to release. It costs TS less than RM 100 to try anyway.

You can't. The phone does not have DHCP server. At most it can work as a tether modem.
