Hi,

Whether your mobile phone will recognize a certain USB Ethernet adapter or not depends solely on which drivers the phone manufacturer has included in the phone's operating system. There is nothing TP-Link could do about that.

I can't say anything about iPhone devices, but on Android phones the success rate depends largely on the chipset used in the Ethernet adapter.

According to the TP-Link product webpage there are two versions of the UE300C. V1 and V2.

As you can see via the links above the V1 uses a Realtek RTL8153 chip and V2 uses an ASIX AX88179A chip.

From personal experience I can tell you that out of five smartphones I've owned in recent years only a single one of them can recognize an Ethernet adapter with the RTL8153 chip.

The success rate with Ethernet adapters using Asix chips is usually higher, but still there is no guarantee that it works. It really comes down to luck.

My doubt is cleared now. Thank You so much for your reply. I understand that the Internet from mobile to Wi-Fi router works using ethernet sharing. But, the real problem is choosing the correct USB-C Type Ethernet Adapter that works with my TP-Link Archer AX1500.

Do you suggest any USB Type C Ethernet Adapter that works with the AX1500 router? I am thinking about Amkette Super-Speed USB 3.0 + Type-C to RJ45 Gigabit Ethernet Adapter but which chip is there in this Adapter is not known. If you have any idea which company and model of its adapter work with tp-link routers, please suggest a few.

To reiterate, the problem here is whether or not the mobile phone supports (i.e. recognizes) the USB Ethernet Adapter.

This has nothing to do with the TP-Link Archer AX1500.

I've OnePlus 11R and 12 devices. Did you test with any adapter on this devices or other models of the same company? Posting a query on OnePlus community will help?
