(solved with the update to kernel 4.9.9)

I have owned this adapter since Fedora 23, more than a year. It worked perfectly in F23 and F24 but with the OS version update to Fedora 25 the driver no longer compiles.
The source is from http://www.tplink.com/ie/support/download/?model=Archer+T4U&version=V1#tbl_a
(Archer_T4U_V1_150821)
with the line
{USB_DEVICE(0x2357, 0x0101),.driver_info = RTL8812}, /* TP-Link - T4U */
added into the
#ifdef CONFIG_RTL8812A#ifdef CONFIG_RTL8812A
section

Here is the result:
