There are no downloadable drivers for T4U Plus Hardware v1.8.

The only download for this model and hardware version combination is the user guide:

https://www.tp-link.com/baltic/support/download/archer-t4u-plus/v1.8/

There are many other hardware versions available. Are any of the other versions compatible with v1.8, or can you please provide the download location for v1.8.

Thanks,

Jake
