Hello, developer. Do you have firmware for "tp-link WTA 301"? This is a China Telecom customized version.
no, we don't.
In the future, feel feee to search: https://openwrt.org/toh/views/toh_fwdownload
Given device is sold only in Chine (not Vietnam or India) best way to proceed is to ImmortalWrt - maybe the device is just alias for similar device sold internationally.
