please login the TP-link , check if it can search the HUAWEI WiFi and connect it by bridge , if it cannot search the HUAWEI WiFi and connect it by bridge , you have to set the TP-link as a router or set it as bridge , and set the wifi SSID ,password manually in the TP-link device . or Change the TP-Link router to HUAWEI ONT compatible AP.
Thanks !
