same fiber optic modem Huawei router works but TP-Link AEX-75 does not work,
Good morning friends, I bought a new connection from Truck Telecom and they installed a Huawei LG8245x6 router but the wifi coverage is not enough for all rooms. I bought a new TP-Link AEX-7500 router from HK, I am trying to replace TP-Link AEX-7500 with Huawei LG8245x6 and connect the TP-Link AEX-7500 router with direct fiber optic modem, then the TP-Link AEX-7500 router red light start on, indicating that there is no internet connection, but the same Huawei router connected with same fiber optic modem is working but TP-Link does not work, I suspect I need to change a configuration parameter in the TP-Link router, any advice or guide lines?
