Wi-Fi Network via Router Zyxel Keenetic 4G and M150-1 modem (Huawei E3276)
Answer
Hello. You have not written the main thing, what is the purpose? What kind of internet? Who should connect to whom? So, I can only guess.
If I understand correctly, you need to connect the Huawei E3276 modem to the USB port of Zyxel Keenetic 4G. Go to the router settings and configure it to connect to your operator. I can’t give you detailed advice here, as I don’t have a Keenetic 4G router. But it is not difficult and the Internet is full of instructions.
Also you will need to configure Wi-Fi network on the router. Change the network name from the factory and put a password.
If you have a bad signal, then to the modem M150-1 (Huawei E3276) connect the antenna “ULTRA 3G/4G” (if it fits the connector).
When the router Zyxel Keenetic 4G through the modem M150-1 will connect to the Internet, and will distribute it via Wi-Fi and cable, then on your computer (or whatever you have) you can connect the adapter TP-LINK TL-WN722N, install the driver on it, and connect to the Wi-Fi network, which will be distributed by your router.
I hope I understood you correctly and was able to help you.
