Router Zyxel Keenetic 4G II. Bad signal, the Internet is unstable

Question: Hello, in this router inserted antenna-flash, the router is in a free room about 30 square meters. Internet is very unstable, then normal, then weak, then sometimes disappears. Question – how to strengthen the signal router? What do I need to buy an amplifier? Or is it still depends on the operator? Thank you.

Answer:

You wrote very little information about the problem. Do you have a bad Wi-Fi network signal, or just bad internet? I understand that Zyxel Keenetic 4G II router receives internet via 4G modem. So, most likely it is the poor 3G/4G signal. The modem just does not receive the signal well.

But, as I wrote before, the problem is not clear. If the Wi-Fi network level is good (it is displayed on the devices), then the problem is most likely in the signal from the operator. Perhaps you need to put an antenna for the modem.
