Zyxel EX5601-TO wi-fi problem

Maurizio257

Good morning. I've been using the above-mentioned, unbranded router for about a year and a half. It worked perfectly until yesterday. Suddenly, the Wi-Fi service stopped working. After testing and checks, I discovered that the Wi-Fi is working, or at least reported as working, but at a very low power level, so much so that it can only be detected by placing a device near the router. A factory reset didn't help. I recently updated the firmware to V5.70(ACDZ.5.1)C0, but it worked as usual for two days. I think there's a hardware issue. I Need help. Thank you.
