Zyxel T56 loses internet and WLAN after few minutes of use, makes buzzing sound Hi, I have been using Odido fiber for two months without problems, but the last few days, this keeps happening: Router is switched on. Everything works ok. 2.5G WAN, Internet, 2.4G, 5G lights all green. After few minutes of regular internet use, the router disappears from the wi-fi connection list in all devices. Only the 2.5G WAN and 2.4G lights are green. Internet and 5G lights are off. The router makes a low buzzing sound, which wasn’t the case when it was working fine. The Huawei ONT that the router is connected to has PON and LAN lights green during all this. There are no repeaters etc connected to the router, and max 3-4 devices have wi-fi connections at the same time. What can be the problem with the router here? Thanks!
