Hello,

I have recently purchased 4220 adapters. Everything works perfectly, wifi, speed.

But every x days, one of the adapters disappears from the network. Stop connecting the wifi and it is not accessible from the web configuration. The device is visible from the other receiver, but its speed is 0Mbps. This has already happened to me on both devices. Both devices are directly connected to plugs without going through power strips.

Your wifi is visible from but does not link to the adapter. I have to unplug it and plug it back in to make it accessible again.

After unplugging

Firmware is the one that brings the device from the factory.
