Hi @fdamaral, good that you are sounding the alarm for this.

I immediately went to check for you and did a line measurement. Here you can see some attenuation on the Media Converter. I also see that the modem has been online for over four weeks. Could you also power it down for 30 seconds and reboot it just to be sure? If it is still not stable after that, please let me know. I will then investigate it for you! 

Hi! I just got up, sorry.

Since I woke up and turned my computer on 20 min ago it's been working. It worked after I reset the fiber modem (just the fiber part, not the router, which was functioning normally all the time as my local network was ok, including a few dozen smart home devices cameras etc).

I only opened this topic because it felt the network (outside) could be unstable, so you'd be aware of it.

I really appreciate your quick answer.

Thanks for letting us know @fdamaral! Wishing you a good evening.
