No, no changing.
Last time I went to Duma was 6 days ago to check the speed of one of my LAN cable.
PC was acting strange.
On Duma I discovered that Lan4 was down to (!!! 10m !!!)
then I changed a 25cm Cat6 cable.
It was new and faulty 😄
I rebooted 5 minutes ago.. the the router is not coming back.
I can write because Pc switched on Cell Wifi

UPD:
Rebooted twice and now I can access Duma again.
In the process I've lost the capacity to ping 8.8.8.8 dns.google !!!🙄
