Hi, i have 3 updated Neon linux. For each of these i have this problem:
I have a new router for fttc, when i connect my neon distributions on it wifi
work perfectly, speedtest ok 80mbps down 10 up, the problem appear only if i
use hight bandwith for long time (system update,huge file downloads, etc...)
wifi remain connected but the connection stop working and download after a
small period goes in timeout, ping to router's ip not responding but at the
same time i can navigate through it with Android cellpones and another pc
windows, seems that this problem appear only on neon.

If i disconnect wifi and reconnect to router connection work again until i use
again highter bandwith.

The only log related to wifi say:
