[kruger84]

0

To pozostaje zdiagnozować co się konkretnie "wywala":
- fizyczny link
- łącze do vpn
- łącze do Internetu
- coś innego

Po wywołaniu problemu przydadzą się wyniki poleceń:

Kod:

ip link

Kod:

ethtool nazwa_karty

Kod:

ping -c 4 8.8.8.8

Po wywołaniu powyższych komend dostaję coś takiego

Kod:
