Witam

mam problem ze zrywaniem się połączenia internetowego, a dokładniej:
- dostawca to INEA (modem motorola sbv5121e), modem w trybie bridge
- router TPlink WDR-3600 (openwrt ) wan w klient dhcp

co może być przyczyną zrywania połączenia internetowego?
tymczasowo jako ominięcie problemu stosuję skrypt tester.sh który robi restart wanu, ale nurtuję mnie, dlaczego połączenie jest zrywane?

oto wycinek logów :
adresy ip i dns zastąpione xxx lub yyy
