Więc wracam z logami:
W chwili kiedy łącze WWAN padło i było OFFLINE, ping był taki:

Wystarczyło zrobić mwan3 ifup WWAN aby WWAN wrócił do żywych.
Co ciekawe, WWAN cały czas ma IP i działa, tylko routing się miesza. Jestem tego pewny, bo kiedy łącze główne WAN padło naprawdę , a potem padło WWAN ale tylko w statusie mwan3 to cały czas miałem zdalny dostęp do routera przez Zerotier.
