I have just this fun kind of unpredictability in my router's 4G module. Mostly, it comes up as wwan0 but sometimes it's wwx<random>. So I put something in my 4G management script to rename such interface if there's no wwan0. Easier to force the interface name since I need to know the interface in the firewall and failover script too.
