Hello
I was wondering if anyone knows how to setup an external antenna for LTE5388-M804. There is no user manual for this model on Zyxel homepage for some reason, and I can't find a single mention of external antenna in the administration of the router. Is it just to plug it in and it will switch from the internal antenna to the external automatically? Or am I missing something?
