Hi there, LHGG LTE6 works like a charm even with default settings and successfully provide an internet via ethernet. is it possible to share it via cAP XL ac? What setting should be applied on both devices? Thanks

What exactly do you mean ?
Use cap xl ac as accesspoint on the network provided by LHGG LTE ?

Ofcourse that's possible.
Just configure xl-device as an access point.
