Hi,
I am looking to upgrade my home connection from my bad wireless ISP (fastest i can get) to LTE connection.
I already have home network setup and its working. I want to replace ISP’s current (borrowed) antenna with “wAP ac LTE6” for LTE connection from new ISP and I would like to use it as outdoor WiFi AP for “grill place” which currently has poor to none signal 2,4g from inside.
My question: is it possible to have wAP ac LTE6 handle LTE connection and WiFi AP while all current setup (DHCP, FIREWALL, Routing,…) stays on my current main router.

I don’t need tutorials or other hints how to do it at this moment. I want to try to set it up myself later. Just is it possible or not.
