Advantages:
- The establishment of the router was very easy.
- The built-in LTE antenna has better reception than my Smamsung S4 Mini smartphone.
- With Telekom Mobile Data @ home you can get an external IP and DynDNS can access the home network without problems (after release of the ports in the router).
Disadvantages:
- The Wi-Fi reception is not very good. Since I'm used to from my old Netgear router better.
