Very nice 4G router. User-friendly, fast, versatile, easily adjustable, with guest network, great!

A disadvantage is that 4G router does NOT have a fixed IP address (that applies of course to all 4G routers). That's because your telecom provider has some kind of internal network (CG-NAT, Carrier Grade NAT). This makes it impossible to access the router from outside. So you can't do port forwarding to reach an IPcam or NAS, for example. Maybe this will work with a VPN, I haven't tried that yet. Incidentally, many IPcam brands offer a cloud service (such as Foscam or Ezviz) through which you can reach the camera, for example via their app.

For the rest it is a very nice WiFi router. p.s. There are a few telecom providers that do provide a fixed IP address with 4G, such as T-mobile for the home or KPN rural areas. But sometimes there are other conditions attached to this.

Very good router if you don't have a cable network, very convenient to use
