There is only one tower around here. 3/4 mile away as the crow flies. The next tower is about 3-1/2 miles away in the other direction. I've optimized the connection as best I can to the nearer one. As best I can tell, I never see the other one from any window in it's direction. Once I got it to the best spot, I haven't moved it. The changing WAN IPs that I am speaking of has been since I located it properly.
Speed is about all I could hope for with 4G. No complaints there. It is a dumb modem/router, no doubt about it. I've got just enough skills to get past it's limitations for all of my junk around here. I wish I could have changed it's LAN IP, but it is what it is. It's funny how I kept having to think, "Oh that's right, I've still got xxxx that needs a new IP to work"...
The only take away is that I don't have the skills to be able to get BI viewable when I'm out and about. It's probably doable, but if it is, I've got some more learning to do.
Impressions so far? Heck, I went from about 5/.5 to around 60/12. Thus far (please don't jinx myself!), it's been a solid connection. So, what's not to like in that respect? We'll give it a few weeks and see.
