no bars. never any bars.

So I noticed that I never get more than like half a bar at home, and they sent me a hub to put in. That's working fine, and the bandwidth is plenty, but I still never have any bars. And it's not just at home, it's pretty much everywhere. 4g is working just fine. Anyone know of a tweak or custom modem that fixes this? I'm missing calls sometimes it's so bad.

Thanks!
