I believe it was showing red.
I also changed the channel and it has made a difference, thanks to those who suggested that.
I now have full strength everywhere in my house. Previously I lost a line in the bedroom, but everywhere else was fine. Now outside in my driveway I'm almost at full strength, but when I move to the yard I only have a line or two, but it still seems to stay connected whereas before I lost the connection completely. I was only out there briefly (it's freezing out today, lol) so I can't be sure it will stay connected. I'll test it better on a warmer day.
