I work in a large building that uses repeaters to help boost signal through the building. They took the system down over the weekend for repairs and an upgrade. I always got good enough signal throughout the building, sometimes it would bounce between 3g and 1x, but I could make calls and got data fast enough. After this upgrade/repair, I'm seeing slightly better signal displayed but I can't make any phone calls or use data. I have 3 bars with the green 3g but as soon as I try to make a call it drops. I can't get the web to load or use any apps that need a data connection. I thought repeaters just boosted the signal so I don't get how my phone can get signal but not be able to use it. Is there a setting on my phone I need to check? I'm running 2.3.5 Thanks
