My tablet has a SIM card that gets data over AT&T's cell network. Once the connection gets going it works great, but connecting to the network takes about 5 minutes. This is strange because it only takes a few seconds for the tablet to determine that it can detect the network at full strength; it just takes a long time for the little "H" to show up next to the signal-strength icon, at which point data exchange can occur.
What can I do to accelerate this? I'm running CyanogenMod on a Nexus 7 2012 tablet.
