The network is probably just congested. When I had the One X, I would get around 20-60 down, 10-20 up. Depending on the time of day/night.
I'm outside of Tampa about 35 minutes northwest.
So my speeds on full signal and LTE are 5mb/s whats up with that?
I'm in Tampa and on ATT also. I usually get between 7 - 15MBps. I have occasionally been as low as 6. Have seen in excess of 22 though.
I flit about the Tampa-St. Petersburg area and so far I've seen 25 Mbps down/20 Mbps up in Dunedin (mid-morning) and 14.5 Mbps down/6 Mbps up in Tampa (early evening). I do think congestion factors into the results.
When we go to Spring Training every year I'm always impressed with how well AT&T performs there, Tampa/Clearwater/Orlando.
