I am in Orlando as well and my radio is constantly switching to 3G when indoors. Sometimes not even to 3G and just shows that compus looking icon. Even if Im by a large window and can see I-4 and have a cell tower visible near by. My uploads and downloads are usually way off (at least it seems that way to me).
Example: My fastest download was 11.53mbps, but the upload speed for the same test was only 2.01mbps. Another recent test gave 13.00mbps download and only 1.98mbps upload. I know its all subjective to where I am in relation to the towers closest to me, but I have let to be "amazed" by the "blazing fast speed" the big Red advertizes. At least in the Orlando area, it has not been so wonderful. Outside I tend to stay connected for 4G.
Whats the typical speed I should be seeing?
I also notice if I close out of my Dophin web browser, I lose internet connectivity. I have to constantly go into my wireless settings and click the check mark for mobile network. If i stay in the browser the whole time it stays connected, If I get a text or want to multi-task, ill come back to the browser and it will state "no connection is available". Just thought Id see if this was normal or if others experience similar issues.
Aside from that, I love my TB.
