I have been having issues going over my allocated WiFi at home for the last several months. I assumed it was a problem on their (Exede's) end as the only things connected to our WiFi are our laptop and iPhones, and we don't use it much other then basic web browsing. We don't do online games or streaming videos or anything like that. The laptop gets put to sleep when not in use, and I have turned off the auto iCould backup on the iPhones (4 and 4S). The router constantly showed data being sent. No one else has our password, but just to try and figure out what was going on I changed the password today on our network and the only thing that had the new password was the laptop which I then shut down. No data is being sent now, so I can only assume its the iPhones. Any ideas on what I'm missing and why it would constantly be transmitting when on our WiFi? It doesn't seem to have this problem when on 3G as we don't use any data when on that according to Verizon, but we don't get 3G at our house so we are stuck connecting to the WiFi.
