Hello friends! I have the United States HTC One X+ running on AT&T. I'm having a problem where my phone will stay connected to my access point (Cisco AE4500), however after a while, my phone just won't transmit data anymore. It says its still connected, and I don't lose my IP Address lease, but whenever I try to use data after a period of about 20-30 minutes of idling, it just stop transmitting data. Toggling the connection resolves the issue, for a while at least. This happens on both the 2.4Ghz band, and the 5Ghz band. My phone is not rooted, running stock Jelly Bean (4.1.1). Any ideas? Thanks again.
