Still having problems streaming on Android.

[SoCalReviews]

Both 2.x and 4.x. Seems worse on 2.x. Guess I need to take it to the Androids! You do not think it could have to do with the AT&T modem in front on my Asus doing something that Android phones doesn't like?

Actually that could effect streaming. The AT&T modems and modem-gateways are notorious for these kinds of issues if they aren't set up properly to work with other routers plugged into them. I don't know what brand and model of AT&T modem you have but if you are plugging the Asus into that modem then put in in bridge mode or pseudo bridge mode... under the AT&T modem's settings put the Asus (MAC address) in the DMZplus mode. You can do a web search for the specifics of how to do this for your brand and model of AT&T modem or modem/gateway.
