For what it's worth, my experience with the 2+ is that it seems to have a slow wifi connection, more precisely it doesn't seem to have a very powerful tx/rx. It was actually causing my wifi AP (Ubiquiti) to switch down to half duplex due to the error rate. I moved the device within a metre of the AP and all my issues were solved.
You may argue that my wifi AP was at fault but I tested on 3 different AP on my network and on a totally different wifi network at my office across town. If I monitor the wifi AP it will randomly switch to half duplex. If switch off the Omega, the AP will never switch to half duplex.
