I have not enjoyed the same level of connection stability for my 2.4 mobile client while working around the property, now and before I switched to using Smart Connect. TuneIn regularly stops streaming with a connection error when normally it does not. If feels like RC2-6 has a connection management issue.
Here's an abbreviated snip from the General Log:

I've made bold some suspicious entries... the first
D84:3C:0A:7A:A4 is a SONY AVR wired to the root node... the second
90:C78:90:85:59 is my 2.4 mobile client. There is only one weak 2.4 ch9 20MHz WiFi signal overlapping my ch11 signals.
