First, each new release does seem to slightly improve.
the R069 beta had great speed, but my iOS devices constantly dropped connection, so when I saw R070 was released, I quickly updated.
Now, iOS devices no longer drop connection, but speed seems worse overall.
Connections that were giving me between 4-6 megabyte (not megabit) per second, are now averaging between 800k and 1.5 megabyte per second.
Eagerly awaiting the next build in hopes of getting everything finally working at full speed.
