Mark, I fully understnad your concern. To clarify for others, the 2.4-RC1 release does solve these issues, but I assume you are waiting for the stable release.
The releases for B3 in between are all being part of the 2.4 stable release, it's just pre-releases to fix issues before the major release. The corresponding "in-between-release" thing for B2 is actually this 2.4-RC1 release, which fixes the wifi issue but since this is such a major change, it also brought along some new bugs, which is why we had to release it as a RC, not stable.
Rest assured we are working with the stable 2.4 on high proiority. I'll keep you posted.
