Okay, I understand. I'm also still waiting for RC2-5 for my RT-AC5300. At the moment I can live with RC2-4. The nodes are already on RC2-5.@ginny + @det721 - thank you and yes I know, but as everyone else has seen there are several smaller issues and bigger issues with this beta (which is fine for a beta!) and if the issues with rt-ac88u codeline seems to be bigger and take more time before I can test rc5 and provide feedback, I would reset my wifi at home and go back to merlins latest official release.
Having the features of AiMesh2 is nice and try the beta of course too, but overall stability for example of 5Ghz and 2.4Ghz radio - lets call it the basic stuff - is even more important. You can imagine how much pressure you can get from two kids not having wifi (due to reboots ...), sometimes it feels like wifi is more important than having clean water to drink ;-).
