Firmware is 2.6.1.36 on RBR and 2.6.1.38 on RBS40.
Problem is that I have very strong 5 GHz and 2.4 GHz signal on RBR40 but only 2.4 GHz on RBS40. This was not the case when I installed it with older firmware.. I don't remember which one. Currently I see two 2.4 GHz signal and one hidden 2.4 GHz signal.. There is one 5 GHz signal on the RBR40. There are two hiddent 5 ghZ signal in a different channel. I have hard reset and enabled and disabled daisy chain, MIMO etc with no luck.. I am fairly senior networking engineer and still could not understand what's happening. After hard reset I see a feeble 5 GHz on RBS40 and after a while even that disappears..
