I have an issue with Smart Connect on the MR 600. I have to set the 2.4G channel to channel 11 manually as my neighbours use either channel 1 and 6 . I have an RE200 Mesh extender and I'm able to One Mesh with the MR600 without any problem . There is a tip to use Smart Connect to better improve the switching speed between the wifi bands. If I switch on Smart Connect it works but changes my 2.4G Channel 11 to Channel 2 or 4 automatically and places me with high interference from my neighbour. Of Course if I switch it off I can go back to channel 11 .Is Smart Connect meant to work this way? Surely I should be able to select the channel I want! . What is the most up to date beta or official firmware  I should use. I also have the sms issue where I cant read messages
