Do you think its possible to change wifi channels (6 for 2.4ghz and 40 for 5ghz)? Thanks!

Yes, It's possible. First of all, connect all your nodes with your current configuration, it's necessary change at the same time all the nodes. (This is because, I don't know what is the node secundary's (MW5s in my case) IP default addresses). First, you have to hold Reset button three seconds for enabling Telnet (I tested this with MW5 and MW5s), Then, connect through Telnet (For example by PuTTY):

Then, you will have access to yours nodes. If you want to check you current settings, enter this command: cfm get ^ It will show you all avalaibles settings. Otherwise, you should be interested about settings which they start by:

This settings are:

The settings marked above they are the ones that I tried.

The way for changing the settings is: cfm set _settingname value For example: cfm set wl5g.public.channel 44

Try them and good luck! Thanks for all your work latonita!
