Recommendation for wireless mesh networks for reactors?

[Ryu79]

Just wondering if anyone has any recommendations/good experience with setting up/using a dedicated wireless mesh network dedicated for their reactors.  I am moving into a house and in my current setup I have my 2 x reactor 900’s connecting directly to my wireless internet modem which works fine.  However in my house I plan to have them in the basement and also I want to rmove the dependency of my wifi connection to my internet.  Ie. when my internet goes down I need to reboot my modem which results in my stereo pairing getting messed up.  Also I have a pair of golds + dialogue which I want to use a dedicated wifi network
