changing channels of my 2.4 and 5 GHz networks

I have seen this question asked but not completly answered . . .

When you have an Xfi Mesh network (Xfi Gateway and Pods) can I change the channel management option from Manual to Automatic or if in Manual mode change the actual channel?

I am seeing in the router admin tool (not the Xfi app) that these options, Channel Mode and Channel selection are not accessible.

I followed Comcast instructions and named both the 2.4  and 5 GHz networks the same, do I have to break the mesh and rename one of the networks so they are diffrent to access the channel settings?

There is a note in some documents that states when Pods are connected to the Gateway then the channel management is automatic, but I do not think this is the case.  I have used a Wifi Analyser and it always show the 2.4 GHz channel as 1 and the 5 GHz channel as 157, these are the most common channels and the same channels that all of my nieghbors are on.

Any input or direction would be appreciated.
