A very basic question:

Background:

I just bought a couple of RE220s to extend the range of my wireless network. 

The 2.4 and 5 Ghz signals from the units are named as extensions of the main network:

Suppose the main network is named:

main

I append

_220_2.4 (for one RE220)

_220b_2.4 (for the other RE220)

for the 2.4 Ghz extended networks. Similarly for the 5 Ghz extended networks.

Should I expect the input network (main) to be boosted and emitted?

Or are only the extended networks - extended? 

Basically, should I just name all networks "main" to use it as a single network? 

Thanks,
