Justas,

The IEEE 802.11abg model does not support changing the emulator physical
layer frequency settings. You will have to modify them using physical
layer configuration. Use the center frequency of the channel of interest.

Only change the subid parameter if you want to use the same frequency
and mode for both networks. The subid effectively changes the waveform
from the emulator's perspective, causing the two networks to interfere
with each other in this case. Using different frequencies or modes does
not require different subid values in order to have two networks.
