Something about gEnableApProt states about n.

Hopefully someone is wiser and braver than me to know more about this file and changes which may enable 5ghz.

# Valid values 0-128
# 128 means disable Energy Detect feature
# 0-9 are threshold code and 7 is recommended value from system if feature is to be enabled.
# 10-128 are reserved.
# The EDET threshold mapping is as follows in 3dB step:
# 0 = -60 dBm
# 1 = -63 dBm
# 2 = -66 dBm
# ...
# 7 = -81 dBm
# 8 = -84 dBm
# 9 = -87 dBm
# Note: Any of these settings are valid. Setting 0 would yield the highest power saving (in a noisy environment) at the cost of more range. The range impact is approximately #calculated as:
#
# Range Loss (dB) = EDET threshold level (dBm) + 97 dBm.
