# g = IEEE 802.11g (2.4 GHz), ad = IEEE 802.11ad (60 GHz); a/g options are used
# with IEEE 802.11n (HT), too, to specify band). For IEEE 802.11ac (VHT), this
# needs to be set to hw_mode=a. When using ACS (see channel parameter), a
# special value "any" can be used to indicate that any support band can be used.
# This special case is currently supported only with drivers with which

Issue caused identified

Having both vht_oper_centr_freq_seg0_idx=42 and vht_oper_centr_freq_seg1_idx=159 set is causing the issue with hostapd-wpe.
