Some checks are pending
Build all core packages / Build all core packages for selected target (push) Waiting to run
WiFi 6E (802.11ax) clients cannot discover 6GHz APs operating at
320MHz because the HE Operation element contains uninitialized
center frequency values.
For EHT320 mode, the code sets eht_oper_centr_freq_seg0_idx but not
the corresponding HE values. Later, the HE values are copied from
VHT values, but VHT is not used on 6GHz, leaving he_oper_chwidth
and he_oper_centr_freq_seg0_idx at 0. This causes WiFi 6E clients
to see incorrect channel width information, making the AP invisible
to them during scanning.
Fix this by:
1. Setting he_oper_chwidth to 3 (160MHz) for EHT320 mode
2. Computing he_oper_centr_freq_seg0_idx based on the 160MHz segment
that contains the primary channel
3. Preserving these pre-set values instead of overwriting them with
uninitialized VHT values
WiFi 7 clients continue to see 320MHz operation via the EHT Operation
element, while WiFi 6E clients can now discover and connect at 160MHz.
