** Description changed:
>Problem: error `ERROR @wl_set_key_mgmt : invalid cipher group
(1027076)`
- Logic errors in error-reporting code cause a highly misleading message
- to be emitted. The problem is not within cipher group (that is supported
- WLAN_CIPHER_SUITE_CCMP).
+ 1. Logic errors in error-reporting code cause a highly misleading
+ message to be emitted. The problem is not within cipher group (that is
+ supported WLAN_CIPHER_SUITE_CCMP).
```patch
- WL_ERR(("invalid cipher group (%d)\n",
sme->crypto.cipher_group));
+ WL_ERR(("invalid akm suite (%d)\n",
sme->crypto.akm_suites[0]));
```
+
+ 2. Once we fix the error-reporting logic we get the correct error
+ message:
+
+ > ERROR @wl_set_key_mgmt : invalid akm suite (1027078)
+
+ It is because that case (WLAN_AKM_SUITE_PSK_SHA256) is not processed.
+ Even the mere presence of it in announced cipher suites is enough to
+ break wifi. Not only for this driver, but also for drivers for Windows.
+
+ I have ported processing of the cases from the open-source driver, but
+ it still doesn't work and causes errors in kernel. Likely it requires
+ some code in other places, maybe even in firmware.
+
+ `wpa_key_mgmt=WPA-PSK WPA-PSK-SHA256` in `hostapd` config (currently it
+ is defaults on OpenWRT).
+
+ The OpenWRT wiki is incorrect, in `/etc/config/wireless` `ieee80211w=1`
+ is the default, which causes `wpa_key_mgmt` be generated so.
+
+ `wpa_key_mgmt=WPA-PSK SAE` in `hostapd` config works fine (if these
+ shitty crashing drivers can be called working fine).
+
+ To make it so, explicitly set `ieee80211w=0` in `/etc/config/wireless`.
+
+ So the second patch just gives the explanination to the user what
+ happens and the instructions on what to fix in his router configuration
+ as a workaround.
