[Avinash1992]

Hi Team, 

We are using kernel's 6.1.36 Intel Ax210 wifi driver, we configured the device in Access point (hostapd-2g attached) mode with 2.4 GHz band and WIFI 6 protocol and when we tried to connect this AP device to STA, we observed the crash in iwlwifi /iwlmvm (driver crashlog attached).

Hi Jose, 

Can we use 6.6.8 kernel version driver for AX210, version is stable. also, do we also need cfg80211 module, in order to enable wifi 6 capabilities?

Avi
