Zeeb r15:7 > > I was excited to see that it looked like 802.11n was on the way! Tried step one, enabling 802.11 crypto, and had no luck at all. I know my AX211 supports CCMP, but attempting to boot gets: wlan0: link state changed to UP iwlwifi0: _lkpi_iv_key_set: CIPHER SUITE 0xfac02 (TKIP) not supported wlan0: link state changed to DOWN Why don't I see any attempt to do CCMP? Am I looking at an issue with the Arris WiFi provided by my carrier (Frontier)? I can't find any reference to encryption in the DHCP configuration. Mine is very basic PSK: network={ ssid="My BSS" psk="My key" priority=5 } After several tries at getting an address, it gives up and the system crashed. I have the text dump and will attach the crash message. Also have the full dmesg, if they are of use. I probably am simply missing something. Thanks! I enabled it is loader.conf, but the reboot failed to connect and then crashed. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkober...@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683
