Thanks, I figured it out. I had a couple things wrong. I didn't know i had to recompile crda with the keys generated when the regulatory database is compiled. I'm not sure if everything I did is correct / necessary, but it works. I ened up doing the following. # Compile regulatory database cd /usr/src/ git clone git://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git cd wireless-regdb/ make && make install #Compile CRDA , must use the keys generated by regulatory database cd /usr/src/ git clone git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/crda.git cp /usr/lib/crda/pubkeys/* /usr/src/crda/pubkeys/ make && make install #Setup up Regulatory Domain to US echo "REGDOMAIN=US" > /etc/default/crda echo "options cfg80211 ieee80211_regdom=US" > /etc/modprobe.d/cfg80211.conf iw reg set US # hostapd.conf file ctrl_interface=/var/run/hostapd ctrl_interface_group=wheel bridge=br0 interface=wlp4s0 driver=nl80211 hw_mode=a channel=0 auth_algs=1 ssid=Test-5ghz macaddr_acl=0 ignore_broadcast_ssid=0 ieee8021x=0 wme_enabled=1 ieee80211n=1 ht_capab=[HT40+][HT40-][SHORT-GI-40][TX-STBC][RX-STBC1][DSSS_CCK-40][SHORT-GI-20] vht_capab=[MAX-MPDU-11454][RXLDPC][SHORT-GI-80][TX-STBC-2BY1][RX-STBC-1] vht_oper_chwidth=1 vht_oper_centr_freq_seg0_idx=42 vht_oper_centr_freq_seg1_idx=159 country_code=US ieee80211d=1 ieee80211h=1 wpa=3 wpa_key_mgmt=WPA-PSK wpa_passphrase=password1 wpa_pairwise=TKIP rsn_pairwise=CCMP wpa_group_rekey=300 wpa_gmk_rekey=640 On Fri, Jun 30, 2017 at 3:14 AM, Zefir Kurtisi <zefir.kurtisi@xxxxxxxxxxx> wrote: > Hello Todd, > > On 06/26/2017 11:45 PM, Todd Lewis wrote: >> I'm setting up a access point on a linux router. >> I am unable to start hostapd.
