[Hostapd & Alfa AWUS036AC Wireless Adapter]

Hi, I'm trying to set up a wifi access point using an Alfa AWUS036AC Wireless Adapter. My hostapd.conf file is below. I am having three problems with the access point, and I believe they may be related. Any help is appreciated.

The three problems:

1. Network capture shuts down in the middle. Error: "network adapter on which the capture was being done is no longer running; the capture has stopped"

2. "Incorrect Password" error when the password is correct

3. Once connected to Mywifi, there is no internet available.

Hostapd.conf:

#hostapd.conf
interface=wlan0
driver=nl80211
ssid=Mywifi
channel=1
macaddr_acl=0
accept_mac_file=./allowed_macs
logger_syslog=-1
logger_syslog_level=2
wpa=2
wpa_passphrase=password1
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
rsn_pairwise=CCMP
