I have an MT7615 based wireless network adapter which apparently supports dual band concurrent mode. So how would I go about setting up two access points one on 2.4GHz frequency and another one on 5GHz using hostapd?
My current 2.4GHz hostapd config looks something like this:
ssid=XXX
interface=wlan0
hw_mode=g
channel=9
bridge=br0
driver=nl80211
logger_syslog=0
logger_syslog_level=0
wmm_enabled=1
wpa=2
preamble=1
wpa_psk=XXX
wpa_passphrase=XXX
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
auth_algs=1
macaddr_acl=0
ieee80211n=1
ht_capab=[SHORT-GI-20][SHORT-GI-40][HT40+]
country_code=XX
ieee80211d=1
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
