I have 2 SSIDs on wlan0:
config wifi-device 'radio0'
option type 'mac80211'
option channel '11'
option hwmode '11g'
option path 'pci0000:00/0000:00:01.0/0000:02:00.0'
option htmode 'HT20'
option legacy_rates '1'
option country 'GR'
config wifi-iface 'default_radio0'
option device 'radio0'
option mode 'ap'
option ssid 'home2'
option key 'xxxxxxxxxxx'
option network 'vlan1'
option encryption 'psk2'
option wds '1'
config wifi-iface
option device 'radio0'
option mode 'ap'
option ssid 'radius-test'
option encryption 'wpa2'
option auth_secret 'xxxxxxxxxxx'
option dynamic_vlan '2'
option vlan_tagged_interface 'eth0'
option vlan_bridge 'br-vlan'
option vlan_naming '0'
option auth_server '127.0.0.1'
When my client (D4:A3:DD:C9:CD:04) is connected to the first (WPA2 PSK) SSID:
iwinfo wlan0 assoclist
D4:A3:DD:C9:CD:04 -37 dBm / unknown (SNR -37) 10 ms ago
RX: 65.0 MBit/s, MCS 7, 20MHz 96 Pkts.
TX: 117.0 MBit/s, MCS 14, 20MHz 31 Pkts.
expected throughput: 43.4 MBit/s
00:27:22:9E:DD:D2 -39 dBm / unknown (SNR -39) 160 ms ago
RX: 58.5 MBit/s, MCS 6, 20MHz 608 Pkts.
TX: 58.5 MBit/s, MCS 6, 20MHz 1659 Pkts.
expected throughput: 20.5 MBit/s
When my client is connected to the second (WPA2 802.1X) SSID, I see only the other client:
iwinfo wlan0 assoclist
00:27:22:9E:DD:D2 -39 dBm / unknown (SNR -39) 150 ms ago
RX: 58.5 MBit/s, MCS 6, 20MHz 741 Pkts.
TX: 58.5 MBit/s, MCS 6, 20MHz 2114 Pkts.
expected throughput: 29.7 MBit/s
