Hello,

Is it possible for one station to get multiple ip addresses from AP/Wireless router by dhcp? I had tried to add one or more virtual interface for phy0 (wlan0, wlan1, wlan2,etc), but only wlan0 can get ip address from AP. the following is the steps:

/bin/wpa_supplicant -ddd -iwlan0 -Dnl80211 -c/wifi/wpa_supplicant.conf -B /bin/wpa_cli -i wlan0 -p /wlan0

Quoted 4 lines

add_network
set_network 0 ssid "APabc"
set_network 0 psk "1111111"
enable_network 0

iw wlan0 interface add wlan1 type station 4addr on ip link set wlan1 up
dhcpcd -ABKL wlan0 #works, can get ip dhcpcd -ABKL wlan1 #cannot work

Virtual stations work just fine for me, though I don't use that '4addr' thing. ...maybe sniff your wlan1 and see if it is sending
out proper DHCP requests (and they are being received by the AP)?

You have to create a new supplicant config for each virtual station, or run a unique supplicant instance for each station.

To do any useful traffic, between stations, you will have to be careful about setting up routing rules and use special binding commands for your traffic types.

Thanks,
Ben

You have to create a new supplicant config for each virtual station, or run a unique supplicant instance for each station.

I try to follow the instruction which you give and do the following command, but wlan1 cannot associate with AP.

1. root@local# /bin/wpa_supplicant -ddd -iwlan0 -Dnl80211 -c/wifi/wpa_supplicant.conf -B
2. root@local# iw wlan0 interface add wlan1 type station
3. root@local# /bin/wpa_supplicant -ddd -iwlan1 -Dnl80211 -c/wifi/wpa_supplicant_wlan1.conf -B

wpa_supplicant_wlan1.conf file contains folliwng lines:

ctrl_interface=wlan1 driver_param=use_multi_chan_concurrent=1 update_config=1
config_methods=physical_display virtual_push_button keypad

After this step, when using ifconfig, "ifconfig wlan1" gave a unusual hwaddr, is it a issue? ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:13:0B:D2:2D:B1
inet6 addr: fe80::213:bff:fed2:2db1/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

ifconfig wlan1
wlan1 Link encap:Ethernet HWaddr 02:00:00:00:00:00
inet6 addr: fe80::ff:fe00:0/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1

4. root@local# /system/bin/wpa_cli -i wlan0 -p /wlan0

Quoted 4 lines

add_network
set_network 2 ssid "APabc"
set_network 2 psk "11111111"
enable_network 2

wlan0 can associate with ap.

5. root@local# /bin/wpa_cli -i wlan1 -p /wlan1

Quoted 4 lines

add_network
set_network 0 ssid "APabc"
set_network 0 psk "11111111"
enable_network 0

it will give the following result:
<3>CTRL-EVENT-STATE-CHANGE id=-1 state=3 BSSID=00:00:00:00:00:00 SSID= <3>CTRL-EVENT-SCAN-RESULTS
<3>Trying to associate with 78:f5:fd:77:e5:a4 (SSID='APabc' freq=2462 MHz) <3>CTRL-EVENT-STATE-CHANGE id=-1 state=5 BSSID=00:00:00:00:00:00 SSID= <3>CTRL-EVENT-ASSOC-REJECT status_code=1

so wlan1 cannot associate with ap.

further help is appreciated, thanks.

What driver are you using? I'm not sure anything other than ath9k can do this feature. Ath5k probably works, and definitely worked at one time. Ath10k supports this to some degree, and will have more support in the future.

You typically have to disable hardware crypt to make this work.

Thanks,
Ben

I use bcm4329 chipset and it don't have "Disable HW encryption" options. any suggestion for this is appreciated, thanks very much.

I doubt that chipset is going to support multiple stations.

Use ath9k and you should have more success.

It definitely does not.

the reason of this unsupporting is chipset limitation, firmware limitation or linux driver limitation?
