I am trying to run 802.11a and 802.11p WiFi on one laptop using shell scripts. I am getting all connections when I am doing "iwconfig" ( all connections means Wlan0 having 802.11p WiFi and Wlan3 having 802.11a WiFi).

I am using WiFi Dongle for 802.11a and using hardware with external antenna for 802.11p ( 802.11p works absolutely fine even 802.11a script is running)

I can ping devices which are in network of 802.11p but I can not ping devices which are in network of 802.11a.

I am running shell script on linux laptop to make it happen. I tried one scenario: I made 802.11a WiFi ON and kept pinging devices in network. all pings were going. and now I ran the 802.11p script, at this point, i got ping message "Destination host unreachable" on 802.11a devices.

is there any drivers issues on the laptop or any conflict which creating this problem. Please guide me in this matter.

  • This would require two separate 802.11 adapters. Do you have the required compatible adapters? – Ramhound Jul 15 '15 at 14:48
  • @Ramhound : if I am understanding correctly, yes I am using two different USB adapters for both WiFi. For 802.11a, I have a WiFi dongle connected to ubuntu laptop using USB port. For 802.11p, I have a hardware with antenna connected to ubuntu laptop using USB port. Now, I really don't know if you are really talking about these two adapters or two adapters in Ubuntu laptop. I have no idea if i need two 802.11 adapters in ubuntu laptop. Please correct me. – chetan Jul 16 '15 at 12:14
