    can't connect to wifi

    brightcome

      I just received ultra96 V2 board.

      I try to start the board according to Ultra96-V2 Getting Started Guide- v1.1.

       

      The SD card is flashed with "ultra96v2_oob_2018_3_190917_8GB.img".

       

      The board can be boot up .

      The uart can be access and print info.

      The wifi can be found by my local PC.

      However, my local PC can't connected to the ultra96 wifi.

       

      I try to run the "./wifi.sh" in the uart . Info as follow

       

      root@ultra96v2-oob-2018-3:~# ./wifi.sh

      Successfully initialized wpa_supplicant

      ctrl_iface exists and seems to be in use - cannot override it

      Delete '/var/run/wpa_supplicant/wlan0' manually if it is not used anymore

      Failed to initialize control interface '/var/run/wpa_supplicant'.

      You may have another wpa_supplicant process already running or the file was

      left by an unclean termination of wpa_supplicant in which case you will need

      to manually remove this file before starting wpa_supplicant again.

       

       

      nl80211: deinit ifname=wlan0 disabled_11b_rates=0

      udhcpc (v1.24.1) started

      Sending discover...

      Sending select for 10.166.207.96...

      Lease of 10.166.207.96 obtained, lease time 43200

      /etc/udhcpc.d/50default: Adding DNS 10.130.158.67

      /etc/udhcpc.d/50default: Adding DNS 10.130.141.67

       

      I haven't installed mini-DP to dp cable, so I can't directly check the wifi status on ultra96 board.

      Can someone help on this issue?

      Thanks a lot !

          In your output from the wifi.sh script it looks like the board was assigned an IP address (Lease of 10.166.207.96 obtained) on your WLAN.  You can run 'ifconfig wlan0' to verify.  Is your PC on the same 10.166.207.xxx subnet?  If so you should be able to 'ping' the board from the host and the board should be able to likewise do the same and communicate on your WLAN and, if connected, reach the internet.
