Usb Wifi with android kk4.4.3 on IMX6Q-SABRESD

[ankurrahi1]

Hi all,

I am working with android KK 4.4.3 on IMX6Q-SABRESD board. I integrated Ralink usb wifi with it.

while Ping www.google.com , I am getting error: Unknown host www.google.com

but I am able to Ping google.com IP, local host IP and any other global IP.

I found, this error is because of DNS, but I am not able to fix it.

and I do connect WIFI from terminal (command line), How to bring it up on GUI ??

Any help would be appreciated.

Thanks in advance

Hi Jackie,

I fixed the above issue, try this out, this worked for me.

1. In $android/system/core/init/property-service.c, add below lines in function property_perms

          {"rw.", AID_SYSTEM, 0}

          {"net.", AID_DHCP, 0}

2. In $android/external/dhcpcd/dhcpcd-hook/20-dns.conf

    In function dnsaddr in, add below lines

         setprop dhcp.${interface}

          setprop net.dns${count} $ {dnsaddr}

          setprop net.${interface}.dns ${count}

3. run the commands after running dhcpcd (iface name)

    ndc resolver flushif <iface>

     ndc resolver flushdefaultif

     ndc resolver setifdns <iface> <domain> <dns1> <dns2>

     ndc resolver setdefaultif <iface>

Thanks

Hi Ankur,

Thanks for your help on fixing the dns issue. But I would like to know more whether you can bring wifi up on GUI. I have modified wifi.c but always gets wlan0: CTRL-EVENT-TERMINATING in logcat. However by commandline, wlan0: CTRL-EVENT-CONNECTED can be got, do you have any suggestions? Thanks.

Thanks Saurabh,

But this doesn't solve my problem, I have seen this before, driver integration and connection is working properly in my case.

I am facing problem in Pinging www.google.com, it showing me an error: unknown host google.com, whereas google IP ping is working.

I am also trying to bring it up on GUI, if you could help me.
