Can not get the DNS address thru DHCP

[Looong]

Hi,

After I turn on Wi-Fi in android 2.2, it can connect to an AP thru DHCP,
but I found its DNS server address is not present, the phone's property:

[wlan.driver.status]: [ok]

[init.svc.wpa_supplicant]: [running]

[net.dnschange]: [2]

[init.svc.dhcpcd]: [running]

[dhcp.wlan0.result]: [ok]

[dhcp.wlan0.mask]: [255.255.255.0]

[dhcp.wlan0.leasetime]: [7200]

[dhcp.wlan0.server]: [192.168.1.1]

The kernel log:

Does anybody have a good idea to work out it?

Thanks in advance.

Hello,
It seems that DHCP server didn't give DNS information.

At first, do the same test with your laptop which has the WiFi
interface.
If the PC doesn't get DNS information, DHCP has a problem.
But if the PC does, please check the DHCP configuration in your
device.

Thank you,

Hi, Horace:

My laptop can get DNS ip address 192.168.6.1 thru WiFi, and other phone also can.

 

Could you tell me how to check the DHCP config in my device?

Modify some source code files or other any thing?

Waiting for your reply.

 

Thanks for your pointer,

Yulong Zhao

Hello Looong,
If your device runs on eng. mode, please check "/system/etc/dhcpcd/
dhcpcd.conf" like the below.

$ cat /system/etc/dhcpcd/dhcpcd.conf
..
option subnet_mask, routers, domain_name_servers
...

You can see "domain_name_servers".
If there is no, your dhcpcd might not take DNSs.

Although there is, if dhcpcd doesn't take DNSs, you'd better capture
packets and inspect the sources.

Thank you,

Hi, Horace:

Thanks for your kindly help.

Now it works.

Finally I found the wifi driver module I used was not present in /system/lib/modules, so I changed another one, then it works.

Thanks,

Yulong Zhao
