Hi Rudolf,Thanks for your response and comments.If you run ifconfig -a does your WiFi interface show up? If not there is an issue with the driver. Use dmesg and filter for the driver. Often a driver cannot load the firmware. What is your WiFi hardware?Not that bad, the WiFi interfaces was fine, but it could not get dhcp response and IP address so an automatic private IP address 169.254 was assigned mlan0 Link encap:Ethernet HWaddr D4:CA:6E:A4:E8:B4 inet addr:169.254.193.101 Bcast:169.254.255.255 Mask:255.255.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2 errors:0 dropped:0 overruns:0 frame:0 TX packets:56 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:330 (330.0 B) TX bytes:16392 (16.0 KiB)
This would typically mean that you are actually connected to a wifi network but the interface did not receive a DHCP lease for the IP address. the 169.254. is local IPv4 IP address which the interface would typically get if the DHCP client times out.
I could see WiFi information well, it is not a major problem, but the
subtle issues are connman and wpa_supplicant did not set up the WiFi
driver correctly.

I don't think that this is a wpa_supplicant issue. However, you can use connmanctl to manually connect to a wifi network:
$ connmanctl connmanctl> enable wifi connmanctl> scan wifi San completed for wifi connmanctl> services [service list follows] connmanctl> agent on Agent registered connmanctl> connect wifi_xxxxxx Agent RequestInput wifi_xxxxx Passphrase = [ Type=psk, Requirement=mandatory ] Passphrase? ******** Connected wifi_xxxxxx conmanctl> quit If that works the wifi authentication is OK.
Did you install the regulatory database?Did you mean to enable CONFIG_CFG80211_INTERNAL_REGDB? No, I did not install it in the Zeus version either so I don't see that could be an issue.
Only a wag on my side. Should be ok since the wifi driver is working.
What error messages are you seeing when attempting to connect to a WiFi network? Did you look at the connman logs?No error in connman, I don't think it is connman or wpa_supplicant issue, my suspicion is something missing in Honister built image to prevent connman and wpa_supplicant to set up the WiFi driver correctly. It is not the first time I have the WiFi setup trouble to get WiFi 169.254 address, when I upgraded from Thud to Zeus, I got the exactly the same problem that WiFi was assigned by a 169.254 address, no dhcp response, at time, I was totally convinced it was connman issue, I spend several months to debug connman and wpa_supplicant without any results, then after waiting several months to pull updated Zeus again, that problem was disappeared miraculous, that is why I suspect the same problem in oe-core and bitbake in Honister as well.
Well, ok then it looks like a dhcp issue. Did you attempt to set a static IP to test connectivity?
Eventually it could be a router issue. Maybe the router blocks unknown devices?
Honestly, I don't think the issue is related to connman or wpa_supplicant at all but on the dhcp level.Are there anyone in oe-core and bitbake tested connman, wpa_supplicant for the current Honister branch? I can help to test and to debug it if more advanced people in oe-core, bitbake, kernel, WiFi driver mwifiex can provide me more information.
Thank you. Kind regards, - jupiter
