I trying to connect to WiFi using on-board WiFi adapter of MangOH Yellow (v0.5.0) and it seems ok but no pings works: _root@swi-mdm9x28-wp:~# wifi client connect 0xa9f_ _Connecting…_ _CONNECTED: interface: wlan0, bssid: 78:24:af:97:ae:70_ _root@swi-mdm9x28-wp:~# ping 2001:4860:4860::8888_ _PING 2001:4860:4860::8888 (2001:4860:4860::8888): 56 data bytes_ _ping: sendto: Network is unreachable_ _root@swi-mdm9x28-wp:~#_ _wlan0 Link encap:Ethernet HWaddr 3C:E1:A1:E8:AA:4A_ - ``` inet6 addr: fe80::3ee1:a1ff:fee8:aa4a/64 Scope:Link* ``` - ``` UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1* ``` - ``` RX packets:20611 errors:0 dropped:9 overruns:0* ``` questions are: 1). it is seems that it is only IPv6 supported? 2). I tried to activate IPv6 on router (ASUS RT-N66U) but do not see MangOH board in list of connected deviced to WiFi. How to check WiFi connection status on board? ‘_wifi client status_’ would be usedful command 3) _How to get it working ?!_ in dmesg output all seems ok as well [84.436037] sdhci\_msm 7864900.sdhci: card claims to support voltages below defined range [84.451122] mmc0: queuing unknown CIS tuple 0x91 (3 bytes) [84.453030] mmc0: new high speed SDIO card at address 0001 [84.852677] wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11) [84.866763] wlcore: loaded [86.253204] wlcore: PHY firmware version: Rev 8.2.0.0.212 [86.304863] wlcore: firmware booted (Rev 8.9.0.0.17) [86.332112] IPv6: ADDRCONF(NETDEV\_UP): wlan0: link is not ready [121.441055] sierra\_startup\_monitor [155.327718] wlan0: authenticate with c8:e7:d8:9e:d1:b6 [155.344530] wlan0: send auth to c8:e7:d8:9e:d1:b6 (try 1/3) [155.361975] wlan0: authenticated [155.370417] wlan0: associate with c8:e7:d8:9e:d1:b6 (try 1/3) [155.375064] wlan0: RX AssocResp from c8:e7:d8:9e:d1:b6 (capab=0x411 status=0 aid=1) [155.384410] wlan0: associated [155.384458] IPv6: ADDRCONF(NETDEV\_CHANGE): wlan0: link becomes ready [155.616291] wlcore: Association completed. root@swi-mdm9x28-wp:~# ---

Btw, wlcore is the TI Wifi driver’s loadable core module. Do have the TI Wifi IoT card plugged in. Then you would get those messages. The TI is not the on-board wifi for yellow, the Cypress is, and you cannot run both them for 2 Wifi interfaces currently - Legato, does not support multiple Wifi interfaces also. The other possibility is that you have made changes to the root filesystem such that TI is the default interface in /etc/network/interfaces, i.e. /etc/init.d/tiwifi. Also, if the interfaces file has been nuked by default Legato will try starting the TI wlan. Let us know if either of these are issues. Zahid ---

I have fixed it by command: **/sbin/udhcpc -R -b -i wlan0**
