Differences Between CcspWifiAgent and OneWiFi Applysettings:

CcspWifiAgent :

dmcli eRT setv Device.WiFi.Radio.2.X_CISCO_COM_ApplySetting bool true
dmcli eRT setv Device.WiFi.Radio.1.X_CISCO_COM_ApplySetting bool true 

OneWiFi:

#Any dmcli commands specific to SSID and AccessPoint execute the Below Access Point Related apply settings
dmcli eRT setv Device.WiFi.ApplyAccessPointSettings bool true

#Any dmcli executions specific to Radio level use the below Radio apply settings command
dmcli eRT setv Device.WiFi.ApplyRadioSettings bool true

Debugging Tips :

Below are the list of logs present in /rdklogs/logs for Debugging OneWiFi Issues.

For Additional in-depth Debugging one should enable below commands ,

• touch /nvram/wifiMgrDbg
• touch /nvram/wifiDbDbg
• touch /nvram/wifiWebConfigDbg
• touch /nvram/wifiHalDbg
• touch /nvram/wifiCtrlDbg
• touch /nvram/wifiMonDbg
• touch /nvram/wifiDMCLI
• touch /nvram/wifiLib
• touch /nvram/wifiLibhostapDbg

check for the respective logs in /tmp,

• tail -f wifiCtrl &
• tail -f wifiHal &
• tail -f wifiMgr &
• tail -f wifiDMCLI &

• tail -f wifiDb &

• tail -f wifiWebConfig &
