Missing parameter in response

marcelolcosta · December 28, 2021, 9:25pm

Hi,
I am trying to read the Wifi information from a cable modem but it is giving the following error:
Missing parameter in response; parameter="Device.WiFi.SSID.1.SSID

Is there any test that I shoud do to troubleshoot this error?

Regards,
Marcelo Costa

Hi, from the debug log you pasted, you can see that you request the value of these parameters:

Device.DHCPv4.Client.1.IPAddress
Device.WiFi.AccessPoint.1.Security.KeyPassphrase
Device.WiFi.AccessPoint.9.Security.KeyPassphrase
Device.WiFi.SSID.1.SSID
Device.WiFi.SSID.9.SSID

And the device response contains:

Device.DHCPv4.Client.1.IPAddress : 100.64.20.146
Device.WiFi.AccessPoint.10001.Security.KeyPassphrase : 70858C6C
Device.WiFi.AccessPoint.10005.Security.KeyPassphrase :
Device.WiFi.SSID.10001.SSID : WIFI_2G858C6C
Device.WiFi.SSID.10005.SSID : WIFI_GUEST_0_4

this looks like a CPE firmware bug to me and my advice is to contact the manufacturer and provide this log.

Thank you Lavria!
I will check with the manufacturer or build an workaround (I believe it will be faster)

Cheers,
