I get “cwmp.9005-Invalid parameter name” when I refresh some parameters from my CPE. I only have the problem with one model of ONT. How can I solve this? Thanks.

You need your vendor to fix this. The CPE is responding to a GPN with a set of parameter names, but when genie does a GPV on one of them the CPE is responding that the parameter doesn’t exist. The only way to fix this is figure out what the parameter name is and report it to the cpe vendor to resolve.
