We have moved all Comtrend 5374/5381u and Smart/RG SR505N/SR515ac modems into CC+.
It is now much easier to find the right modem and update WiFi passwords. Some troubleshooting features are also available for the modems.
The IP in NOMS should pull up the correct modem. If more than one result comes up open one starting at the top and go to Troubleshooting\WAN and select the PPP interface and confirm the username matches what is found in NOMS/MX480.
WiFi passwords can be set for customers the same way we do it for the Calix 854g/844e.
Let me know if you have any questions.
